Very simple instructions and assembly although a few words to go along with pics would have been nice. YouTube always a great backup. Comfy chair and great sale price.
The first chair we brought home had a crack in the upper back support at the top of the chair. Once returned we got a replacement and the second chair has a broken air hydrolic that raises and lowers the chair. It does not work. After assembling two chairs we have chosen to keep this broken one. The thought of assembling another only to find something else wrong is not what we are interested in.
There a lot of adjustments that can be made on the chair to help make the chair comfortable. Too bad that the instructions for those adjustments are not clear. And some do not seem to work.
