I have just tried a tempur mattress in Dreams and was offered a very good deal on the tempur 27 cloud deluxe in king size with 36months interest free option. How does your product compare to the tempur product as my wife and I both suffer from back problems which we think is down to our existing mattress. We have to look for a new mattress and i have been advised by some one who recently bought from you to look at your site and ask the question.We have had bad experiences in the past with memory foam and currently have a new goose down feather topper.What can you recommend?
