Been shopping around for one of these for a while, the same product seems to be sold under a variety of "brand" names by as many different furniture outlets.  Found best deal on Wayfair so I finally bit the bullet.  Biggest surprise is that product came fully assembled so it took three of us to get the box upstairs but once we did setup was a breeze with two people.  Everything worked, build quality exceeded expectations for this price point.  Some reviews indicated motors breaking but barring any future experiences like this I'm a happy camper.  Works great with a king size Purple mattress although the massage feature is less than one might like.  I blame the nature of the mattress for absorbing a lot of the vibration from the massage units.
