It is designed for simplicity and provides features for good user comfort, reduction of shear forces and improvement of the microclimate.It has an automatic control unit with a user-friendly interface. The mattress system regulates independently and without manual adjustment the inner pressure of the mattress to different values based on the user’s weight and position.The control unit is equipped with the pulsating mode hence the pressure alternates and cells are emptied, but not completely. This gives a lower maximum pressure against the skin and slight movements in the mattress, which contributes to increased comfort and stability.All mattresses are supplied with a four way stretch hygienic cover which meets standards for hygiene, quality and safety. All covers are manufactured from modern, recyclable materials and are vapour permeable, which contributes to reduce the risk of skin maceration.
