A portable mat capable of blocking air convection and temperature radiation is disclosed. The portable mat is an inflatable mat, and includes a first outer covering layer and a second outer covering layer that are connected by a plurality of connecting members each in the form of a thin and light ring. Side pieces of the connecting members each have different widths according to high and low positions. A plurality of blocking layers of a blocking unit is fitted on the connecting members. The block layers have openings with different widths. The openings of the blocking layers are different in size corresponding to the different widths of the connecting member, so that the blocking layers are positioned at different heights to form a plurality of spaced space inside the mate, thereby blocking air convection and reducing temperature radiation.

A nonwoven fabric used for a foamed article reinforcing material to be bonded to a foamed material to reinforce the foamed article is a single-layer material in which stacked layers of a web are bonded together, has a thickness of 1 to 8 mm under a load of 7 g/cm.sup.2, and has a delamination strength of 0.05 to 2.45 N/cm. The delamination strength is a value of the pulling force required to peel the bonded layers of the web apart.

An inflatable bed is provided. The inflatable bed comprises a top sheet and a bottom sheet disposed vertically at an interval, at least one side wall, at least one first tensioning structure and at least one support structure. An upper edge of said side wall is coupled to an outer edge of said top sheet. A lower edge of said side wall is coupled to an outer edge of said bottom sheet. An upper end and a lower end of said first tensioning structure are respectively coupled to said top sheet and said bottom sheet. Said support structure is disposed in a longitudinal direction of at least one of said side walls. At least two outside edges of said support structure are respectively coupled to the side wall adjacent. At least one inside edge of said support structure is coupled to the top sheet or bottom sheet adjacent.

Steps for using an insert to restore sagging sofa cushions are provided. Over time, the cushion develops a depression on a sitting surface of a deformable member and an elevation on a base surface of the deformable member. The cushion also suffers from reduced elasticity in the deformable member. Positioning the insert between a cushion casing and deformable member of the cushion allows for sagging areas of the cushion to be fixed. The cushion restoring insert thus addresses both aforementioned issues. An elongated elastic member with similar elasticity to the original cushion provides a like-new level of elasticity for the cushion. The cushion restoring insert also increases volume within the cushion casing, causing tension in combination with the cushion casing. This tension counteracts the depression and elevation, helping to return the cushion to a like new state.

A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a base and a litter supported by the base via a lift system. The litter comprises a seat section and a foot section movable relative to the seat section. The lift system comprises lift members. The lift system moves the litter from a first configuration in which the seat and foot sections are generally horizontal relative to a floor surface to a second configuration where the foot section is below the seat section and between the lift members. The patient support apparatus also comprises a mattress assembly integrated with the foot section to move with the foot section between the first and second configurations.
