An internal support system for a cushion, mattress or the like, for supporting the body of a user, the internal support system including: a main portion having a body facing side that substantially opposes a base side; and a support portion located at least partly within the main portion, the support portion including a core portion and at least one peripheral portion which extends laterally from the core portion, wherein the height of the core portion is greater than the height of the at least one peripheral portion, the height being that as determined in the direction from the base side to the body facing side of the main portion, wherein the support portion is more resistant to deformation than the main portion.

A method for customizing a mattress includes acquiring a three dimensional image of a body of a user and preparing, by a processor, a three dimensional model of the body of the user using the three-dimensional image. The method also includes dividing, by the processor, the three dimensional model into a plurality of sections arranged parallel to each other and arrayed along a height of the three dimensional model, and determining a downward pressure to be exerted by each of the plurality of sections on the mattress. The method further includes determining, by the processor, one or more parameters associated with at least one portion of the mattress adapted to be arranged underneath an associated section when person lies on the mattress based on the determined downward pressure or topography.

A mattress configured for placement on a foundation that has forced air ventilation with a plurality of air vents on the upwardly facing side of the foundation. The foundation providing a first flow of air having a first temperature and a second flow of air having a second temperature, the mattress defining a first plurality of air flow paths configured to direct the first flow of air toward a first occupant of the mattress and a second plurality of air flow paths configured to direct the second flow of air toward a second occupant of the mattress. The mattress being configured so that air from the air vents is permitted to pass through the mattress.

A foam core for a mattress including a supporting layer for supporting the vertebral column, the supporting layer including an upper part and a lower part. Different body support regions are provided in the upper part along the longitudinal direction of the foam core, a plurality of the body support regions having at least one recess in the material of the foam core. At least one reserve region is provided in the lower part and has at least one recess in the material of the foam core. The foam core is formed such that the reserve region is not substantially deformed in case of a load on the upper part above the reserve region if the load is below a predetermined limit pressure, and that in case of a load above the predetermined limit pressure, the reserve region is deformed. A mattress having such a foam core is furthermore shown.

Ageing-resistant and low-emission mattresses and/or cushions comprising at least one section of flexible polyurethane foam, wherein the flexible polyurethane foam has been obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of the compound of the formula (I)

##STR00001##

and at least one blowing agent, are described.

A customizable sleep system includes a mattress, a mattress topper, and/or a pillow for accommodating the needed or desired body support and cooling of users. The system may include a mattress comprising one or more upper support members, each upper support member including multiple foam layers having at least one of different thermal conductivity characteristics and different glass transition temperature (Tg) characteristics and one or more lower support members, each lower support member including multiple foam layers having different support characteristics. The system may include one or more pillows each including multiple distinct foam layers differing in at least one of a support characteristic, a thermal conductivity characteristic, and a Tg characteristic. The system may include a mattress topper with one or more support members which each include multiple foam layers differing in at least one of a support characteristic, a thermal conductivity characteristic, and a Tg characteristic.

A flippable mattress includes a first memory foam layer, a second memory foam layer, a core layer disposed therebetween and a transition layer between each foam layer and the core. The first memory foam layer has a thickness, and the second memory foam layer has a thickness that is greater than the thickness of the first memory foam layer. The first transition layer has an IFD less than that of the second transition layer. The mattress is flippable between a first orientation in which the first memory foam layer is above the core layer and the second memory foam layer, and a second orientation in which the second memory foam layer is above the core layer and the first memory foam layer.

A mattress comfort system is disclosed. The mattress comfort system can include a mattress. The mattress can have at least one internal void into which a comfort member can be inserted through a mattress opening to fill the internal void.

It is disclosed foam mattresses or toppers, and methods of using them, comprising a top surface defining lateral deflective areas thanks to structural modifications of the foam comprising a plurality of slots, grooves, voids or channels. The invention (mattresses, toppers or methods) allows controlling postural alignment while providing ultra-low mattress-body interface pressures for all body areas regardless of recumbent position. The method comprises the step of providing into a core section of the mattress a plurality of structural modifications comprising slots, and/or voids, to form transversal deflective areas into the mattress. The invention is preferably achieved by CNC (Computer Numerical Control) cutting the structural modifications (channels, slots and voids) into the mattress foam which support each area of the body. It is also disclosed mattresses or toppers in which foam inserts are kept or removed from the channels to modulate the deflections on one or both sides of the mattress.

The present disclosure relates to a breathable cushion. The cushion includes a thigh support portion, a hip support portion, and a waist and back support portion. The thigh support portion includes a plurality of thigh support structures each having an opening structure; the hip support portion includes a plurality of hip support structures each having an opening structure; and the waist and back support portion includes a plurality of waist and back support structures each having an opening structure. The area of the opening structures of the thigh support structures and/or the area of the opening structures of the waist and back support structures is greater than the area of the opening structures of the hip support structures. The cushion has the following advantages. The cushion has an ergonomic design and structure, and provides reasonable and reliable supports. In addition, the light-weight and highly comfortable cushion has good air permeability.
