Only had it for a couple of weeks, but it's comfortable, just the right size (I'm 5'7") and the motor works fine.  It provides a fair bit of lumbar support, although it's easy to slide a small pillow into position if you want more.  Had a little delivery mixup (I bought on Cyber Monday, so lots going on), but Wayfair was great in following up and I was more than just satisfied as a result.
