Ergonomic Mesh Office Chair, Adjustable Lumbar High Back Desk Chair 400lbs, 4D Flip-up Arms, 3-Level Tilt Backrest, 3D Headrest, PU Wheels, Swivel Rolling Computer Seating for Long Desk Work

Easy to assymble. Manufacturer provided good, clear instructions with the product. Now to the comfort factor. First off I've had back problems for years ever since I was on Instructor Duty at the EW school in Pensacola, Fl. In just the few days I've owned this chair my back has shown tremdous improvment. The lumbar support takes a little getting used to but once you have it adjusted correctly the chair is very comfortable. It actually forces you to sit with better posture. Would I buy it again? Definitely. Do I recommend it to others? Definitely. This is great chair and I feel lucky to have caught it on sale. Once again, highly recommended.

The assembly of this chair was very smooth. Lots of guides and detailed instructions. Everything clicked into place and made the assembly super fast. Took me only about 20 mins to assemble. Lots of extra parts, and everything felt intuitive. I can tell the designers put a lot of thought behind the assembly process. Overall, the chair is super comfortable, stable, and highly adjustable. Amazing product!

It was easy to assemble, and is a comfortable upgrade from my current chair. The headrest, back support and tilt are all great. I assembled the chair and relaxed in the chair and now I just want to buy a foot rest, and chill in the chair. The wheel base is strong enough that I am not worried at all about falling/flipping out if the chair if I give my full weight resting leaning back. No stability issues with the arms, head rest or back support. I agree with others that the seat is almost too small. I am a 5'11 250 with a 38" going 40" waist guy. If my hips were any wider, I do not think I would find the chair comfortable. The arm rests also only go so high, and I wish I could get them a bit higher. Taller folk beware. The mesh isn't too scratchy, which I've had problems with in the past. Pet owners beware, it catches the loose pet fur on your clothes, so in the future I may find that vexing. But for me, the chair does it's job, and I'm happy with the purchase.

Disclaimer - this is an initial review - only had this chair a few days Size: 6'4" ~280lbs The good: the materials and build quality overall is pretty good, not sure what more you could want for a <$500 chair. The only thing that worries me is how long the mesh will last. I'd be happy with 3 years to be honest for the price ($180 at time of purchase). The lumbar/cervical neck support is very good. This is pretty much why I bought it. It will help me force myself into a good posture since my neck is such a mess, both lumbar and cervical. The head rest is actually quite good. It could be slightly stiffer to stay in place maybe, but it's pretty nice. The smell - call me weird but the smell of new plastic in a room for a day or two is a pro not a con for me. It honestly looks pretty nice, not a huge plus for me but it does look sleek. The bad: The reviews saying the seat is uncomfortable are right....at least so far as it is a very narrow seat. If it was ~3-4 inches wider, it would be a 10/10 chair for me at least on initial use. The edges are a bit harsh on your hips if you are north of a 38" pants size. If you're sitting pretty straight, not really a problem. The mesh feels fine, it's not as good as a cushion but the tradeoff of breathability is worth it I would say. What I did right off the bat to help with comfort a bit was get some pipe insulation foam I had laying around in the garage, cut it in half, and lined the front half of the seat underneath with it. Just kinda stuffed it in there up against the edges as much as I could. Does it help? Actually....kinda, ya. I'd say it makes it a good 15-20% more comfortable at the edges. Picture attached (you can kinda see through and see what I did). Edit: I used the other half of the foam for the back half. So I completely lined the edge underneath with pipe insulation. It does actually help. I also figure this will keep the edges of the mesh from fatiguing as quick since it shouldn't pull down on it as harshly over time. The casters it comes with are pretty bad. If you buy a chair for <$500 though, you should be buying a ~$15-20 set of roller blade casters to swap in. I ran the stock casters for a day as the roller blade ones I got here on Amazon for $16 didn't come until the next day. The stock ones work, but they're quite slow. In my opinion, any reviews saying that the caster input area welds failing were partly due to the stock casters being slow in the first place. This makes you need to push more, and puts more pressure on these spots - making it more prone to failure. The welds to me don't look bad to be honest, and it doesn't worry me - if they failed I'd just reweld them myself. The arm rests are way too adjustable. They are honestly not bad, but they don't need any more adjustment than literally just going up and down. THIS WAS THE #1 REASON FOR NARROWING MY SEARCH DOWN TO THIS CHAIR - for playing guitar flip-up armrests are a must for me, which narrows down the search dramatically, as anyone reading this knows. But the arm rests aren't bad. Conclusion: As a big guy, this is a good chair that will help with posture. The seat is too narrow if you are size 38 or greater pants - it's undeniable. Hopefully the mesh holds up - if that is the case I'll be plenty happy for the price. If this chair gets a better version in the future with literally just a wider seat, I will absolutely buy it when this thing is worn out in (hopefully) like 3 years. NOTE: THE TOP LUMBAR SETTING ISN’T A SETTING IT IS THE RESET. So many people in reviews, including myself thought the lumbar didn’t stay set - it does, just the top most spot is NOT a setting it is meant to unlock it and reset to the bottom.

Sadly it doesn't match the marketing hype. It has a cheap, molded plastic feel and smell. Super uncomfortable for me due to a really poor lumbar support design. It's basicly a lump in the middle of the chair that you can slide up and down (but not remove) without any locking mechanism so it doesn't even stay in place. I gave it an extra star because I like the visual appeal.
