The Sealy Nostromo 1400 Pocket Latex mattress, also known as the Teramo 1400, uses Sealy\'s Posturepedic 1400 pocket spring system and innergetic latex to create an unparalleled sleeping experience. Providing you with all the support you need without being too firm, the Sealy Posturepedic Pocket 1400 Latex Mattress is designed to deliver outstanding comfort, whether you sleep on your back, your sides, or your front. The Posturepedic 1400 uses Innergetic Latex that immediately moulds to the contours of your body to support the spine. The use of Latex also stops mites and bed bugs, making it ideal for those who suffer from allergies.The firmness rating of 3 (Medium) means that this isn�t as hard as other orthopaedic mattresses, but the use of Latex makes it firm enough to provide the correct level of support all along the spine. The 1400 individual pocket springs flex and respond to the body�s pressure, allowing you to keep your spine in that all-important �neutral� position to avoid stress or pressure points. The design also ensures that there�s no roll-together, so everyone gets a great night�s sleep!The quilted Tencel cover is designed to keep your mattress at a cool and comfortable temperature, minimising moisture by creating a �micro-climate� in the bed. Added Purotex reduces the chances of mould growth, for a fresher, more hygienic sleeping environment.The Posturepedic Pocket 1400 is a no-turn mattress, meaning you don�t have to flip-and-turn on a regular basis. All you need to do is rotate it from top to bottom once a season. The construction of the mattress means that it always provides the correct level of support, regardless of the orientation.Which? is regarded as a benchmark for excellence, so if a product gets the coveted �Best Buy� award, you know it�s good!
