The chair is comfy! I will give it that my only issue is it does t stay fully upright to the way I want it when I first got it after a couple days if I even lean back a little bit (even with it locked in place) it pushes back until it locks. I want to be able to apply ANY pressure and the backrest won’t lean.
This is a nice chair with a "cushy" seat. The instructions are a bit vague as there are only pictures no written instructions. I would give it 5 stars if the instructions were better.
I can sit in this chair for long periods of time without getting uncomfortable or having any muscle soreness. I'm an elderly person who sits a lot for my work.
