The adapter for the heat/message feature didn't come with the parts for assembly, so it can't be used! The lift/lower time takes too long. The center of gravity is off, so the chair can tip over if you lean too much to one side! The padding on the arms is thin and you can feel the material that the arms is made of coming through! If I hadn't already thrown my other chair away, I would've returned this one, but I wouldn't have anywhere to sit. THE NEXT TIME I WILL BUY ONE FULLY ASSEMBLED, So I can test it out before I purchase it 🤬😤😡
