I purchased this 2 years ago for me and it's perfect and working. I bought another one and the lumbar support doesn't stay in place. I'd ask for a replacement but I don't want to spend the hour taking this one apart and putting another one together.
I bought this one to replace a gaming chair that my son was using and didn’t last very long I’ve noticed that he’s keeping a better posture on this one I also like the firmness but it’s new so I don’t know how long it will stay firm I like it so far
