The innovative viscoelastic foam of the Original MED pillow (A: height 70 mm) offers optimal pressure relief and is breathable. It is also characterised by its reduced temperature sensitivity; it does not become "hard" even in the cold (>10°C). Ideally suited for sensitive and pressure-sensitive persons who are looking for gentle and soothing pressure relief. The two lower inserts (B: 27 mm thickness and C: 18 mm thickness) are made of PuraCell Hydro Soft foam. This special material has a higher restoring force than the viscoelastic foam of the pillow. This optimises the height stability of the pillow and ensures efficient moisture regulation for a healthy sleeping climate. The material is more durable than the viscoelastic foam. This simplifies changing the sheets and taking off and putting on the cover.
