An air mattress comprises an internal structure for helping the air mattress maintain a desired geometric shape when inflated and for preventing shearing of the top and bottom surfaces of the mattress. The internal structure comprises a plurality of connection strips or a mesh web that are attached to a plurality of top surface connection points and bottom surface connection points.

A mattress with adjustable hardness comprises at least one resilience supplying module, at least one air bag module and a lining provided for the resilience supplying module and the air bag module to be placed therein. The lining is provided with a plurality of lattice-like units, each lattice-like unit defining a mounting space therein. The resilience supplying module is provided with a plurality of elastic bodies respectively provided in one of the mounting spaces. The air bag module is provided with a plurality of air bag units respectively provided in one of the mounting spaces. In this case, the air bag units may be inflated consistently, and the expanded volume of each of the air bag units after inflation may be limited to be uniform by the corresponding lattice-like unit. Thus, the problem of incapability of being kept evenness after inflation in the conventional practice is solved.

A filler formed to fit underneath a bed frame is provided. The filler includes a membrane. The membrane may include a top layer, bottom layer, and a sidewall connecting the top layer and the bottom layer together. An internal pocket is formed within the membrane. The internal pocket is capable of receiving and retaining a gas, thereby making the membrane an inflatable membrane. A valve is secured to the membrane and forms a fluid connection from the internal pocket to an outside, allowing users to inflate and deflate the membrane.

An inflatable mattress topper has a length and width substantially corresponding to the length and width of a mattress so that the inflatable mattress topper can overlie the upper surface of the mattress, substantially within the perimeter of the mattress. The topper has separate left and right inflatable chambers having common upper and lower walls, and each chamber having separate head, foot, left and right side walls. There are a plurality of generally elongate parallel beams between the upper walls and the lower walls of each chamber, each beam extending substantially the width of its respective chamber from a point adjacent the left side of the chamber to a point adjacent the right side of the chamber.

The inflatable pad includes an inflatable frame having a length and width that defines a pad area suitable for supporting a person lying thereon. A plurality of internal support members are configured to support the weight of a person lying thereon and elevate the person above the ground. The inflatable pad includes non-supporting regions that require less fill volume than regions that support primary support regions such as the hips and shoulder.

A multi-chamber inflatable mattress includes a main air chamber, upper and lower peripheral air chambers, and an upper air chamber. The main air chamber includes internal tensioning structures which cooperate with a bottom mattress panel and a lower intermediate panel to provide a generally box-shaped, mattress-sized inflatable structure upon pressurization. A second, upper intermediate panel cooperates with a top mattress panel to define an upper air chamber which defines the sleeping surface. The main air chamber receives pressurized fluid directly from a valve, while the lower and upper peripheral air chambers are in direct fluid communication with the main air chamber but not the valve. The upper air chamber is in direct fluid communication with the upper peripheral air chamber, but not the main chamber or valve.

A universal air handler unit includes a blower and evaporator juxtaposed one another within a compact, weather resistant cabinet adapted for outdoor installation. Ports for cool and return air ducts disposed on one side of the cabinet couple directly to the blower and evaporator respectively. Return air drawn by the blower into the cabinet passes across the evaporator core, then through the blower and back out through the adjacent cool air duct. Coolant lines couple to a stand-alone condenser/compressor unit. In a particular embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the overall footprint of the combination. In another embodiment, a manifold adapted to couple to the cool and return air ducts may be installed in various locations, the air handler unit slideably coupling to the manifold during installation, and easily decoupling and reecoupling for transportation and maintenance.

An air mattress includes a top sheet, a bottom sheet, an annular outer side wall, an annular inner side wall, a plurality of inner pull straps, and a plurality of outer pull straps. An upper edge and a lower edge of the annular outer side wall are connected to outer edges of the top sheet and the bottom sheet respectively to form an inflatable chamber of the air mattress, the annular inner side wall divides the inflatable chamber into an inner inflatable chamber and an outer inflatable chamber, and the inner inflatable chamber communicates with the outer inflatable chamber. The plurality of outer pull straps are spaced between the annular outer side wall and the annular inner side wall, and the plurality of inner pull straps are arranged between the top sheet and the bottom sheet.

A foamless, generally self-inflating sleeping pad comprises, in one embodiment, an inflatable sleeping pad frame to which is attached fabric top and bottom layers which are stretched into place when the frame is inflated. In a second embodiment, the frame and top and bottom layers of the sleeping pad are constructed of fabric however a central inflatable structure is provided, for example in the form of a Z shaped inflatable structure. In all cases, atmospheric air fills the interior volume of the sleeping pad and if required, a small volume of air may be added to the cavity by means of a two-way valve to increase the firmness of the sleeping pad.

The present disclosure provides an inflatable product comprising a wall enclosing an air chamber. A plurality of main tension members and branch tension members are disposed within the air chamber. The main tension members have an upper edge and a lower edge. The branch tension members each include a first connection region and a second connection region each connected to the wall of the air chamber. The branch tension members each include a third connection region located between the first and second connection regions and connected to the upper edge or the lower edge of the main tension member.
