Abstract: In a system for protecting a user from injury sustained during sleep, a sensing device is operated to automatically monitor orientation or posture of a user during sleep of the user. A signal is transmitted from the sensing device to a control unit, which is operated to activate an appliance so that the appliance generates an alert signal upon detection by the sensing device and control unit of an undesirable orientation or posture of the user.

Abstract: An adjustable contour mattress is provided with a multiplicity of zones each having a mattress height independently adjustable by a respective electro-mechanical actuator. The actuators are disposed within the mattress between a lower panel member and an upper mattress layer. A control unit is connected to the actuators for operating them to alternately raise and lower respective zones of the upper mattress layer. A remote control is operatively connected to the control unit and includes command input elements enabling an individual user to selectively operate the actuators independently of other ones of the actuators, whereby the user can adjust heights of the zones independently of one another.
