I purchased this chair for my wife and it was a hit. The lumbar support was the first thing I noticed about it after I sat in it. It took maybe 30 mins to assemble and it wasn’t difficult and I did take my time about it. The mesh seat and back is a plus also not only for the cushioning feel it has but also the coolness of it because air can pass through. There’s nothing we didn’t like about it. I would recommend this chair for people who sit long hours definitely.
Its been two months so I think I have a real feel of it now. Its definitely strange at first but eventually you get the right backrest position set. As the video reviews of it online say its the one for people who are above 5'9"~ vs the Hyken which is smaller. The chair forces you to sit deeper in the seat so the hammock material has enough to work with so if you want to sit on the edge of your seat that's a no the front is curved down and cheats the frame with a foam pad at that very point. If you like sitting on one leg again its a no because the plastic frame on the side edge will press against it. If you enforce good posture the chair is fine. The materials have held up quite well. The mesh is very strong but kind of grippy. When its cold you can put a towel on it to simulate fabric again. It does feel different from a fabric chair and you can't do things like lean over put a knee on it to help you reach something it sinks in too far to feel safe doing it. The mesh is a bit like a racket not a tennis racket but a badminton racket as they have thinner far more pliable strings but of course the chair is woven far more dense. The headrest is nice but mostly for looks I've never felt a need to stay leaned back that far. The only creaking I've had were from the casters which was strange but a drop of oil on the metal peg rims solved it One mod I did was to reverse the armrest pads so they don't jut out as forward to hit the desk. There are just two screws from the bottom and it can be flipped around. All in all its a good mesh chair for the money. Not susceptible to the fake leather peel and flake or the budget chair foam becoming flat over time.
