I was not 100% of Mesh material however it’s surprising me so far. It’s comfortable and doesn’t loose it’s comfort for the several hours I use it for work each day. I would recommend. Try it out before buying to be sure it will work for you. Everyone is different.
The chair was easy to assemble with the instructions provided. I needed one extra tool a clamping pliers as the back tension knob was to hard to turn by hand. However the tension knob works fine. The chair is very comfortable. I hope the the chair material holds up under wear.
I love this chair! EXCEPT I have had 2 of them at work and the bar in the middle goes down to the floor and won't move back up! The chair seat is nice and roomy the mesh is comfy and I love the flexibility in the backrest. But once the middle bar hits the floor - you can't move it.
