The massager and heat component quit working within the first 6 months of use.  After 3 months the padding flattened so much that it does not cushion the back bar of the chair which sticks out (I am 5'5, 140 lbs and use the chair approx 5 hours a night) I have to use pillows on it to sit otherwise its very uncomfortable.  The stool's bolts' holes were about an inch off from the correct spot to be drilled so I had to drill the holes myself.
