The present invention is a mattress for infants which reduces positional plagiocephaly. In one embodiment, the mattress includes a first portion and second portion, where the second portion is inclined relative to the first portion. In another embodiment, the surface of the second portion of the mattress includes a pattern of raised areas and depressed areas to support the neck and head of an infant.

A mattress having a three-dimensional elastic structure of the present invention has a structure in which a main elastic body independently contracts and expands by multiple first to fourth auxiliary elastic slits which intersect with each other in left and right directions, front and rear directions, and up and down directions so as to form a three-dimensional air tunnel. Accordingly, when the first to fourth auxiliary elastic slits contract and expand, air is discharged in all directions of the main elastic body through the three-dimensional air tunnel so as to disperse the pressure by a human body, thereby inducing good blood circulation, and heat is released through the three-dimensional air tunnel so as to secure air permeability, thereby inducing maintenance of a proper sleep temperature so as to provide a more comfortable sleep environment.

In some embodiments, a support structures can be formed from a support structure matrix comprising a plurality of spring structures embedded within the support structure matrix. The plurality of spring structures can be formed from the same material or a different material, and can have the same or different durometers. The plurality of spring structures can be configured to deform and return to its original shape after deformation. The orientation and structure of the spring structures can vary depending on a desired durometer and/or function within the support structure.

The present invention relates to bedding product having heat-dissipation and support properties provided by structural protrusions on the surface of the bedding product. The bedding product may comprise a first layer of foam, that includes a base support having an upper surface and a lower surface and a plurality of open and closed protrusions located on the upper surface of the base support. Each open protrusion comprises a cavity formed therein, wherein the cavity has a depth of at least 0.5 inch

A support surface including a cutout on a bottom surface of the support surface. The cutout, which can include a plurality of cutouts, provides a controlled structural collapse of the support surface by varying a stiffness in a cross-section. That is, the area in which the cutouts are positioned collapses more easily than the surrounding area of the support structure, thus making the area with the cutouts perceived as being softer. The cutouts can reduce the peak pressures on the portion of the user's body (for example, the user's ischial tuberosities) that is positioned over the cutouts. The support surface can also include a low-friction interface extending across a top surface of the support surface.

An assembly for removing liquid from bedding, including a liquid impermeable layer portion, a padding portion disposed adjacent the liquid impermeable layer portion, and a suction conduit array portion operationally connected to the liquid impermeable pad portion and disposed between the liquid impermeable layer portion and the padding portion. A vacuum source is operationally connected to the suction conduit array portion. A liquid trap portion is operationally connected between suction conduit array portion and the vacuum source portion. A urine sensor and an electronic controller may be operationally connected between the suction conduit array and the vacuum source.

Mattress assemblies that provide user comfort and increased airflow generally include a viscoelastic thermally conductive infused polyurethane foam top layer; a composite comprising a bottom layer, a molded viscoelastic middle foam layer, and a perforated top viscoelastic foam layer, wherein the molded viscoelastic middle foam layer comprises a plurality of interconnected substantially parallelpipedal bodies, wherein each parallelpipedal body includes an opening extending from a bottom surface to a top surface and is separated from an adjacent parallelpipedal body by a V-shaped notch, and wherein the perforated top viscoelastic foam layer comprises a plurality of perforations extending from a bottom surface to a top surface thereof, wherein at least a portion of the perforations overlies the opening in the parallelpipedal bodies; and a base core layer, wherein the composite overlies the base core layer.

An assembly includes a mattress and an associated device, wherein the mattress has an open groove on a sleeping face, and the associated device is designed to at least partially block the groove when it is placed in the groove.

The present invention is directed to a mattress which is useful for people who have had gluteal surgery such as but not limited to gluteoplasty, commonly known as a Brazilian Butt Lift, Butt Implants, Fat Transfer, Fat Grafting, Liposuction, Pilonidal cystectomy, or other procedures affecting the lower rear area of a human trunk, which result in a person being uncomfortable when lying supine or sitting after the surgery or other procedure. The mattress in certain embodiments has an opening with at least one tube-shaped cushion which is adjustable for people with different body sizes and stages of recovery. The at least one tube-shaped cushion may be continuous, toroidal, round, square, rectangular, triangular, or any regular or irregular shape that would fit the buttocks. The at least one tube-shaped cushion may be inflatable, detachable, or permanently affixed in the opening. The mattress in certain embodiments may have the at least one tube-shaped cushion concentrically placed. The mattress in certain embodiments may have a raised back support for comfort along with a raised foot support to reduce the chance of blood clots. In other embodiments, the mattress can have an opening on a top or first side and a larger opening on a bottom or second side so that the mattress is reversible to accommodate different body sizes and stages of recovery. In other embodiments, the mattress may have at least one tube-shaped cushion in an opening on a top or first side and a larger opening on a bottom or second side to accommodate different body sizes and different stages of recovery. In other embodiments, the mattress may have a lumbar and thigh support which may be adjustable. The mattress and the tube-shaped cushion may be self-inflating in the case that they are inflatable.
