Oh wow, absolutely the best mattress ever. I was unsure whether to go for this as it was really reasonably priced and I have paid a lot more for mattresses in the past, but I am so thrilled I took the chance. Since the very first night of sleeping on it I was pleased. However as the nights have gone on I am more and more impressed with it. It’s so firm but not solid. My husband is 7 stone heavier than me and there is no roll together. I’m now thinking of getting another one for the spare room :)
