I felt like I was in the Princess and the Pea.
After months of sleeping on the floor, suddenly, I felt like I was sleeping very high up.
At some point I even felt like I was going to tip over and fall off the mattress, now raised a good eight inches off the ground.
The bottom of the bed doesn’t looked warped. The mattress feels firm and supported by the flat surface.
I’m still liking the bed very much.
