Absolutely amazing mattress. Have had problems in the past with mattresses not wearing very well and not comfortable. I was a bit worried that it was being delivered shrink wrapped and rolled. When it came I thought there is no way that is going to spring out and expand to a ‘proper’ mattress.  How wrong was I Put it on the base and took the wrapping off as per instructions and wow, absolutely amazing.  Nice and thick, extremely comfortable.  Cannot praise this enough! We are awaiting stock for the double as we are going buy another one.  Brilliant
