The Salus Ambra mattress is a revolutionary new design that incorporates the company�s unique Aero-Cloud Diamond foam. The firm rating makes it ideal for front and back sleepers, delivering outstanding support and cushioning for a better night�s sleep. The complex design of the mattress makes this a premium option for those who like the feeling of foam but who also want a cooler, fresher sensation as an alternative to standard memory foam.The 26cm deep Salus Ambra mattress is a technologically advanced, single-sided mattress. It�s low maintenance, with no need to flip and turn, but it is advised that the mattress should be rotated from head to foot every few months to avoid dips or lumps from forming. The inclusion of a 3cm-deep core comfort foam layer adds to the supple yet supportive feel. The mattress comes with a removable cover that can be easily washed, keeping it fresher and more hygienic. A 5-year manufacturer�s guarantee provides total peace of mind.The unique Aero-Cloud Diamond foam layer not only responds to prevent pressure points from forming along the spine but also incorporates the company�s �Black Diamond� product which regulates temperature and moisture content. This not only gives you a cooler, fresher feel than standard memory foam, but is also more hygienic by preventing moisture build-up which can lead to mould growth.At the core of the mattress are 2000 individually pocketed flex springs that provide exceptional responsive support all night long. The adaptable support provides relief to joints and the lower back, giving a firmer feel but with no compromise on comfort.The 4cm deep base layer of Salus Support Foam creates a firm foundation that ensures a firmer feel. This makes the mattress ideal for back and front sleepers, giving an enhanced level of cushioned comfort for a more restful night�s sleep. Around the edges is a dense framework of foam that prevents that �side sag� feel, and provides a much larger sleeping platform with edge-to-edge support.
