Abstract: A bed is disclosed having an adjustable base support with an adjustable panel adapted for adjustment between raised and lowered positions, a mattress positioned on top of the adjustable based support, and a mattress retainer disposed under the mattress between the adjustable base support and the mattress. The mattress retainer holds the mattress in a constrained position in relationship to the adjustable base support as the adjustable base support panel is adjusted between raised and lowered positions.

Abstract: A mattress includes a liquid impermeable layer and at least one anti-microbial layer. A support core with expanded polystyrene beads is also disclosed.

Abstract: An air mattress includes a first inflatable compartment having a length and width, when inflated, sufficient to support a human body. The first compartment having a top, a bottom, and sides and is composed of at least two layers of vinyl, one layer of vinyl forming the top of the compartment and the second forming the bottom. A second inflatable compartment is disposed on the top of the first inflatable compartment and is secured to the first compartment along a portion of the first inflatable compartment. The second compartment extends generally the length and width of the top of the first compartment and is of a size, when inflated, sufficient to support a human body. The second compartment is composed of at least two layers of vinyl distinct from the two layers of vinyl forming the first compartment. The second compartment is inflatable to give the top of the air mattress a soft, pillow-like appearance and feel.

Abstract: The invention is drawn to an apparatus for supplying fluid, such as air, under pressure to a fluid accommodating means such as an air mattress and automatically adjusting the fluid pressure. The apparatus has a coupling device which attaches the apparatus to the air mattress. A housing encloses a motor, an impeller, a two-way valve and a solenoid. The solenoid opens the two-way valve to allow inflation or deflation of the air mattress. The motor is reversible and the impeller is used to force fluid into or out of the mattress. A controller is used to inflate and deflate the mattress. The controller can be attached to the apparatus or it can be a remote control.

Abstract: An airbed mattress includes a valve for controlling inflation of the mattress. The valve is normally biased to a closed position to prevent changes in the mattress' level of inflation. The valve may be opened by introduction of an air pump. The valve and air pump are designed to operate cooperatively by employment of an adaptor to facilitate the introduction of the air pump. The valve has an air passageway which contains an internal airflow control assembly. The control assembly operates to open the valve to passage of air upon introduction of the air pump and adaptor as well as effecting the closing of the valve when the air pump and adaptor are withdrawn. The valve also may have an extension adapted for a releasable connection with an air pump and adaptor for holding the valve open.

Abstract: A cover for a waterbed mattress includes a top layer suitably sized to cover the waterbed mattress and an inner backing layer of substantially the same overall outline as the top portion disposed so that the top layer lies over the backing layer. A bottom is spaced away from the top layer and the inner backing layer so as to provide a cavity for a water mattress, with the bottom disposed below the cavity and the inner backing layer being disposed above the cavity. The top layer is divided into at least three sections, each section extending substantially across the top layer. The first section is fixedly secured to the inner backing layer by stitches disposed in a first stitching pattern while the other two sections are fixedly secured to the inner backing layer by stitches disposed in a second stitching pattern. It is preferred that one of the stitching patterns be a continuous wave stitching pattern and that the other be a tack and jump stitching pattern.
