Provided are a mattress structure and a production method of the same, relating to the technical field of inflatable beds. The mattress structure includes: a top layer, a sponge layer and a bottom layer that are connected successively, wherein a plurality of first grooves are provided in the sponge layer. In the mattress structure, a plurality of first grooves are provided in the sponge layer arranged between the top layer and the bottom layer, which can lighten the weight of the sponge layer and accordingly, the weight of the whole mattress structure; moreover, not only the weight can be lightened, but also the used amount of sponge can be saved, which means that it has the advantages of convenient use and energy saving etc.

A support cushion and a method of producing a support cushion are provided. The support cushion includes a base layer having a lower surface and an upper surface, and a plurality of surface coatings positioned atop the upper surface of the base layer, the plurality of surface coatings configured to allow an amount of air to flow through the base layer and the plurality of surface coatings, and the plurality of surface coatings further configured to provide a cooling effect. The method of producing a support cushion includes the steps of providing a base layer having a lower surface and an upper surface; applying a plurality of surface coatings to the upper surface of the base layer, the plurality of surface coatings configured to allow an amount of air to flow through the base layer and the plurality of surface coatings and further configured to provide a cooling effect.

A hospital bed may include a support structure, a controller, a pressure source coupled to the controller, and a hospital bed mattress carried by the support structure. The hospital bed mattress is carried by the support structure and has first and second ends, and first and second sides extending between the first and second ends. The hospital bed mattress may include a base foam layer, and transverse bladder pairs extending over the base foam layer and being coupled to the pressure source. The transverse bladder pairs may extend between the first and second sides and may be configured to provide longitudinal pressure differential and lateral pressure differential. The hospital bed mattress may have a multi-layer removable encasement surrounding the base foam layer and the transverse bladder pairs.

A mattress insert, able to be inserted into a traditional mattress, includes a plurality of compartments, each containing gel beads and water suitable for simulating the feeling, pressure relief, and temperature regulation of a waterbed. The mattress insert is placed into a foam structural material of the mattress, providing the mattress insert with support and preventing the spread of the gel beads within the insert. The foam core of the mattress may be either solid or rounded. This mattress technology and insert is useful for beds, including medical beds and dog beds, recliners, chairs, and sofas.

The present disclosure provides an inflatable bed, which relates to the technical field of inflatable beds. The inflatable bed includes an inflatable bed main body, wherein an air-filled chamber is arranged in the inflatable bed main body; a sponge layer is filled in the first air-filled chamber; a plurality of pulling ribs are arranged at intervals along the length direction of the inflatable bed main body in the second air-filled chamber. The air-filled chamber of the inflatable bed main body of the inflatable bed provided by the present disclosure is divided into a first air-filled chamber and a second air-filled chamber. The sponge layer is filled in the first air-filled chamber, and the pulling ribs are arranged in the second air-filled chamber.

An overlay mattress includes a foil mattress of plastic material in a surrounding envelope of textile material. The foil mattress has channels and a preferably self-closing valve for filling air into the channels that are also at least partly filled with fibers of so-called ball fiber and/or with foam plastics, at least in such an amount that the plastic material of the foil mattress is mutually separated. The channels extend transversely to the longitudinal direction of the mattress, and the channels are interconnected via air passages. Methods of manufacturing such an overlay mattress are also disclosed.

An inflatable air mattress device includes a cover internally defining a first and a second receiving zone for receiving a pump and an air mattress therein, respectively. The air mattress includes a plurality of parallelly arranged air cells, each of which internally includes a first air chamber located below a second air chamber and having an elastic member provided therein. The pump is held in the first receiving zone via a movement-limiting mechanism and is provided with an air input and an air release line for communicably connecting to each of the air cells. Since the air cells, the pump and the air input and release lines all are arranged inside the cover, the inflatable air mattress device has an esthetic appearance and occupies less space. The elastic members in the first air chambers prevent a user from contacting with a hard bed frame when the air cells are deflated.

A mattress and a bed. The mattress comprises: a support layer assembly (10), wherein the support layer assembly (10) is embedded with a pipe channel (11); an airbag assembly (20), wherein the airbag assembly (20) is located on the support layer assembly (10); and a pipe assembly (30), wherein the pipe assembly (30) is arranged at least partially passing through the pipe channel (11) and is in communication with the airbag assembly (20). The mattress and the bed effectively solve the problem of poor comfort of a mattress due to the fixation of an air pipe in the related art.

A static equilibrium adjusting system includes a bladder (10) and a regulation valve (20). An elastic restoration device (11) is arranged in the bladder (10) to support an external pressing force. The regulation valve (20) is in communication with the bladder (10) to provide an adjustable reverse-resisting force to resist an air pressure generated, in a direction toward the regulation valve (20), by the bladder (10). Through selection of a size of the interior space of the bladder (10) and a density and an elastic property of the elastic restoration device (11), a rebounding force is generated to cooperate with the reverse-resisting force generated by the regulation valve (20) to provide a supporting force to the bladder (10), so that an effect of static equilibrium is achieved among the external pressing force, the bladder (10), and the regulation valve (20).

What are described are shaped hot-cure flexible PU foam articles, preferably mattresses and/or cushions, wherein the hot-cure flexible polyurethane foam has been obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of at least one compound of formula (1a) and at least one compound of formula (1b) and at least one blowing agent and at least one catalyst.
