The seat cushion is soft but supportive, making it comfortable for long sitting sessions. It keeps its shape well and doesn’t feel flat over time.
The chair back provides great support and feels very comfortable against my back. The design helps me sit upright without feeling stiff, even after long hours.
Friends who visited tried sitting in it and were amazed at how comfortable it is. This chair definitely stands out from other generic office chairs I’ve tried.
What really impressed me about this chair is the armrests. They adjust smoothly and feel very solid, not loose at all. Whether I’m typing, using a mouse, or just leaning back to relax, my arms are always supported at a comfortable height.
I paired this chair with my gaming setup and it feels amazing. The adjustable lumbar support helps keep my back in a good position, even during long gaming sessions. Highly recommended!
The breathable mesh and the soft yet supportive cushion make such a difference. No matter how long I sit, I feel cool and comfortable. The chair looks great too next to my desk setup.
The folding feature is incredibly convenient. When I need to make space in my room, I just fold it away and it stays securely in place. Perfect for a small home office.
This S4 ergonomic chair has completely upgraded my workspace. The ability to adjust the height, tilt, and armrests makes it perfect for long work hours. I especially love how stable and supportive it feels — no more soreness after sitting for hours.
Aesthetic and great for the price
I've been looking for an affordable beige office chair with adjustable arm rests for awhile as many of the non-office or non-gamer chairs do not have adjustable arm rests and sit too low for my preference. I found this company randomly on google and purchased it immediately after seeing all the cute perks for less than $200. Here are my initial thoughts:
Pros:
-Custom arm rest: can go up/down, forward/backward, and even rotate
-Custom head rest height, custom lumbar back bar support (I'm not sure where to exactly put this yet)
-Retractable foot rest
-The chair can fold in half to slide under your desk if you need the space
-Bigger seat so you can sit cross legged
Cons:
-The legs/wheels were a bit difficult for me to put together. You need A LOT of pressure to snap them together. My fiancé had to help me because I was scared I was going to get my finger stuck --the rest was easy and quick to put together
-Chair is a big larger and might be too big for someone petite but I don't mind it
-Difficult to recline the chair - need a bit of pressure if you are going from the widest angle forward
-A little stiff overall like another use mentioned but not too bad. For me the seat is soft and pretty comfy. Some people may want more cushion though, but you can always get a seat pillow!
I can't comment on how ergonomic it is yet because I've only sat in it for a couple of hours but I enjoy it so far. I loved the color I got and don't regret it. The pink one looks super cute as well!
Very comfortable
Great budget friendly chair. Love the color and the fact that i can fold it for easy storage I see my desk! And it only took 30min to put together
I bought it as a present for my daughter and she loves it but I made a mistake and ordered it without paying attention to the colour. Too late now because I opened it.
She has to live with it. So, except the colour she loves it.
I really love the chair. A colleague at work recommended it and I bought it blindly without even trying it first. It is extremely comfortable and the leg rest feature makes it even better! The back support is perfect and I love that it can be folded to put it under the desk leaving more space around the office.
Really nice chair, highly recommended.
I love that the chair folds and can be stored under my desk when not in use. It's excellent for small spaces. I absolutely love the colour. The chair shipped much faster than expected. The assembly was very easy and the chair is very comfortable. I love the padded armrests, the foldable and extendable footrest and the customizable headrest. Virtually every feature of this chair can be completely customizable to my body and comfort. This is the best chair I've purchased in a long time and it's definitely a keeper!
Arrived quickly and was well packaged. It was quite easy to assemble and certainly feels very sturdy and comfortable. I think it is very well designed and everything fits together smoothly & securely it looks like great quality. Would buy again from this company.
I'm 5'1" and this chair is the perfect size for my small stature, but can be adjusted for someone taller (I'd say 5'6"). It's perfect for women. I love the foot rest position for crossing my legs slight lower than my hips. Assembled quickly and arrived very fast!
Love my Welax S4 chair - the foot rest has been a game changer and the ergonomic design makes my daytime desk job and evening/weekend work for my Master’s degree much easier on my back! I have scoliosis and proper support for my lumbar spine is a must - this chair provides ample support and the ability to recline and shift the weight off my tailbone is amazing. Highly recommend.
This chair has made my study sessions much more comfortable. The ability to tilt back and relax between tasks is a nice bonus. A great chair for students and professionals alike.
