## Description

Enjoy customized comfort and support with this ergonomic chair featuring 3D coordinated armrests, dual back design, and adaptive lumbar pillow for all-day productivity.

Review: Good for tall and heavy people - Im 1.83m and about 93kg and I fit perfectly in this chair. Plenty of space to sit, good inclining and being able to adjust the arm rests is actually good and an amazing feature. No weird squeaky sounds when inclined, back support is not adjustable but I didn’t find it awkward or annoying. The headrest takes a while to get used to and it might be a little bit too stiff for some people but I like it, it feels sturdy and it does feels nice napping in the chair. Overall Id say its worth it if you can find it on sale. Ive spent a month a half already sitting quite a king time on it and Im very very happy with this chair. It took me 20 mins to assemble, instructions were nice and clear.
Review: Good chair, happy with the purchase - Easy to build solo, pretty comfortable too. I bought it to replace a generic 'executive' chair which started creaking everywhere and peeling pleather. This is all mesh and it's a comfy mesh too. I always used to think the cushiony executive office chairs were the ones you'd go to for comfort, but this chair is way better and my back doesn't hurt after a day's work in it. It's whisper quiet, adjustable in the right places and doesn't feel like it's going to fall apart. That said, there is one plastic bolt cap on the right armrest that occasionally works it's way loose, but it pops right back in. The fixings that matter have not come loose and it remains as sturdy as the day I put it together. I've used it for a number of weeks/Months now, can't remember when I bought it. Very happy with it though. Recommended.
