A body support structure includes a molded polymeric support grid having a three-dimensional molded contour. The support grid includes a body support region having a plurality of through openings separated by a plurality of lands. In one embodiment, an area of the openings is greater than an area of the lands. In another embodiment, the ratio of a surface area of the lands relative to an area defined by an outer peripheral edge is less than or equal to 0.74. A fabric layer is bonded to the plurality of lands and covers the plurality of openings. Methods of manufacturing and recycling the body structure are also provided.

An element molded from a particle foam, including for example expanded polypropylene foam, includes at least one visible exterior surface defined by the particle foam. The visible exterior surface is textured having a roughness depth of less than or equal to 1.00mm and a plurality of vent interfaces each having a maximum width of less than or equal to 0.4mm. Methods of molding the element, together with a mold and a method of making the mold, are also provided.

A body support structure includes a body support member and a base having an upper component coupled to the body support member and a lower component adapted to be supported on a floor. An adjustable spring mechanism biases the body support member. A weighing mechanism is coupled to the adjustable spring mechanism. The weighing mechanism includes a height adjustment device disposed between the upper and lower components of the base. The height adjustment device includes a pneumatic spring having a pressure tube coupled to the lower component and a piston rod extending upwardly from and moveable relative to the pressure tube. A housing is disposed around the pneumatic spring and is coupled to the upper component. An adapter is coupled to the piston rod. A weighing spring is disposed between the adapter and the housing, with the housing moveable relative to the adapter between first and second weighing positions.

A load support member includes spaced apart beam members, a linking member and a stop member. In another aspect, the beam includes a support surface defining first and second landing regions, which are in contact with and support a membrane. In another aspect, a brace member is secured between laterally spaced beams, with the brace member having a greater height than width at the end thereof and a greater width than height at the middle thereof. In another aspect, a pair of armrests are joined to a cross member and a pair of spaced apart beams in a releasable engagement. In yet another aspect, a pair of beam members are fixedly joined with a cross member, which is pivotally connected to a link pivotally connected to the beams. A method of assembling a load support structure is also provided.
