Very easy to install 2 people make it easy 1 person can be difficult. I am 275lb woman and I was a little weary buying this chair as a plus size person. I felt that this chair supports my weight very well and I feel very comfortable in it. The headrest is my favorite piece I get a lot of neck and back pain from my old chair. This new chair supports my neck and back and allows me to continue working while getting this support. I wasn't too thrilled on the price but it's better than paying $1200 for an HM chair!
THe chair is Ok. But if you are tall the head rest hits you in the top of your back. Very uncomfortable. Needed to remove it. Also the lumbar support seems not keep moving down so you have to continually adjust it.
