really comfy well supporting mattress, for a few years I've been suffering with hip and shoulder pain, sleeping on a branded mattress, but after a week, they are so much better, I now wake up pain free! like the zip off cover, meaning this can be cleaned. was a little unsure about the delivery method as it arrived rolled up, but it really doesn't seem to suffer from this. made it easy to get up the stairs. release3d it and after a couple of hours it had all filled out and was ready to sleep on. hard to find better at this price.
