Our memory silver plus mattress combines the natural benefits of silver, the world's oldest natural antibiotic, with pressure relieving materials. The luxury cover is enriched with Silver fibres, which have natural anti-bacterial and anti-odour properties that help eliminate unpleasant odours caused by moisture absorption in the mattress. It also has the benefit of an anti-static shield to protect the mattress from dust particles that can cause allergies. Once removed from its packaging, the mattress should be left uncovered in a wellventilated room so it can air thoroughly. At Argos Home we want you to get the best night's sleep possible, so we offer a 100 night comfort promise on our mattresses. Try your new mattress for up to 100 nights and if you aren't sleeping soundly, we'll offer you an exchange for one that suits you better. Part of the Dormeo collection. Medium feel.
