I am delighted with this mattress. It is firm. Can be rotated, flipped over, BOTH SIDES OF THE MATTRESS GOOD QUALITY this is a deal breaker!!!! my previous other branded mattress was a single sided mattress and it "dipped" which overtime got worse. its not too hard..im 16 stone, the mattress gives me support without being too hard. Iv had it for over a month and settled in with it. It also, for me has lots of support when sitting on the edge of the mattress...getting in and out no sagginess!!!! It was delivered within 10 days, carefully packaged. And the price!!! Super. Very impressed. Oh!! And the price?? SUPER!!

Perfect for adults and back issues- this is a great mattress. My partner and I are not small people and we’ve both had a good nights sleep on this, it’s in our spare room we had to downsize due to a new addition to our family.
