This is my third 0 gravity chair. They benefit my physical aliments (back, hip, legs). I have one i have slept in for over a year. This chair did NOT work for me. Main issue is the chair didn't recline back enough to relieve pressure on my lower back.
Other negatives that may affect others. It is small. No one over over two hundred pounds is going to fit in this chair. Arm cushions are worthless.
Other than these factors, the chair is nice looking, quality built, love the tray, and the thin chair pad is also nice. It just doesn't work for what i need it for.
