If you are looking for an adjustable lumbar support and adjustable arms to get under the desk then this chair is for you. Easy to assemble. Seat is mesh just like the back.
Would recommend. Have had it for a few weeks only but very supportive which was a main criteria for purchase. Wish there was a bit more padding on arms and at knee interface with seat. Overall very happy but you have to want support. Everyone may not enjoy how much this chair offers in that department.
Quite comfortable good adjustments rolls easily and silently good swivel firm thigh support … but no seat-tilt adjustment and a monster of a lumbar support that I don’t see how to remove and am not sure that would be a good idea requiring upright posture or to sit leaning back a cushion positioned above the lumbar thing. Recommend with those caveats.
