It is a viscoelastic polyurethane foam shape memory at very high resilience. Its density can vary from 78-85 kg / m³ according to the manufacturing process.
It responds by taking the exact shape of your body and alleviates the pressure points, avoiding any friction that pushes us to return during our sleep. This is important, especially when we know that we turn around 40 times per night on a traditional mattress. Originally discovered by NASA, this technology is used by various brands.
Tempur
The Tempur mattresses are all made of a top layer of Tempur material thermal viscoelastic (memory foam) and laminated on a base of high quality polyurethane foam. Thickness of memory foam shapes vary between 7 and 9 cm.
Matelsom
Matelsom mattresses all use the technology of memory foam shape memory in packing with a thickness of 5cm. Matelsom combines this technology with all types of suspension: biconical springs, pocket springs, high density foam, or latex.
