The color is more of a grayish forest green than actual grey which disappoints me.  I am just one body so the assembly took about three hours because I didn’t get one of the chair arms installed correctly.  All in all, I got it together and am writing this review from it.  The heat is really hot.  It takes a while, but it’s amazing.  The vibrations are also pretty good.  This chair is not oversized at all.  I’m 5’8” and my ankles hang off of the end.  I’m worried it will be too short for my Dad when he comes to stay with me after his hospitalization. The chair is very comfortable.  Love the USB feature. I will update in a month.
