A mattress topper for providing improved comfort to a sleeper comprises a pressure distribution layer defining an interior volume. The pressure distribution layer has substantially air-impermeable side walls and a substantially air-impermeable base, and a top surface having at least a region that is air permeable. Support material is contained within the interior volume. The mattress topper includes at least one electrically powered air circulation device for drawing air into the interior volume of the pressure distribution layer via at least one air inlet port. A lateral air-flow layer is disposed above the pressure distribution layer and is configured to provide substantially unimpeded air flow both upwardly and laterally.

A ventilated mattress includes a ventilation system with an air distribution layer and a gel cushioning layer over the air distribution layer. The air distribution layer may include channels in a surface thereof, while voids that extend through an entire thickness of the gel cushioning layer may include voids that communicate with the channels. As the ventilation system forces air into the air distribution layer, the air may flow through the channels, into and through the voids of the gel cushioning layer, and to a top of the ventilated mattress.

This invention includes a method to produce a customizable and user-configurable mattress foam core which comprises a plurality of transversely extended foam rods that were cut during the mattress production process. These transversely extended foam rods typically have a cross section of a convex shape, including triangles, squares, rectangles, circles, ovals and hexagons. These transversely extended foam rods can be replaced with foam rods of different firmness, creating more than 10 zones with varying firmness in each zone thus tailoring to the sleeper's needs, adjusting for their differences in height, weight, sleeping position, and comfort preference. Also, these zones together allow the user to configure the mattress for spinal alignment.

The transversely extended replacement foam rods typically have cross sections that are substantially the same shape as the pre-cut foam rods, but may also be of different shape. In one embodiment, the transversely extended replacement foam rods comprises foams of two or more different firmness in the transverse direction, thus allowing the mattress to be customized for multiple users with different sleeping needs.

A mattress having a first layer with a first layer top and bottom extending from a first edge to a second edge, a first side rail proximate the first edge, a second side rail proximate the second edge, additional layers positioned under the first layer bottom between the first side rail and the second side rail, and a first air module that creates airflow, positioned between the first side rail and at least one of the additional layers. The first air module can draw air from the first layer and direct exhaust air between the first side rail and the second layer. The mattress can define a first channel between the first side rail and the second layer that can permit flow of the exhaust air. The second layer can define a layer recessed portion at a side of the second layer that is adjacent to the first side rail.

Resilient cores preferably for inflatable bodies having resilient slabs that define a plurality of generally columnar holes or resilient arrays of generally columnar solids, methods for making such slabs and arrays, and articles incorporating the same wherein the cores further includes thermal transmission mitigation means for improving a core's resistance to heat transfer beyond the core's innate insulative properties. Non-exclusive and non-exhaustive examples of such thermal transmission mitigation means in slab core embodiments include consideration to hole or bore geometric cross section, frequency, pattern and orientation, the introduction of a thermal barrier at or within at least some holes or bores, and/or slab material selection/treatment. Non-exclusive and non-exhaustive examples of such thermal transmission mitigation means in array core embodiments include consideration to the geometric cross section, frequency (density), pattern and orientation of the solids, the introduction of thermal barriers within inter-solid spaces and/or solid material selection/treatment.

A mattress comprising a first layer comprising at least one channel extending laterally from a first side of the layer to an opposite side of the layer, and a plurality of foam spheres or hemispheres disposed in each channel. A mattress assembly comprising the mattress and a mattress foundation.

A body support structure comprising one or more gel layers, such as structures comprising a plurality of ridges and a plurality of valleys. Methods of forming the gel layers and body support structures comprising the gel layers. Systems for manufacturing body support structures comprising the gel layers.

This disclosure addresses mattresses. In particular, a mattress that includes a plurality of layers. A foam core of the mattress is constructed to have selected characteristics of support and cushioning, the characteristics varying from zone to zone of the mattress. The foam core includes at least three zones; a first zone corresponding generally to an area that supports the head of a user, a second zone corresponding generally to an area that supports the torso of the user, and a third zone corresponding generally to an area that supports the legs and feet of the user. A top surface of the foam core is formed with a plurality of parallel transverse peaks.

A mattress includes a first end and an opposite second end arranged in a direction of the mattress. The mattress is configured to have a first firmness pattern suitable for side sleepers when the first end is used as a head end and the second end is used as a foot end, and have a second firmness pattern suitable for back sleepers when the first end is used as a foot end and the second end is used as a head end. The mattress has a firmness distribution which is asymmetric about a middle line of the mattress which is perpendicular to the direction.

A therapeutic orthopedic mattress for pets includes a top cover, a first layer covered by the top cover, and a second layer underlying the first layer. The mattress also includes an antennae comprising an elongated wire having a first end positioned proximate a first end of the first layer and a second end longitudinally spaced apart from the first end proximate a second opposing end of the first layer. The antennae is spread out between the first layer and the top cover. In addition, the method includes a microprocessor coupled to the first end of the antennae and is configured to distribute a plurality of sequences of intermittent electrical signals along the antennae to the second end. The mattress also includes a plurality of magnetic discs and far infrared radiation discs dispersed over a top surface of the first layer.
