This is turning out to be the best bed! At first I just wanted one but then got to a point I needed one due to health issues. What a lifesaver! It came completely assembled except for the legs which were very easy to place and tighten. With help, bed was turned over and plugged in! Very quiet. Wonderful features on the remote (and the bed). I had a couple of concerns which I promptly addressed with Customer Service who were very gracious and quick to respond. I am using a 10" medium gel memory foam mattress by Beautyrest which fits perfectly and extremely comfortable. Very pleased with this purchase and Wayfair.
