Sprung mattress with new design of adjustable cover, comprising chamber filled with granules in different density

摘要

The human body needs a different kind of support depending on the area to be supported and the position of the sleeping person. The new design of a sprung mattress has at least one layer (1) made of different types of springs (2), which can be differently tempered and/or accommodated within individual pockets. An additional layer (3) made of a case (4), filled with granules (5) moving freely inside their cover, is attached to the top and/or at the lower side (6) of the spring layer. The strength of the support offered by the flexible layer is determined by the amount and the size of the granules.
