Kneading massage chair that was not hard to put together, I did it myself.Chair is not over sized. It is perfect for myself 5'2" or for small spaces. It says heat although I cant say I can feel it. Therefore I only gave it 4 stars. Its not a vibrating massage. It is a kneading Shiatsu Massage. You can adjust the timer for massage duration, and adjust the chair manually into a recline position. Nice for the price.
