The 100% cotton, water-tight Respira sheet is more breathable than any other water-tight sheet on the market. The innovative Neotherm® membrane protects the mattress from liquids, enabling the optimal airflow at the same time. If you sweat during the night, liquid particles will evaporate more easily than from an ordinary sheet, enabling you to sleep more comfortable on Respira. This sheet is best paired with up to 30 cm thick and up to 200 cm long mattresses, but can also be used as a mattress protector.
