I have 2 degenerative spinal diseases. I was no longer able to sleep on a flat mattress of any kind as my hips tightened and sent pain down both legs. I started sleeping in my comfy recliner and had no pain, but after a few months that got old as it is narrow and you can not sleep on your side. I looked into a base that would lift the mattress at both ends so my bed would resemble my recliner. At a local furniture store I tried the EASE and loved it and bought one. Problem solved, I can now sleep in a bed again with no pain. I have been sleeping in it now for 3 weeks, still experimenting with the different positions the mattress can be put in. I only wish it had drop down rollers to move it.
