Heavenly Memory Slumberland. Slumberland are so confident that this mattress will take you to heaven with its comfort, that they’ve even put it in the name. It’s a bold claim, but one we can’t argue with as they back it up beautifully. The UK made mattress comes complete with 1100 luxurious body moulding pocket springs and edge to edge support, thanks to its foam encapsulation. The Heavenly Memory has an angelic, medium firm feel that is complimented with contoured airflow memory foam that allows the mattress to keep cool whilst dramatically reducing moisture build-up. Even though it’s recommended that you change mattresses every seven years, you won’t have to worry about the Heavenly Memory mattress ageing for a very long time as it comes with a massive 12 year warranty.
