The Hybrid Inter Rolled Mattress from Simba has been designed by sleep experts and specialist engineers to create an enhanced sleep experience thanks to 4 layers of their signature technology.The unique Hybrid mattress is designed to feel comfortable to everyone, no matter their shape, size or sleeping style. It offers improved pressure relief and full body alignment; Simba’s patented, signature tech is designed to create a ‘hugged’, cradled feeling in the upper layers and more support in the base layers, with adjustment for hips and shoulders.A medium firm feel perfectly complements the specially engineered Aerocoil micro springs within this mattress that help to align your entire body. You won’t be able to feel them, but they’re designed to do what Simba is known for: offer full body alignment and support pressure relief.The famous Simbatex foam within this mattress has a special open structure that makes it cooler than regular memory foam. It also has greater elasticity, helping it bounce back to shape once pressure is removed, so you enjoy a unique, personalised level of comfort every night, without worrying about compression. Infused with graphite, this material actively draws heat away from your body for a fresher experience free of humidity and excess warmth.With the help of the ingenious zoned CentiPur base, your heaviest pressure points are optimally supported, encouraging a healthier sleeping position. In fact, with seven key support zones, this base ensures your body receives expert pressure relief exactly where it needs it.
