Claims15
Mattress comprising an underlayer, an air chamber layer arranged above the underlayer, characterized by solid shaping material such as granular material incorporated in the air chamber layer, and adjusting means for adjusting the amount of air in the air chamber layer between a rest position, wherein the air chamber layer is substantially filled only with the solid shaping material, and an adjusting position wherein the air chamber layer is only partially filled with solid material and further with air under a pressure,
- wherein the adjusting means comprise air transport means for feeding and discharging air to and from the air chamber layer, movement detection means and control means for activating the air transport means in response to the movement detection means,
- wherein the control means are configured such that at the beginning of a movement on the mattress, detected by the movement detection means, the control means activates the air transport means for the purpose of feeding air to the air chamber layer in order to bring the air chamber layer into the adjusting position and, at the end of the movement on the mattress, the control means activates the air transport means for the purpose of discharging air from the air chamber layer in order to set the rest position.
