Only chose 1 star as I cannot go for zero!! We bought a Superking Hyde & Sleep Hybrid+ very firm mattress after using the Sleepmatch facility in Dreams and after only 7 months it is like sleeping in 2 troughs with a massive ridge down the middle, even after following the care instructions of turning the mattress [which handily has no handles!!] every so many weeks. As with others on here, a guy from Homeserve has been out and advises it is within tolerance 'quelle surprise' but if I want an independent survey which finds it is faulty, they will pay up to £60 and 'reconsider [not necessarily change] their decision' What a waste of time... I am looking into legal recourse, probably in vain, but it will make me feel better. Avoid Hyde & Sleep and avoid Dreams at all costs....you have been warned.
