A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

A mattress includes a layer including a first surface and a second surface arranged opposite to the first surface. The layer defines a plurality of slits extending from the first surface to the second surface and arranged in a plurality of rows extending in a longitudinal direction. The slits in each row are arrayed linearly in the longitudinal direction and are disposed spaced apart from each other. The rows of the slits restrict a compression of the layer to an area under loading and prevent the surrounding portion of the layer from being pulled towards the area under loading.

A pocket spring mattress for use in a bedding or seating product is disclosed. The mattress comprises a plurality of interconnected coil springs enclosed in continuous covers forming strings of pockets accommodating the coil springs. Adjacent coil springs within each string are spaced apart by an interjacent separation distance, said separation distance exceeding at least 20 percent of the diameter of the largest one of the spiral turns of the adjacent coil springs. Further, the pocket spring mattress further comprises a cushioning pad located above the upper end of each coil spring, wherein the covers provides first compartments enclosing the coil springs, and second compartments enclosing the cushioning pads, said first and second compartments being separated from each other. The cushioning pads each have a length extension in the longitudinal direction of the strings exceeding the diameter of the largest one of the spiral turns of the corresponding coil spring.

A three-layered topper for a bedding or seating product has a first piece of foam, a second piece of foam and a pocketed spring comfort layer therebetween. The pocketed spring comfort layer has individually pocketed mini coil springs. At least one of the foam pieces may be infused with metallic particles to improve thermal conductivity. Alternatively, at least one of the foam pieces may be infused with microencapsulated phase change materials to improve heat absorption. At least one of the foam pieces may have a coating to further improve thermal conductivity or heat absorption.

A mattress having a flange construction for securing a border assembly is disclosed. The flange construction is formed of a material that is affixed along the perimeter of an upper surface of the mattress. The border assembly includes a flap material for binding the border assembly to the flange construction. The flap material may be adhered to the flange construction, thereby allowing the flange construction to anchor and secure the border assembly to the mattress.

A side rail assembly and a mattress assembly including the side rail assembly about at least a portion of a perimeter of the mattress assembly. The side rail assembly includes a laminate structure including one or more foam layers and one or more fiber layers in a stacked arrangement. The fiber layer can be a non-woven layer.
