SoniaI need a hard mattress for back injury. This one fits the bill beautifully! Very comfortable

MiriamEverything it says on the tin. It’s rock hard! We’ve had it now for about a month… Personally I love it. I suffered with sciatica and found this to help. My husband finds it a little bit too hard (like sleeping on a table!) so we will get a topper to make it a little more comfortable for him. No sagging- don’t know what people are talking about with that, it’s so exactly what I wanted.

AledBrilliant product. I have been sleeping on this mattress now for approximately 6 x weeks. I have subsequently noticed that my back does definitely feel better as compared to my previous old mattress. If you like a rock hard mattress, then this is the mattress for you.

DebaratiWe are used to firm mattresses, and although I have tried other firm mattresses, this is the only one that has worked great for me. Highly recommend for people who need an ortho support mattress. I also find the handle on the side of the mattress helpful in rotating and moving the mattress.
