The Ortho collection has been specially designed for a firmer feel mattress without compromising on comfort. Made in Britain, this hand crafted mattress contains 1036 ReActive pocket springs, each working independently to provide total body support. It's upholstered with materials from sustainable sources, including Airstream, a breathable polyester. Silver micro particles are also contained within the fabric finish which ensures a clean and fresh anti-allergenic sleeping environment. This mattress is upholstered on both sides and should be turned with the seasons to ensure comfort and longevity. Match this mattress with a non sprung divan base or slatted bedstead to ensure extra firm support. This Ortho mattress is handmade by Hypnos Ltd, proud holder of a Royal Warrant from Her Majesty Queen Elizabeth II. With over 100 years of bed making experience, the brand prides itself on helping to deliver a deep, energising night’s sleep. Mattresses combine pressure relieving pocket springs and the finest natural materials to create a supportive and supremely comfortable sleeping experience.
