Abstract: A coil spring comprises a continuous wire forming a lowermost convolution, an uppermost convolution, and a plurality of helical intermediate convolutions. The coil spring is divided into an upper portion and a lower portion. The intermediate convolutions of the lower portion have a diameter greater than or equal to a lower minimum diameter, and the pitch between each of the convolutions of the lower portion is greater than or equal to a lower minimum pitch. The intermediate convolutions of the upper portion have a diameter greater than or equal to an upper minimum diameter, and the pitch between each of the convolutions of the upper portion is less than or equal to an upper maximum pitch. The upper minimum diameter is greater than, less than, or equal to the lower minimum diameter, and the upper maximum pitch is less than the lower minimum pitch to provide a non-linear and variable response.

Abstract: A support cushion for providing individualized heating and cooling to a user resting on the support cushion is provided. The support cushion includes a body supporting layer and an air distribution layer positioned adjacent to the body supporting layer. The air distribution layer includes a base plate and foam rails positioned at least around a perimeter of the base plate to define a cavity with a support insert positioned within the cavity. A fan is operably connected to the air distribution layer and provides air flow into the cavity of the air distribution layer. Air flow is directed through the support insert and into and through the body supporting layer.

Abstract: A hybrid pillow includes a cushion material defining a recess. A coil panel is positioned within the recess of the cushion material with the coil panel formed of a plurality of coil springs, an upper fabric layer, and a lower fabric layer. The upper fabric layer and the lower fabric layer are joined between the plurality of coil springs and along peripheral edges of the first coil panel. A gel layer is also positioned within the recess of the cushion material and over the coil panel. A method of manufacturing the pillow includes dispensing a liquid gel in a mold, positioning a coil panel in the mold and on top of the liquid gel, dispensing a foam precursor in the mold, and foaming the foam precursor to form a cushion material that is secured to the coil panel.

Abstract: A hybrid pillow includes a first coil panel and a second coil panel which are joined along peripheral edges to form an inner shell defining a gap therebetween. The first coil panel is formed of a plurality of coil springs, an upper fabric layer, and a lower fabric layer, with the upper fabric layer and the lower fabric layer joined between the plurality of coil springs and along peripheral edges of the first coil panel. The second coil panel is formed of a second plurality of coil springs, a second upper fabric layer, and a second lower fabric layer, with the second upper fabric layer and the second lower fabric layer joined between the plurality of coil springs and along peripheral edges of the second coil panel. A support material disposed in the gap of the inner shell, and one or more additional layers disposed about the inner shell.

Abstract: Present embodiments provide various open coil spring assemblies which perform like an encased spring assembly. The embodiments have elastic lacings or connections which connect springs to springs or springs to lacings. Various spring embodiments are provided as well as various arrangements for the elastic lacings. All of these features improve compliance and stability while reducing motion transfer.

Abstract: A spring core is provided that includes a plurality of coil springs having an upper portion and a lower portion that collectively define an interior cavity. The spring core further includes a continuous upper fabric layer that covers each coil spring and defines a recess in the interior cavity of each coil spring. A cushioning layer is positioned atop the continuous upper fabric layer and extends into the recess in the interior cavity of each coil spring. A mattress assembly is further provided that includes the spring core, an upper body supporting layer, and a lower foundation layer. Methods of producing a spring core are further provided.
