Featuring 1000 individually pocketed springs, the Sleep Shaper Backcare Pocket 1000 is designed with your comfort in mind. To ensure support from edge to edge & a consistently comfortable sleeping surface, these pocket springs move independently from each other & are encased within a foam border. The Smartsilver cover, which is removable & machine washable, uses a silver yarn that is woven into the mattress cover in order to utilise silver’s natural antimicrobial properties to restrict bed bugs & dust mites, & to control the growth of bacteria, fungus, & mould. Such an innovative cover makes this mattress perfect if you suffer from allergies, & it means that you can wake up in the morning feeling fresh & well rested. Please note: Spring count refers to a 5ft Kingsize model.
