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 a base layer positioned adjacent to and below the body supporting layer. The base layer defines a cavity with a support insert positioned within the cavity. The support insert includes a bag defining one or more outlet holes positioned adjacent to the body supporting layer and further defining an inlet hole. A fan is operably connected to the inlet hole of the bag to provide air flow into the inlet hole of the bag and out of the one or more outlet holes of the bag. Methods of controlling the surface temperature of a support cushion are also provided.

Abstract: A pillow is provided that includes a latex foam to provide comfort and support to the body of a user. The pillow includes a latex foam layer connected to at least one additional foam component. An internal foam layer is also included in the pillow, with the latex foam layer and the additional foam component disposed about the internal foam layer.

Abstract: A coil-in-coil spring is provided that exhibits a variable and non-linear loading response. The spring includes a first spring portion having a first spring constant, a second spring portion having a second spring constant less than the first spring constant, and a third spring portion having a third spring constant less than the first spring constant and less than the second spring constant. The first spring portion forms an outer coil of the coil-in-coil spring and the second spring portion, the third spring portion, or both the second spring portion and the third spring portion are positioned within the first spring portion and form an inner coil of the coil-in-coil spring. A multi-coil spring is also provided that includes an outer coil, an intermediate coil positioned within the outer coil, and an inner coil positioned with the intermediate coil.

Abstract: A spring is provided that exhibits a variable and non-linear loading response upon compression. The spring comprises a continuous wire having a lower end convolution, an upper end convolution, and a plurality of helical intermediate convolutions. The upper end convolution, the lower end convolution, and the helical intermediate convolutions each have a respective diameter, with the continuous wire further defining a pitch between the various convolutions. In the spring, one or more of the diameters of the convolutions or one or more of the pitches varies along the length of the continuous wire such that the spring exhibits a non-linear loading response upon compression. A mattress is further provided and includes a plurality of the springs arranged in a matrix.

Abstract: Air conditioned mattresses have a core and at least one encasement configured to receive a conditioned flow of air into the encasement and to allow conditioned air to flow out of the encasement to a sleep surface of the mattress. Additional conditioned air conducting layers are provided in combination with the encasement.

Abstract: A pocketed spring, such as that used in a mattress, comprises: a compression spring having an upper end convolution and a lower end convolution opposite the upper end convolution, and a plurality of helical intermediate convolutions between the upper end convolution and the lower end convolution; a flexible enclosure including a top wall positioned adjacent to the upper end convolution of the compression spring, a bottom wall positioned adjacent to the lower end convolution of the compression spring, and a side wall that extends from the top wall to the bottom wall; and a tension member connected to the flexible enclosure. The tension member acts in opposition to the compression spring until the pocketed spring is compressed to a point at winch the tension member no longer applies any force. Thus, the pocketed spring exhibits a non-linear response when compressed.
