The instructions are not at all clear, obviously written by someone who isn’t fluent in English…titled, In Structions. This chair is so flimsy and cheap, we decided to never hook up the heating or vibrating elements! It smelled of the pesticide foreign imports are often sprayed with! I had to run an air purifier for 2 days to get the smell out. We nearly tossed it to the curb before it was together! It’s not comfortable, perhaps for a small human it would be. In the end, I put a throw cover over this thing and it sits in a guest room. You have to assemble the outer edge of arm side for both arms, then disassemble the framed arm from seat of this chair. It doesn’t tell you that anywhere, but we figured it out by accident! It’s the only way to put the fabric skin over the arm/ side of the chair! Then the footrest fabric skin has to be stretched over and velcroed in place. The “In Structions” say to use the “magic sticker” to fixed seat cushion in place.
