Great price.  Does everything we need and more.  Took off one star because it lacks structure when you raise and lower the chair.  For instance, if you lean to one side and change chair position, it becomes crooked and I worried about stability.  If you sit straight to use the side buttons, you shouldn't have an issue.  Bought for a 6 ft tall man and chair depth is short.  Unsure about longevity in the short time we have had it.
