Abstract: A mattress retainer for use with adjustable beds. The mattress retainer can be secured to an upper surface of a mattress support, between the mattress support and a mattress positioned thereon. In one embodiment, the mattress support is configured to engage a taped edge border of the mattress to thereby constrain movement of the mattress relative to the mattress support when the mattress support is articulated to raise and/or lower various portions of the mattress. The mattress retainer includes a channel formed on an outboard edge for receiving the taped edge border of the mattress. The taped edge border can be clamped within the channel to thereby fix the position of the mattress relative to the mattress support.

Abstract: A universal junction box for controlling the operations of an adjustable bed is disclosed. A microprocessor and control logic drive a plurality of motors based on received command signals to adjust the position of the adjustable bed. A universal power supply receives power from a source and converts the power to appropriate voltage levels to power the microprocessor and control logic and motors, wherein the universal power supply has automatic sensing for sensing the voltage of the source. A programmable RF receiver receives command signals from a remote control, wherein the RF receiver recognizes any remote operating in a predetermined frequency range.
