r/Ergonomics

A lot of chair setup advice comes down to the same things: elbows around 90°, feet flat on the floor, knees around 90°.

Those are useful starting points, but they don't always tell you whether the chair actually fits you.

A few checks I find more useful:

• Can you sit all the way back without the front edge of the seat pressing behind your knees?

• Does the lumbar support meet your lower back without pushing you forward?

• Can your forearms rest comfortably without your shoulders lifting?

• Can you recline a little and still keep your feet comfortably supported?

If one of those feels off, the chair can get uncomfortable pretty quickly even if your posture looks "correct."

What other fit checks would you add?

Hey guys,

I've read that being seated in a conventional seat for extended periods of time can lead to anterior pelvic tilt and consequentially, low back pain and compromised posture.

Somewhat recently starting a career in medical device sales, I've noticed a lot of surgeons and other health care professionals choose to sit in these types of saddle chairs.

I've tried finding some information online about the actual legitimate benefits of these chairs, but haven't come by much.

Does anyone here know of any actual peer reviewed studies that support the use of these chairs and confirms some of the claimed benefits? Or perhaps are there any highly regarded professionals that support the use of them?

Thanks!

A unidade da CPU pesa 4kg,ela é alimentada por um carregador gan.

Cada módulo tem um powerbank dentro, estou trabalhando para que ele vire um UPS "90%" real, ou seja, para que o powerbank assume em caso de queda de energia.

No futuro talvez troque por um powerbank da Xiaomi, aí talvez vire um ups 100%.

Hoje utilizo o powerbank de qualidade mais barato no Brasil, mas que não tem as mesmas caracteristicas do 212w da Xiaomi, com o que tenho não dá para alimentar e ser alimentado ao mesmo tempo sem esquentar, esse só como saída não esquenta em nada.

A unidade principal tem 4kg e cabe em uma mochila.

Usei uma CPU Dell Optiplex 3060 mff que tinha,hoje tem cpus muito mais leves, mas o custo é proibitivo no Brasil.

Laptops não são ergonômicos, e Cyberdecks são menos ergonômicos ainda, o meu é um portable desktop.

Ainda preciso comprar uns adaptadores para esconder um pouco os conectores.

Hi everyone, hope you’re having a great day!

I’m an industrial design student working on my thesis about laptop ergonomics

I’ve put together a short survey and would really appreciate it if you could take a few minutes to fill it out, and share it with anyone you think might be interested. I don’t have a huge network myself, so getting this in front of the right community means a lot — hoping to reach enough people for solid, meaningful data.

Thanks so much for your time!

This was my solution. You can sit on any part of the table and you will not hit your knees!

For some context, I’m a software engineer who works from home and uses the desk for gaming as well. I am 162 cm (5'4") tall and weigh around 62 kg (137 lbs.), so finding an ergonomic chair that properly accommodates my height and build can sometimes be challenging since I have a small build. After previously sharing my own personal review of the LiberNovo Omni, I was contacted by ProtoArc, who offered me the opportunity to try their EC200 ergonomic chair. Based on my height and build, the EC200 was the model they felt would be the best fit for me. Before getting into the review, I want to make a couple of things clear. I am not a professional chair reviewer, and this review is simply based on my personal experience using the EC200. I’ll be approaching it in the same way I approached my LiberNovo Omni review: from the perspective of a regular user, focusing on what I liked, what I didn’t like, and how the chair actually feels to use. The chair was provided to me free of charge by ProtoArc for the purpose of trying it out and sharing my thoughts. This does not change or influence the opinions expressed in this review. Everything below reflects my genuine experience with the chair.

My experience with chairs is also fairly limited. Before the EC200, the two chairs I had meaningful experience with were a Trust GXT gaming chair (around 250eur) and, more recently, the LiberNovo Omni (around 1000 euro). Both sit at different price points from the EC200, so I’ll keep that in mind throughout this review rather than expecting a roughly €190 chair to compete directly with more expensive alternatives.

Keeping in mind that the EC200 is a chair that goes around €190, I was genuinely impressed by the packaging. Everything was well organized and securely packed, and the overall presentation had a surprisingly premium feel for a chair in this price range. Assembly was also a breeze. You don’t need any of your own tools apart from your hands, as everything required for the assembly is provided in the box. The different parts and hardware are clearly labelled, and the included step-by-step instructions are straightforward and easy to follow.

Considering the price point, I think the overall build quality of the EC200 is very good. The chair is definitely heavy on plastic. However, where it matters to me, everything feels solid and well put together. More importantly, during normal use I've experienced no squeaking, creaking or other unwanted noises from the chair. Whether I'm sitting upright, moving around or reclining, everything has remained quiet and feels sturdy. At this price point, I think ProtoArc has done a very good job with the overall build quality.

One of the first things I noticed when I started using the EC200, and something that quickly became one of my favorite features of the chair, is the headrest. The headrest immediately stood out to me compared with what I was expecting from a chair at this price point. As a short person, headrests are often a bit hit or miss for me. I usually find myself having to stretch or adjust my sitting position just to properly reach them, which somewhat defeats their purpose. The range of adjustability is really good, and I was able to position the headrest exactly where I wanted it. In fact, for my height, I actually prefer the EC200's headrest to the one on my LiberNovo Omni.

The EC200 is also the first chair I've owned with a mesh backrest. One of the first differences I noticed was just how much cooler my back stays compared to both the Trust GXT and the LiberNovo Omni.
Living in Malta, where the climate can get very hot, particularly during the summer, this is something I appreciate more than I expected. Obviously, this is partly a benefit of mesh chairs in general rather than something unique to the EC200, but since this is my first experience with one, its breathability is one of the things I really enjoy about using the chair.

The lumbar support is good and does what I would expect it to do. It can be adjusted up and down, which makes it easier to position it correctly against your lower back, and you can also fine-tune how aggressive the support feels. I am able to adjust the intensity, as you can make the lumbar support more pronounced if you prefer stronger pressure or dial it back for a more subtle level of support. Overall, I don't have any major complaints about the lumbar support. It is still better than the Trust GXT (which is a more expensive chair) but not as good as the LiberNovo.

The armrests are where the first signs of the EC200 being a budget-oriented chair start to show, and I would consider them the weakest part of the chair. They only move up and down. There is no forward/backward adjustment or other positioning that would allow me to fine-tune where my arms sit relative to my desk. This creates a practical problem for me. If I raise the armrests so that they align comfortably with the height of my desk, their position prevents me from getting as close to the desk as I would like. As a result, I end up sitting slightly too far away and have to lean forward a little to comfortably reach my keyboard and mouse. Here the other two chairs have a better option.

The seat itself can be adjusted forward and backward, giving you some control over the seat depth. Since I'm short, I keep it pushed all the way back, but I can definitely see the additional depth being useful for taller people. This is one area where the EC200 actually offers more adjustment than my LiberNovo Omni, as the Omni has a fixed seat depth. Where the seat falls a little short for me, however, is the firmness of the cushion. I generally prefer a softer, more plush seat. This becomes particularly noticeable during longer gaming sessions. I am not a couch gamer but a desktop gamer so I recline in the chair and put my feet up on the desk, and after sitting like this for an extended period, I can start to feel some numbness and discomfort around my backside. I would personally have preferred a little more cushioning or softness here. That being said, the seat is still considerably more comfortable than the one on my Trust GXT, which I found much harder and less forgiving.

The recline mechanism is a tilt-lock system. Personally, this is fine because when I'm gaming and want to recline, I tend to go all the way back anyway. The bigger issue for me is what happens to the rest of the chair when I recline. The armrests, headrest and lumbar support don't really stay in sync with my body as I move from an upright position into a reclined one. At full recline, I can barely reach the armrests, the headrest ends up much closer to the top of my head rather than supporting my neck, and the lumbar support moves too high relative to my lower back. This means that if I want everything positioned correctly while reclined, I have to readjust them. For someone like me who switches between working upright and reclining while gaming, this can become a little inconvenient. It's not something I would necessarily hold heavily against the EC200 given its price though.

TL;DR

It is not a premium chair BUT it is a very competitive and capable budget ergonomic chair with moderate adjustments considering the price point. Best part is the headrest and the weakest part is the armrests.

Positives :

• Very good build quality for roughly €190; sturdy, quiet, and free from squeaking or creaking.
• Well-organized packaging and an easy assembly process with all required tools included.
• Excellent, highly adjustable headrest, particularly for shorter users.
• Breathable mesh backrest keeps you noticeably cooler during warm weather.
• Adjustable lumbar support with both height and intensity control.
• Adjustable seat depth accommodates different heights and is especially useful for taller users.
• Overall comfort is considerably better than the Trust GXT which is more expensive.

What could be improved :

• Armrests only adjust vertically and can prevent you from sitting close enough to the desk.
• Seat cushion is quite firm and may cause discomfort or numbness during longer gaming sessions.
• Armrests, headrest, and lumbar support do not remain properly aligned with your body while reclining.
• Switching regularly between upright working and reclined gaming may require readjusting the chair.
• It is quite plastic made but it is to be expected at this price point.

My workspace is squeezed right next to my bed so I don't really have room for one of those massive office chairs. Meanwhile, I'm also an illustrator, which means one of my hand is constantly drawing and the other is reaching for keyboard shortcuts. My old chair never supported both positions properly turns out I usually end the day with a sore neck and back. I recently switched to a more adjustable chair, and being able to position each armrest separately has been especially helpful since my drawing arm and keyboard arm need different kinds of support.

Curious.. What features do you guys actually look for in an ergonomic chair?

Best sit/stand chair on the market! I have been using this chair for few years now and it has helped my back issues tremendously. it is worth its weight in gold and definitely worth investing in. numerous drs, injections and therapy did not touch my back pain, this chair enabled me to continue my desk job for many more years to come. I can’t be more grateful!!

Everyone in our office has a normal desk with a space for their keyboard. I’m stuck with this corner style right now. I have to rest my arms and elbows on each side in order to type. I’m all scrunched up and I am concerned about long term affects.
We are planning to remodel so I’m thinking about asking to have a new desk put in that has the regular keyboard cutout.
Looking for opinions from everyone.
Am I looking at future issues if I continue to rest my elbow and arms?
Am I wrong for wanting this fixed?
