Bought the orange firm mattress in November 2019 was quite comfortable for the first 2 months then we noticed a rigid down the middle and the dip either side which gradually got worse. Finally decided to go back to dreams and speak to them about it, they arranged for a mattress technician to and inspect it and because the dip either side was under the 3cm guidelines dreams refused to offer a replacement or refund. Awaiting delivery on a new mattress as we can no longer put up with pain and discomfort😡. Do not waste good money on purchasing the Hyde and Sleep mattress you may just as well throw it down the drain. Mrs J Webb Isle of Wight
