one of the things we all learn in adulthood is never to underestimate the power of a good night’s sleep – or, for that matter, the power of a bed that enables us to achieve that. While springs have long dominated the sleep industry, the last ten years or so have seen the growth of memory foam in the form of pillows, toppers and mattresses – and there’s good reason for its popularity surge. Originally created by NASA to improve the seat cushioning and crash protection of astronauts, it’s fair to say that memory foam (aka temper or viscoelastic foam) provides something close to ultimate comfort, with many likening it to sleeping on a cloud or floating. This mattress in this content is perfect for all types of sleepers, this is due to the HRX foam, which helps contour perfectly to your individual body shape for advanced sleep comfort. Plus Emma offers a 10-year guarantee and a 120-night trial where if you don’t like the Emma mattress you can return it for a full refund.
