This is my second GhostBed. My husband & I like the one we use at home so much that we decided to replace the Tempurpedic in our motor home with a GhostBed. My husband is a large man (6'4" - 320 lbs.) with severe back problems. It supports him well and he sleeps well on it. Be sure you get a mattress cover - one accident & you'll be thankful you did! One disappointment: I insisted we upgrade to a Luxe in hopes that it would sleep more coolly (I sometimes get hot). I can't tell a difference between the Luxe and the standard; however, the Luxe is about 2" thicker and does seem slightly more supportive.
The bed is overall great and the adjustable base is awesome. The only slight issue, which is to be expected is that with the mattress cover you don't get to take full advantage of the cooling features. Overall happy with the purchase.
I think I expected the bed to feel cooler than it does. I still have a hard time sleeping on my side at times, not everytime. But it has improved my back pain a bit and my husband's. I just wish it stayed really cool.
