Abstract
Abstract A guard constructed of plastic-clad wire has a horizontal portion captured beneath the corner of a box spring, and vertical portions extending upwardly adjacent the sides of the box spring and a mattress lying thereon. The vertical portions prevent the mattress from sliding over the edges of the box spring at the corner; use of four such guards, one at each corner, immobilizes the mattress and keeps it properly aligned with the box spring. A brace portion is affixed over the box spring to clamp the guard to the box spring and to stiffen the vertical portions of the guard. A second horizontal portion is formed about the corner of the mattress between the ends of the vertical portions to further stiffen the assembly and to assist in retaining the mattress in position.

Claim 1
Independent Claim
147 words
A mattress guard for aligning a mattress with a box spring thereunder, each of said mattress and box spring having vertical sides and corners, and said box spring having at least two edges resting upon a support thereunder, the guard comprising: a horizontal portion adapted to be captured between said box spring and said support thereof at one of said corners of said box spring, said horizontal portion extending beneath said box spring from a first side to a second, adjacent side thereof; and a pair of vertical portions secured at lower ends thereof to said horizontal portion at said first and second sides of said box spring, each of said vertical portions extending upwardly to ends adjacent said sides of the mattress, whereby said guard prevents said mattress from slipping outwardly past either of said first and second sides of said box spring at said corner.
Claim 2
Dependent Claim
147 words
A mattress guard for aligning a mattress with a box spring thereunder, each of said mattress and box spring having vertical sides and corners, and said box spring having at least two edges resting upon a support thereunder, the guard comprising: a horizontal portion adapted to be captured between said box spring and said support thereof at one of said corners of said box spring, said horizontal portion extending beneath said box spring from a first side to a second, adjacent side thereof; and a pair of vertical portions secured at lower ends thereof to said horizontal portion at said first and second sides of said box spring, each of said vertical portions extending upwardly to ends adjacent said sides of the mattress, whereby said guard prevents said mattress from slipping outwardly past either of said first and second sides of said box spring at said corner.
