The chair is comfortable and easy to use. I like the locking system so I can select my perfect position depending on my mood.  I am glad I got the chair with the headrest it makes a big difference and is easily adjustable and removable.  I would have like the cushion to be more padded, I expected it to be thicker and have a more cushy feeling, which it was not.  Very glad I went with oversized chair.  Was just big enough to give some extra room but not big enough that you felt swalloed by the size of the chair.
