The siege lion needs a good ergonomic chair for sedentary back pain, and double 11 ergonomic chair unboxing experience

1. What is ergonomics?

1. Office sickness

Hello everyone, I am Nezha, a senior Java siege lion. My work has basically been modeled. Just one morning, staring at the screen, typing on the keyboard, sometimes because of too much concentration, I always feel back pain when I get up, and my neck is still a little stiff. Over time, it will deform the spine. This may be why everyone The office disease that is often said in the mouth.

Some time ago, I went for a physical examination. The doctor suggested that I change to an ergonomic chair. The first time I came into contact with ergonomics was during the 2021 Blog Star selection. The prizes for the fourth to tenth blog stars were Microsoft Ergonomic Keyboards. It feels mysterious.

2、Ergonomics

Ergonomics is a technology born after World War II. In addition to our common shape design, ergonomics actually includes various aspects such as the position arrangement of buttons and the design of explanatory text.
In a nutshell, in essence, the so-called ergonomics is essentially to make the use of tools fit the natural shape of the human body as much as possible, so that the person who uses the tool does not need any active adaptation in body and spirit when working, so as possible Reduce fatigue from using tools. The ergonomic design of the mouse is mainly the shape design of the mouse. To study this question, it is first necessary to study the natural structure of the human hand.

Ordinary computer chairs can only meet the functions of people sitting and turning. With the improvement of people's living standards, programmers' high-quality life concept, in order to keep up with the footsteps of fashion code farmers, designers pay more brains, and finally in ergonomics The direction is found on the keyboard, and the ergonomic chair can not only meet the needs of people to sit and turn, but also provide the comfort and health of sitting for a long time in the office.

3. Advantages of ergonomic chairs

(1) The back of the chair fits the curve of the lumbar spine, the headrest fits and supports the cervical spine, and maintains the natural S-shaped spine curve of the human body. The seat cushion disperses the pressure on the buttocks and thighs after sitting for a long time. This is the most important purpose of an ergonomic chair

(2) A better ergonomic chair also needs to meet the fit and support of the back, neck, buttocks and thighs in a dynamic sitting posture. After fine adjustment, no matter whether you are sitting upright, leaning forward, you don’t need to manually adjust the lumbar pillow frequently No matter you are sitting upright or leaning back, the lumbar pillow is close to supporting the waist, and it is truly realized: the feet are not tilted, the legs are not on the top, the support position of the lumbar pillow and the headrest remains unchanged, and it is smooth and linear. It's easy to get up. The assessment of this point is mainly the heart of the ergonomic chair—that is, the skill of the chassis. At present, the only thing that can really satisfy you is the chassis of glass fiber shrapnel. Baoyou's ergonomic chair and Herman Miller's ergonomic chair are both dominated by this material chassis.

Because the sitting posture of a person is different from the sleeping posture, it is impossible for a person to maintain a posture according to the needs of work when sitting, and any comfortable sitting posture will cause fatigue after a long time. Therefore, the best sitting posture is dynamic, and the only way to improve the health of the seat is to prolong the sitting time as much as possible while satisfying the dynamic sitting posture. And it can effectively guide the development of healthy sitting habits, which is the correct idea to design an ergonomic chair that truly meets the needs of health.

(3) Regarding the ergonomic chair, there is another function that is easily overlooked, which is the armrest. The main missions of the armrest are: to relieve the soreness of the shoulders, arms and wrists. For example: when you are close to the desk, adjust it to be parallel to the desktop, and then turn the armrest inward as much as possible to meet the direction of the forearm, so that you can firmly support your elbow when typing;

In order to avoid the phenomenon of wrist and arm hanging in the air when typing, the slightly tilted design of the front end of the armrest is also very worth choosing. Gently lift the front end of the armrest to support the wrist and forearm, let my body involuntarily lean on the back of the chair to avoid leaning forward. No soreness.

Here, I suggest that the bosses who read this article, for the benefit of the company, quickly replace the ergonomic chairs for the employees, so that I don’t have to pay for it out of my own pocket, haha.

2. How to choose an ergonomic chair?

The far water can't be connected to the near fire, so let's make one by ourselves.

Open the webpage, adhere to the consistent shopping habits of the straight man of steel, search for "ergonomic chair", the sales ranking, the top five can be considered~~

1. I think brand and sales are the cornerstones to avoid falling into the pit.

Looking at it at a glance, it is not surprising that the Baoyou brand ranks among the top five. Moreover, the Jinhao e 2nd generation is also the top seller of high-end ergonomic chairs.

Before this, the ergonomic chairs of Baoyou brand were well known in the Internet circles. Many code farmers in Goose Factory used Baoyou’s ergonomic chairs. As far as I know, they used the best-selling chairs. My friend Jin Haoe has to sigh with emotion that the quality of the chair is really an important backer for determining productivity.

2. Budget of course

Lock in the price range of 2500-3500, because I understand from the past upgrade experience of "squeezing toothpaste" that this kind of "saving" is actually a waste of money. Since I think this is a necessary purchase, the best choice is within the established budget In one step, three brands including Baoyou, Ergomax and Youpu have been targeted. After comparing the research and development strength, product reputation, quality, appearance, function, warranty and other factors, Baoyou was finally selected among the three brands.

3. Need to have forward tilt adjustment function

As a conscientious siege lion, when he is usually highly concentrated, his body actually leans forward unconsciously. So the forward lean function is very important to me. In addition to leaning forward, I prefer to sit upright when collecting materials and studying, and I like to sit slightly backward when resting. It would be even better if I can lie down directly when I am tired! In other words, the support of dynamic sitting posture is actually my core pursuit of ergonomic chairs. Otherwise, why should I change the chair? Of course, in the course of the homework preparation later, I got to know the importance of the support design of the back partition. So in the end, Baoyou 2022's latest upgraded version of the Jinhao E 2 generation was selected.

3. Zone 12 support

As the flagship product of Baoyou brand in 2022, Jinhao ew 2 generation mainly upgrades the material of the seat surface compared with the previous generation. Back-to-surface modular pressure zone design—that is, 12 horizontal zones with different tensions, makes the seat surface and back-to-surface better adapt to the physiological curve of the human body, accurately disperses the sedentary pressure, and supports different sitting postures. At the same time, the modular partition form can effectively correct and guide the sitting habits of the sitter through the force feedback to the human body, and more accurately and effectively disperse the pressure on our neck, back, waist, buttocks and legs when we sit for a long time, realizing Sedentary is not easy to fatigue.

4. About the upgrade of Matrex Quantum 4th generation technology mesh fabric

When Matrex tests the elasticity of nylon, it tests the same nylon. When it is extended to the same length, the tensile force that each needs to use. The greater the tensile force, the better its support, and the smaller the force required, it means elasticity. It is very large, and the possibility of deformation and aging will increase. As shown in the figure below, for example, in the test of the weight required for a 15% extension, the first generation of Jinhao requires a pulling force of 10.6 kg, and the second generation of Jinhao requires a pulling force of 15.2 kg, which shows that the life of the new generation of mesh will be greatly improved.

Under the premise of greater force and longer life, the sitting feeling is softer and more comfortable than that of Jinhao e 1 generation. The main reason is that the Jinhao e 2nd generation mesh adds elastic yarns, which makes the overall mesh softer and more comfortable to sit on.

5. Baoyou Jinhao ew 2 generation introduction

1. Bionic waist and back separation design

Baoyou's Jinhao ergonomic chair is currently the most well-designed ergonomic chair in China. This computer chair is innovatively designed with an independent elastic waist support structure, which can be adjusted according to the different weight and body shape of the sitter. This chair divides the back of the chair into two independent modular shapes, the upper and lower, and the two modules fix the direction according to the shape of the human body. Among them, the waist module has strong support for the spine, and the wide back module supports the shoulders of the sitter. It also has good protection. The excellent chair back split design of this chair protects the back and waist of the sitter better than a healthy double-back chair. (Source: "Industrial Design Issue 08, 2020: Exploration of Modular Design of Ergonomic Seats")

Lumbar and back separation engineering, 5 lumbar vertebrae are fully supported, the back is supported, the kidneys are not pressed, the shoulders are not pushed up, and the support of the headrest is indispensable.

At present, many ergonomic chairs on the market have made various attempts and partitions for the back of the chair, but as far as I know, the relevant ergonomic data report, in fact, the chair with the back partition is relatively more ergonomic. It is also one of the main basis for Baoyou to design the ergonomic chair with back partition, and it is recognized by consumers.

From the picture above, we can know that when we mark the lumbar spine and thoracic spine with dots, we can gather them into such a scatter diagram. The dispersion of the lumbar spine is not so large, but the dispersion of the thoracic spine will be larger, so the independent lumbar pillow is used to focus on supporting the waist. It is best to adjust the size of the elastic to concentrate on supporting the waist, while the back support should support The surface should be larger to support the more discrete thoracic vertebrae (that is, our back). On the other hand, the ergonomics of the low-back partition design chair of the Baoyou brand are higher. (Image source: Ergonomics in Europe and America, 18-65 years old, spine measurement data of more than 4,000 people)

Before I bought it, I was most worried about the problem of the air pump. Before, I always saw the problem of the air pump bombing the butt on the Internet. (Chairs at this price do not need to worry about these problems at all, because all products are certified by the international authority SGS.)

2. Overall structure

1. The aluminum alloy structure makes the chair stable and weighs stylishly;
2. Imported 4-level explosion-proof air pressure rod, 4 safety certifications, American TUV certification, 50,000 times of lifting and lowering pressure tests;
3. One-piece aluminum alloy chair legs;
4. Silent PU pulley, no damage to the floor, floor tiles, marble, smooth and free;

3. Product size information:

4, 6-dimensional dual-control automatic elastic waist pillow

There is another important improvement in Jinhao ew 2nd generation. You can decide on the support strength of the lumbar pillow. Usually the lumbar support of double-back chairs is adaptive, constant and immutable, only you can adapt to the chair. In addition to self-adaptation, Jinhao E2 also supports manual adjustment. The elasticity of the lumbar pillow can be adjusted through the knob at the rear, so that you can choose the most comfortable support strength according to different body types, avoiding the lumbar support of previous ergonomic chairs or Too hard, or insufficient support. The strength of the lumbar pillow is what you say, and the chair adapts to your needs. This is an essential change. The gene of Jinhao E2 waist protector and spine protector is stronger.

I usually sit and write code, and I prefer to adjust the support of the lumbar pillow a little stronger, so that the waist can be tightly supported, so that the entire spine is in a relatively straight posture, and the fatigue of sitting and standing for a long time is relieved; lying down When resting, the support force of the lumbar pillow does not need to be manually adjusted. The whole body is in a very stretched and relaxed posture. There is no obvious foreign body sensation in the waist, and the support force is just right. This should be adaptive lumbar pillow + manual fine-tuning of the waist brought about by support. In short, this lumbar support gives me the feeling that no matter what posture I am in, it can accurately support the waist.

5. Thinking and progress of Baoyou Jinhao e 2nd generation ergonomic seat on the modular design of dynamic sitting posture support

In the principle of ergonomic chair design, we first solve the problem of seat comfort. It is observed that people will subconsciously adjust their sitting posture every 8-10 minutes on the chair, so as to feel comfortable. From the point of view of medicine, it is also shown that the natural state of human spine is the most comfortable, and constantly changing sitting posture is very beneficial to the body, so no matter what sitting posture is, no matter how comfortable we feel, it is not the most ideal healthy sitting posture , the best sitting posture is one that is constantly changing. Nature and comfort exist in dynamics. Any static sitting posture maintained for a long time will damage the health of the spine and pelvis. In addition, we also need to complete some necessary actions on the chair during work, such as extracting data, answering the phone, picking up items from the ground, operating the keyboard and mouse, and talking to visitors, etc., all of which indicate that the chair must be able to meet the dynamic requirements. Based on this, Baoyou Jinhao ew 2nd generation has upgraded the modular design method to divide the chair surface into multiple modules, each module is relatively independent and keeps a distance. Gives clear force feedback. Compared with the traditional one-piece soft chair surface, it is easier for the user to adjust and change the sitting posture more psychologically, so as to meet the long-term healthy sitting needs. The chassis upgrade of Baoyou Jinhao ew 2nd generation ergonomic chair is based on the dynamic sitting posture support as the core upgrade - super forward and backward 5-speed linkage chassis, taking into account the forward leaning at the desk to focus on work, comfortable fit for sitting office, micro The state of reclining and relaxing pressure, as well as the super-large 138-degree reclined game and resting state.

In the dynamic support, the core component is the chassis of the ergonomic chair. Jinhao ew 2nd generation ergonomic chair's newly upgraded back tilt linkage drift unloading chassis adopts aerospace-grade shrapnel technology combined with four-link suspension support technology, so that the entire chassis not only takes into account the comfortable support and lightness characteristics, but also the performance of the actual experience It is also better than most engineering chair chassis.

There is also a layer of sound-absorbing cloth wrapped on the base, so that there is no abnormal sound when the chair is reclined. The polished metal is really beautiful, and the details are in place and simple.
The super chassis is equipped with 1-speed forward + 4-speed backward adjustment. During the whole process of leaning back, it provides weightless flexible support, so that the feet are not tilted, the legs are not pushed up, the waist support is always fit, and the neck is also supported, silky and smooth. The children in the family can lean back silkily, helping to get up without effort, and completely solve the pain point of light weight users who cannot easily lean back, and the problem of insufficient support for large men.

My favorite function is the forward tilt function of the cushion chair. It feels like a function tailored for programmers. The seat cushion and the back of the chair lean forward synchronously, which not only relieves the pressure on the abdomen and thighs, but also supports the waist. This is a qualitative upgrade and becomes very practical. I have only experienced this feature on Herman Miller before.

Have you ever found that when you are usually sitting, your back is suspended for a long time? One of the biggest reasons for this is that I didn’t pay attention to my sitting posture. The other is that most of my office style is leaning forward for a long time, facing the screen and keyboard, which naturally leads to the head leading the body to lean forward. The consequences of doing this for a long time are obviously not good. The entire back muscles are more prone to fatigue, and what is more serious is that it leads to excessive pressure on the lumbar spine (so in fact, pay attention to waist protection, sit in a correct posture, reduce pressure, and not rely on things).
This kind of (cushion + chair back) synchronous forward leaning design is aimed at giving you a support when your body is leaning forward, thereby reducing the pressure on the lumbar spine, especially when leaning forward to work at a desk (such as drawing, coding, etc.) , write code) let your waist have support, not too tired. Of course, it is best to maintain a standard posture at ordinary times.
It should also be mentioned that for the function of leaning forward, there are relatively more chairs leaning forward on the market at present, but the forward leaning of a single chair is actually unscientific, and the design of the forward leaning chair will make you hump every minute , referring to the two sitting postures on the second right, it can be concluded whether the function of the chair back leaning forward is necessary.

Therefore, the forward leaning of the chair is against humanity and the structure of the human body. Under the gorgeous packaging, it confuses the heart of use and overdraws your vitality. The last straw that presses down on the healthy waist is the forward leaning function of the backrest. Be sure to choose a seat cushion + chair back that can be tilted forward, especially if you usually do a lot of work at your desk, you should definitely choose the latter.

6. 6-dimensional suspension armrest

The armrest of Jinhao ew 2 is made of thicker and softer material, and the forearm of the armrest is widened to realize various adjustment functions such as height lifting, front and rear sliding, left and right sliding, angle rotation, front upturn and back tilt linkage. . In fact, I have always thought that armrests are the watershed between high and low ergonomic chairs, because when we sit on chairs, there are always different usage scenarios, such as coding, reading, playing with mobile phones, etc., and at this time the functionality of the armrests appears. Very important, good armrest design can make the whole arm easier.

Extremely rich use scenarios: Different from other ergonomic chairs, Baoyou Jinhao ew2 also adds an upturned function on the armrest. Whether you are operating a mobile phone to play games or code words, you can find the angle that suits you. All can have better support and relieve shoulder, arm and wrist pain.

If you are tired of writing code and want to play games, you can lift the front of the armrest and support your forearm as much as possible in a half-lying position. The soft and wide armrest is soft to the touch and will not oppress the inner muscles of the forearm. The heavy handheld doesn't make my arms tingle either.

7. Control experience part (single-lever control + electric control)

In addition to single-lever control and adjustment, Baoyou Jinhao ew 2 also designed a wireless touch function on the armrest. The two buttons on the front end of the left armrest correspond to the lifting of the seat surface and the tilting of the backrest. It is extremely convenient to operate, even if you are using it for the first time, you can quickly get started according to the signs.

The introduction of electronic control is a great improvement in the convenience of ergonomic chair industry, closely following the pace of modern smart homes. Lying on the chair, you can lean back with a light press and lock it easily in any recline position, making it very suitable for lazy people.

Careful friends, you may have seen that there are two buttons on the left armrest. One is to adjust the air pump to adjust up and down; the other supports front and rear adjustment. This is an electric ergonomic chair with a full sense of technology. The armrest also supports folding up, which is the best posture for lying down and talking about the glory of the king, which is really considerate.
Electric turn on the lying flat mode, let me change my body, the brightest boy in the office~~~

During the lunch break, I no longer have to lie down on the table, so handsome~~

After the actual experience, it feels super cool. It is a bit similar to the difference between an electric sofa and a manual. After using it, I don’t want to adjust it manually. It is very suitable for modern lazy people. You don’t even need to bend over to adjust it. You can just press it lightly The height and recline angle of the chair can be adjusted, which is a design that understands people's hearts. We can see Baoyou's dedication and sincerity in product development.

8. Foot support

The foot support is also a standard configuration of Baoyou Jinhao ew 2nd generation. It is relatively easy to open and unfold, and the space occupied when storing is optimized in place, basically without affecting the legs.

Ultra-comfortable, widened and thickened double-layer storage type recliner, better experience when lying flat with a large-angle chair back The support angle of the calf, the entire support surface is soft, large, long and comfortable. Once the calf is put down, it is quite comfortable to rest and relax. If you tilt the armrest to play two games, it is also very relaxed.

A tactile dot is designed on the elastic control of reclining, which is easy to identify the direction of elastic adjustment.

The reclining force can be adjusted through the gray rod on the base, which is also a very useful function. The grip is enlarged, so the grip is excellent. There are instructions for adjusting the direction of strength on it, and there are three raised dots. , From small to large, the elastic force is reduced when adjusted in the small direction, and the elastic force is increased when adjusted in the large direction. For example, if we go down like a trip, we can lean back by relying on gravity, which can reduce the elasticity appropriately. The position and height of the adjustment lever is just right, you can touch it with your hand, and it is easy to rotate it. You can get the right reclining force after a few turns, unlike some engineering chairs, which cannot be adjusted well after dozens of turns. In a relatively low position, you need to bend over and adjust before trying the elasticity, and then adjust.

9, chair back hanger

There is also a small detail above the back of the chair. Gently flipping the sides of the back of the chair will pop up the clothes hooks. The workers should like it. Hang coats, bags, etc., so that your desktop is no longer messy, and it is quite fragrant~

10. Overall structure

The back of the chair is made of aluminum alloy, and the lines of the aluminum alloy are beautiful and smooth, which makes the chair stable and weighs stylishly at the same time; Like Herman Miller Aeron; the armrest is very soft and thick, and the texture is very good; the brand LOGO on the back of the chair is very delicate, and the imported 4-level explosion-proof air pressure rod, 4 safety certifications, US TUV certification, 50,000 times Lifting pressure measurement; one-piece aluminum alloy chair legs; soft PU thickened pulleys, not hurting the floor, floor tiles, marble, smooth and free, etc., all details are very fine;

In fact, the problem I was still worried about before I bought it was the problem of the air pump. Before, I always saw the problem of the air pump bombing the butt on the Internet. However, Baoyou’s full line of ergonomic chairs use imported brands (chairs at this price do not need to worry about these problems at all, because all products are air pressure rods, and have been certified by international authorities SGS, TUV, etc., in terms of safety issues There is no need to worry about it at all.

11. Free installation

After the goods arrived, I found out that it is free of installation. This is amazing~~ (it saves a lot of trouble and does not need to call the master to install it at home, and enjoys the VIP only available at the 10,000-yuan Herman Miller treatment, highlighting the convenience of high-end chairs)

6. Summary

1. The brand-new chassis upgrade brings an excellent sitting experience, which satisfies the support of the waist, back, hip, thigh and neck in any different sitting postures. Super (forward leaning + backward leaning) 5-speed linkage chassis, taking into account the forward leaning at the desk to focus on work, the comfortable fit for sitting and office work, the state of slightly reclining to relieve pressure, and the super large 138-degree reclining game and resting state. It can be locked or not locked when leaning back. The locked position of the reclined position greatly reduces the pressure on the waist, because the back of the chair will not press you to bounce forward, and the feet do not need to be pushed hard. Of course, if you don’t like it Locked, I prefer to sit on a remote chair, and there is no problem if you don’t lock the recline gear. Compared with some engineering chairs on the market that can only be locked when reclined, or can only be unlocked, it is much better!

2. The function of folding the front end of the armrest can better take care of the coding pressure on the programmer's shoulder, forearm and wrist, and relieve wrist soreness.

3. The lumbar pillow is full of support, and the multi-level elastic adjustment function is also very practical in the actual use process, which greatly enriches the use scenarios and relieves my physical fatigue after working for a long time.

After experiencing it for nearly a month, I think Baoyou Jinhao ew 2nd generation ergonomic chair is the most worth buying. As an ergonomic chair with a price of less than 4,000 yuan, whether it is material or design, the price is increasing. The expensive international brands are on par, especially the addition of the wireless control adjustment function, which immediately widens the gap with other brands in terms of experience.
