Various embodiments of the present invention address the limitations of traditional bed designs by providing additional length to existing beds and include bedframe extensions, boxspring/platform extensions, backer board, and mattress extensions, offering customizable solutions for individuals seeking enhanced comfort and space optimization, catering to various bed sizes and configurations. ## Claims ### Claim 1 An adjustable bed extension system comprising: a bedframe extension having two support beams and one or more crossbars connecting said support beams, wherein each of the two support beams includes an elongate horizontal portion and an elongate vertical portion, and wherein the one or more crossbars include an elongate horizontal portion, wherein the two support beams are configured to be connected to a head end or a foot end of a bedframe, the bedframe extension being independent and distinct from the bedframe; and a mattress extension that is independent and distinct from the bedframe extension and from the bedframe, the mattress extension having one or more surfaces that define an enclosed volume. ### Claim 2 (depends on 1) The adjustable bed extension system of claim 1, wherein each of the two support beams is L-shaped. ### Claim 3 (depends on 1) The adjustable bed extension system of claim 1, wherein the elongate horizontal portion is planar and the elongate vertical portion is planar. ### Claim 4 (depends on 1) The adjustable bed extension system of claim 1, wherein at least one of the elongate horizontal portion and the elongate vertical portion includes a plurality of spaced holes. ### Claim 5 (depends on 1) The adjustable bed extension system of claim 1, wherein the one or more crossbars include a plurality of spaced holes. ### Claim 6 (depends on 1) The adjustable bed extension system of claim 1, further comprising a boxspring extension sized to be supported on the support beams and the crossbars and disposed between the bedframe extension and the mattress extension. ### Claim 7 (depends on 6) The adjustable bed extension system of claim 6, further comprising a backer board attached to the bedframe extension. ### Claim 8 (depends on 7) The adjustable bed extension system of claim 7, further comprising one or more adjustable support legs attached to the bedframe extension and configured to support the bedframe extension on a support surface. ### Claim 9 (depends on 1) The adjustable bed extension system of claim 1, further comprising brackets attached to one end of each of the support beams. ### Claim 10 (depends on 9) The adjustable bed extension system of claim 9, wherein each of the support beams is adjustable using telescoping designs. ### Claim 11 (depends on 1) The adjustable bed extension system of claim 1, further comprising brackets attached to both ends of each of the support beams. ### Claim 12 (depends on 11) The adjustable bed extension system of claim 11, wherein each of the support beams is outfitted with a preexisting cutout. ### Claim 13 (depends on 1) The adjustable bed extension system of claim 1, wherein said boxspring extension is height adjustable. ### Claim 14 (depends on 1) The adjustable bed extension system of claim 1, wherein said mattress extension features a curve on one side of said mattress extension. ### Claim 15 (depends on 1) The adjustable bed extension system of claim 1, further comprising locking mechanisms for securing the position of said support beams relative to said existing bedframe. ### Claim 16 (depends on 15) The adjustable bed extension system of claim 15, wherein said locking mechanisms include one or more locking plates, and locking screws and bolts, nuts, or pins. ### Claim 17 (depends on 1) The adjustable bed extension system of claim 1, wherein the mattress extension is sized to be supported on the horizontal portion of the two support beams and on the horizontal portion of the one or more crossbars. ### Claim 18 (depends on 17) The adjustable bed extension system of claim 17, wherein the mattress extension is sized to be disposed between the vertical portions of the two support beams. ### Claim 19 An adjustable bed extension system comprising: a bedframe extension having two support beams and one or more crossbars connecting said support beams, wherein each of the two support beams includes an elongate horizontal portion and an elongate vertical portion, and wherein the one or more crossbars include an elongate horizontal portion; and a mattress extension that is independent and distinct from the bedframe extension, the mattress extension having one or more surfaces that define an enclosed volume, wherein the system is adaptable between first and second configurations, wherein, in the first configuration, the bedframe extension is attached to a bedframe and the mattress extension is supported on the bedframe extension, and, in the second configuration, the bedframe extension is detached and spaced from the bedframe and the mattress extension is spaced from the bedframe extension, wherein the bedframe is independent and distinct from the bedframe extension and the mattress extension.
