A method of installing an array of linear foam strips designed to be vertically stacked with their linear axes parallel and vertically aligned under a region of a mattress that requires a raised contour on its top face to alleviate a medical condition or to repair a sag in the mattress. The foam strip arrays come in 24 or 32 inch lengths to correspond to the width of standard mattress. Each linear foam strip has a different width but none of the strips are within 25% of the width of any other foam strip. The widths of the four different foam strips in the array has been carefully sized to allow the best possible combinations to develop the proper height and side slope of the contour developed in the mattress's top face.

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 system. The mattress system including a foam mattress having a plurality of stacked layers, wherein each of the stacked layers has a top surface and a bottom surface thereby defining a plurality of interstitial pockets and one or more rigid plates configured to be inserted into the one or more plurality of interstitial pockets, thereby enabling the mattress system be selectively optimized to provide a desired structural support and firmness for a user's body type and weight.

An outdoor sleeping mat and a sleeping mat set includes a sleeping mat main body, a plurality of transverse supporting belts and a plurality of vertical supporting belts. The sleeping mat main body has a cavity, and the transverse supporting belts and the vertical supporting belts are disposed in the cavity and connected to the sleeping mat main body. The plurality of vertical supporting belts are distributed at two sides of the sleeping mat main body in a width direction, and the plurality of transverse supporting belts are arranged side by side in a length direction of the sleeping mat main body. The outdoor sleeping mat enhances the structural reliability of the sleeping mat main body through the plurality of transverse supporting belts and the plurality of vertical supporting belts, so that the whole outdoor sleeping mat has better supporting performance.
