Review on Himimi Kneeling Chair Ergonomic For Office, Height Adjustable Stool With Thick Foam Cushions For Home And Office - Improve Posture To Relieve Neck & Back Pain, New Upgraded Pneumatic Pump by Doug Ellingson

Got this as a secondary chair, which I rotate with my traditional desk chair for changes to posture, etc. Assembly was easy, and the chair is fairly comfortable; I do find my shins start to hurt after long sessions, but again, not bad for the price. My main gripe is that the casters tend to lock on their own, and the way the frame situates after adjusting for height, they don't swivel as they should all the time. As long as you're not sliding around in the course of your work, it's not really an issue though.Again, for the price, absolutely fantastic if your expectations are in check.
