The Maxim mattress has different layers of total anti-stress rest and has no pressure points, which will make your rest full and comfortable. The viscosoft material is a great conductor of electricity so it reduces the electrostatic charge of the body that is produced by accumulated friction, this helps to reach the REM phase of sleep by lengthening it and provides excellent rest. In addition, the stretch material used for its manufacture is hyperconductive, it is capable of eliminating large doses of thermal flow, achieving rest without temperature accumulation. It is also a great conductor of electricity so it reduces the electrostatic charge of the body produced by friction. H.R. core mattresses are an economical and more durable alternative to traditional mattresses. On the other hand, we achieve a complete and comforting rest thanks to the AirSense system that combines perfectly distributed layers of which this mattress is composed, thus guaranteeing optimal adaptability for any user.
