Abstract: A mattress assembly includes a tub including rails and a base with the tub defining an interior cavity bound by the rails and the base, a plurality of non-laminated and rearrangeable layers positioned within the interior cavity to provide both support and comfort levels within the mattress assembly with each layer including at least one of a layer cover or a layer foam, and a cover system including a removable cover allowing selective access to the plurality of layers and the interior cavity and selectively compressing the plurality of layers within the tub, where the cover system includes a first zipper and a second zipper coupling the removable cover to the tub, and the first zipper and the second zipper meet at a central portion of a front side of the mattress assembly.

Abstract: Systems and apparatuses include a mattress assembly including a tub including vertically extending rails and a base and defining an interior cavity bound by the rails and the base, a plurality of non-laminated and rearrangeable layers positioned within the interior cavity to provide both support and comfort levels within the mattress assembly, each layer including a layer cover and a layer foam, and a cover system that includes a removable cover allowing selective access to the plurality of layers and the interior cavity and selectively compressing the plurality of layers within the tub.

Abstract: A locking device for securing and positioning an object when it is strung on a line by a through-hole of the object. The locking device includes an elongated shaft defining a partial cavity formed therein. The elongated shaft or a deepest portion of the partial cavity or both is tapered relative to a longitudinal axis of the shaft. The partial cavity extends along the longitudinal axis of the shaft, and the deepest portion of the partial cavity and the exterior surface of the elongated shaft forms a tapering angle. The locking device is inserted into through-hole of the object such that the rope or line fits into the partial cavity. Pressure may be applied to put the locking device into the through-hole such that there is no movement between the object and the line; thus securely positioning the object on the line. The locking device may be used to securely position a through-hole type boat fender on a line.

Abstract: The present invention comprises a fluid pressurizable multiple chamber mattress wherein one or more chambers is capable of operably receiving and releasing a fluid. The mattress has a first and/or a second fluid pressurizable chamber, which may include material, defined between the outer surfaces of the fabric layers.

Abstract: The present invention comprises a fluid pressurizable multiple chamber mattress wherein each chamber is capable of operably receiving and releasing a fluid, comprising a first covering sheet, at least two fabric layers positioned upon the inner surface of the first covering sheet, the inner surfaces of the fabric layers being linked via a plurality of threads, a second covering sheet, a first dielectric weld forming a first and a second fluid pressurizable chamber defined between the outer surfaces of the fabric layers and the inner surfaces of the first and second covering sheets, a second dielectric weld, forming a third fluid pressurizable chamber defined between the inner surfaces of the first and second covering sheets and the inner surfaces of the fabric layers; and at least one fluid valve carried by at least one covering sheet for permitting the pressurization and depressurization of at least one fluid pressurizable chamber.
