I like it! I fall asleep on my back but wake up on my side. My shoulder & hip do not hurt anymore when I wake up & don't wake me up because they hurt! My back feels less tight also. The mattress is short by about 1 1/2 or so, Hasn't grown in length. I haven't totally decided to keep it yet, it has been almost a month now. It does not sleep hot either. Easy to handle by one person, very minimal odor gone quickly.
After doing a bunch of online research and looking at all of ghostbed's competitors, I decided on the ghostbed; I could not have been more happy that I did. The first day my fiancé and I slept on it we both agreed it was a tad on the firm side. By the third night, either it had softened or had un-hardened (delivered in cold weather) but we both thought it was absolutely perfect. I cannot recommend it enough. Do some research and you'll probably go with it too.
My wife and I bought a queen size matress about 2 months ago. So far it has given both of us the best nights sleep ever. The matress is firm yet soft to where it conforms around you and supports you comfortably. Highly recommend it.
