An automatic deactivation mechanism is configured for an air bladder pump having a casing and a motor located therein to pump air into an air bladder from the atmosphere and through an air valve connected through the casing. The automatic deactivation mechanism includes a housing positioned within the casing and has defined therethrough a first aperture in fluid communication with the atmosphere through the casing and a second aperture in fluid communication with the air bladder through the casing. Included within the housing are at least two switches and a diaphragm positioned between the switches. The housing is sealed so that when a threshold pressure is reached therein, at least one switch is triggered by deflection of the diaphragm to automatically deactivate the pump by de-energizing the motor.

An inflatable mattress topper including an inflatable chamber which may be formed out of polyvinyl chloride with or without lamination or flocking. The inflatable chamber is designed to rest upon a support system, namely a bed without additional securing devices or may be integrated within a conventional mattress. The inflatable chamber being inflated by air to an adjustable level to provide the desired support for its user through plastic tubing connected between a pump and an air inlet sealed to the polyvinyl chloride chamber. The inflatable mattress topper is easily set-up for continual use or removed for occasional use.

A fabric sled for sliding upon snow has a composite contruction in which an interior cushioning assembly is enclosed within opposing top and bottom cover portions. The top cover portion is formed from a durable fabric material and the bottom cover portion is formed from a smooth, durable and waterproof material. The outer edges of the top and bottom cover portions enclosed by an outer edge and are stitched together around the perimeter of the sled along the outer edge to form an integral unit that contains the cushioning assembly.
