The exclusive polyurethane " waterproof" cover protects the mattress from liquids and thus increases the life of the mattress. The additional breathable membrane allows the sleeper a restful sleep by reducing perspiration and heat accumulation. This membrane is also a barrier against mites and thus prevents house dust and mite allergies to the greatest possible extent. An additional finish with aloe vera brings beneficial properties to the skin and can have moisturizing and soothing effects. The mattress protector has 4 corner rubber tensioners, which prevent the mattress protector from slipping. The protector fits all mattresses up to 30 cm high and 200 cm long. The mattress protector is machine washable up to 95 degrees and tumbles dry (gentle drying).
