This mattress is the basic model of a medical mattress with high-quality pocket spring unit. It is a special spring unit, which consists of individually encased pocket coils in order to better accommodate the body by holding the vertebra in a proper position. The pocket spring unit allows individual adjustment of the body during the sleeping. With that, the mattress allows an adjustment based on the movement of the body and at the same time not allowing deformation of the vertebra. We should stress that the medical mattresses are used as a preventive against deformation and pain in the spine, which means that you should not think of getting one when the pain is already occurring. The medical mattress ‘NATURA GREEN PLUS’ offers you good price and quality and in its rank represents a great choice for every individual. The upper surface of this mattress has HR foam (high quality foam where its cells are open, air is squeezed in and out by body movement, much as you can squeeze water in and out of a sponge). The branded mattress ticking is made of 100% PES and is quilted with 200 gr. /m2 PES Wadding. Standard height of this mattress is 23 cm. Recommended for hotels.
