A rigid coupler having an upper surface, a lower surface and four sides, the coupler incudes a lower portion, an upper portion mateable with the lower portion, at least one inlet defined by the upper and lower portions, and at least one outlet defined by the upper and lower portions.

A mattress sheet stay apparatus for securing fitted sheets to a mattress includes an upper frame having an upper head portion, an upper foot portion, an upper left portion, and an upper right portion. The upper frame is configured to conform to a perimeter of a mattress. A lower frame has a lower head portion, a lower foot portion, a lower left portion, and a lower right portion. The lower frame conforms to the upper frame. A plurality of vertical sections is coupled between the upper frame and the lower frame. Each vertical section is configured to conform to a height of the mattress. Each of the upper frame, the lower frame, and the vertical sections have a high coefficient of friction.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.

A system and method of changing a sheet for a mattress of a bed is provided. More specifically, a bedding system includes a retention element sized to be retained on the mattress. A first bedding element is selectively interconnected to the retention system. Optionally, a second bedding element may be interconnected to the first bedding element. In one embodiment, at least one two-part closure interconnects the first bedding element to the retention element. In another embodiment, buttons interconnect the second bedding element to the first bedding element. In yet another embodiment, at least one two-part closure interconnects the second bedding element to the first bedding element. The two-part closure may be a zipper, a plurality of snaps, and a hook and loop system. In one embodiment, the retention element is removably interconnected to the mattress by at least one fastener or closure.

A bed frame connecting piece includes a first connecting piece connected to a horizontal rail of the bed frame and a second connecting piece connected to a vertical rail of the bed frame. A notch part is provided between the first connecting piece and the second connecting piece, and a reinforcing member is provided between the first connecting piece and the second connecting piece. The reinforcing member is located at the notch part and arranged at an inner end of the bed frame connecting piece. One end of the bed frame connecting piece is a narrow edge, the other end of the bed frame connecting piece is a wide edge, and the notch part is arranged at the wide edge. A bed frame includes the above bed frame connecting piece.

A fitted mattress cover is provided, having elastic elements at each corner which hold the cover in place. A corner elastic element runs along each corner seam, and is attached to the center of a diagonal elastic element. The diagonal elastic acts a lock system to prevent movement of the fitted sheet during any pull from the top of the fitted sheet. The corner elastic helps to hold the corner of the cover to the mattress, and also prevents peaking of the corner seam, leading to an improved appearance and helps to fit mattresses of different thickness. Elbow elastics at the corners, perpendicular to the corner elastics, hold the side panels tightly to the mattress and inhibit them from sliding upwards.

A passive mattress spacer pad provides an intermediate layer of material which sits between the bottom of the mattress and the underlying mattress support. In some embodiments, the spacer may have peripheral length and width dimensions that are roughly between about 1 and 18 inches smaller than the size of the mattress and have a thickness of between about inch and about 4 inches. In some embodiments, the spacer pad is independent, and in others, it is integrally formed with the support or the mattress. The spacer provides a measure of lift or elevation to the center of the mattress while leaving some space or gap around the peripheral edges where it is easier for the bed maker to slide their hands and the bed linens beneath the mattress edge without having to lift the mattress entirely.

A sheet retainer to retain a sheet fitted onto a bed in a wrinkle free or taut condition is disclosed herein. The sheet retainer includes a base member, a rail member, and a grip member. The rail member extends vertically from at least a portion of an end of the base member. The base member is placed beneath a corner edge of the mattress securing the bed sheet and pushed or butted against the rail member to maintain the bed sheet onto the mattress in a taut position. The base member includes a textured surface to retain the bed sheet fitted onto the mattress in the taut condition and prevent dislodging of bed sheet from the mattress. Advantageously, the sheet retainer holds the bed sheet tucked beneath the mattress in taut condition without causing damage to the bed sheet, or to the user during use.

A gather-fitted bedding placement apparatus and method for easy installation and removal, and prevention of slippage during use, of gather-fitted bedding upon a bed mattress. The apparatus has a semi-flexible friction-calibrated sheet-material unit of a size corresponding to the standard minimum depth of the bed mattress, a bottom lip formed along the bottom edge of the semi-flexible friction-calibrated sheet-material unit, at least one curve-enabling notch in the central portion of the bottom lip, to enable bending of the semi-flexible friction-calibrated sheet-material unit to conform to the corner of the mattress, a bottom-lip curved-corner portion formed by such bending, and at least one tab cutout through the semi-flexible friction-calibrated sheet-material unit. The method is practiced by using a gather-fitted bedding placement apparatus at each corner of the mattress, placing the bent semi-flexible friction-calibrated sheet-material unit underneath and inside of a corner of the gather-fitted bedding, with the gathered edge of the bedding wrapped around the bottom lip and the bottom-lip curved-corner portion, with the gathered edge resting on the top or inner surface of the bottom lip and the bottom-lip curved-corner portion, manually pushing the semi-flexible friction-calibrated sheet-material unit and the fitted bedding downward over the bed mattress for installation, or manually pulling upward for removal, using the tab cutouts or the bottom lip as gripping points, where the low-friction inner face of the semi-flexible friction-calibrated sheet-material unit provides smooth downward and upward pushing for installation and removal, and the bottom lip and the bottom-lip curved-corner portion hold the gather-fitted bedding in place underneath the bed mattress during the period between installation and removal.
