Nice office chair
Color: Beige
I recently purchased this chair for my home office setup. This chair is very comfortable and feels sturdy right out of the box. The seat cushion is thick and supportive, the back provides good support. I really like the flip-up armrests, which make it easy to slide the chair under my desk. Assembly was simple and didn't take long. Overall, it's a solid, well-built chair and a great value for the price.

Seat width short (Not tall people friendly) Very nice otherwise.
Color: Beige
I like the chair a lot. It’s very sleek and modern. One problem I have with it tho is the width of the seat. I am 5’9 and not necessarily a petite woman and when I do sit cross cross I seem to hang off the front. I do like that I can sit cross cross even with the sides of the chair up but the fact that I hang off the front is a bit annoying. There are plenty of other ways to sit on it tho and being able to maneuver it to where I can sit different ways is nice. I would say that this chair isn’t exactly tall people friendly. Also pay attention to the height and width of your desk because it isn’t exactly universal to fit under a normal desk. It is also super easy to put together and instructions are clear. Also as expected the back of the seat is a bit short and personally for me I like that a lot but word of caution for others that want the back of the chair to go up their entire back. I like it shorter because I’m able to sit sideways and have one side of the chair up and the other down and using the back rest as an arm rest. I did just buy it and am slightly concerned for it to not last purely because the manual said not to use it if it squeaked of creaked and it does both of those things. But I will still be using it until it breaks or it’s life span ends. It also seems very easy to clean the crevices are very short and you are able to wipe things out with ease.

Really comfortable upgrade from my old desk chair
Color: Beige
My old desk chair had been getting pretty uncomfortable, so I decided to replace it with this white one. After using it for a few days, I can definitely say it’s been a really nice upgrade for my workspace. My old chair was starting to feel stiff and uncomfortable after sitting for a while. This one is a lot wider and softer, which I really appreciate. Sometimes I sit cross-legged when I’m working on my laptop, and this chair actually has enough space to do that comfortably. The flip-up arms are also really practical. When I’m not using them, I just flip them up and push the chair under my desk. My workspace feels a lot less cramped now. The wheels roll smoothly and the height adjustment was easy to set up. I also didn’t expect to use the side pockets much, but I’ve been keeping a notebook and my tablet there, which is actually pretty convenient. I mainly bought the white color because I wanted something simple for my home office, and it looks really clean in the room. After switching from my old chair, working at my desk has been a lot more comfortable. It’s been great for longer work sessions, and overall I’m really happy I decided to get this one.
