adapted to be readily folded along certain lines and particularly adapted for use in a foldin conch, whereby when said mattress is horizontally extended, it will have a substantially unbroken surface, and when folded, the surfaces of the sections'at opposite sides of the fold will be substantially at right angles to each other close to the fold;

and to provide a mattress of the usual box type, in which the box appearance is maintamed, although it is capable of being read ily folded.

An illustrative embodiment of this invention is shown in the accompanying drawings,

in which Figure 1 is a perspective View of a box mattress constructed according to this invention. Fig. 2 is a sectional view of the same, taken on the line A-A of Fig. 1. Fig. 3 is a corresponding section, showing the mattress in position upon a folding couch when the latter is in its folded or sofa position. Fig. i is a fragmentary section on the line B-B of Fig. 1..

lln the construction shown in the drawings, the mattress is of the usual box type, and comprises upper and lower coverings 1 and 2, spaced apart by edge strips 3. Before the mattress is filled with the padding material 4, the upper and lower coverings 1 and 2 are stitched or otherwise fastened together at 5 along the lines on which the mat tress is to be folded. This stitching extends throughout the greater part of the length of the mattress, but terminates a short distance from the ends thereof. The padding material is now filled in from the ends before the sewing of the edges of the end strips 3 is completed. Between each end of the lines of stitching 5 and 6 and the ends of the mat-tress, there is a marginal portion 7, which is filled to correspond to the full thickness of the mattress, thus preserving the box like contour, as may be seen from' Fig. 1. When the mattress is finished, the

lines of stitching 5 and 6 divide it into tions which in c'fibct are hinged together, and which can be readily folded at right angles to each other. The-marginal portions i, being comparatively narrow, do not prevent the free folding of the mattress.

This mattress is particularly adapted for use in folding couches, either of the type where the sides fold down against the frame, orof the type where one side folds down and the other up.

Fig. 3 of the drawings shows the mattress in position on the davenport style of folding couch, in which the side 8 is folded down against the frame, and the side 9. is folded up to form a back. This arrange ment avoids the common fault of this type of couch when fitted with an ordinary muttrcss, namely that when a person sits upon the seat section, there is a strain directed to the back section, which distorts it and renders it both uncomfortable andunsightly. The construction shown in the drawing gives a more elegant appearance to the couch when a cover is thrown over the mattress, since it insures sharp bends at the folds, and avoids bunching of the mattress, and the uncomfortable rounded bends of large radius occurring when the ordinary mattress is used.

ll amaware that mattresses have been made with their opposite faces stitched together by rows of stitches extending across the entire length or breadth of the mattress, but such sectional mattresses are objectionable for the reason that edges of the sections become rounded and form wide gaps in the surface along the rows of stitching where extended, rendering the mattress uncomfortable for use as a bed, and without the desired hoxlihe appearance. Such a divided mattress is also incapable of preserving a sharp angular fold adjacent to the outer faces of the sections, as illustrated in Fig. 3.

I claim 1. A box mattress, having a crease extending partially across it to provide folding sections, said crease being formed by bring I ing together and securing. the upper and lower coverings throughout a portion of their length, and means for preserving the box shape of the mattress at the endsof the creases, across the foldin sections.

2. A folding mattress, avin a crease extendin artially across it, sai crease being f0 y drawing the opposite coverings -'of said mattress together tooform said heattress into folding sections and being terminated inward of the ends of said mattress.

. v3. A folding mattress, having a crease extending partially across it, said crease being formed by drawing the opposite interme diate portions of the coverings of said mattress together and being terminated inward of the ends of said mattress, and said matings being stitched together at intermediate portions only to form a crease in the mattress extending partially thereacross when said coverings are stuffed, said side strips being continuous and of substantially full width across the ends of said crease, and means for supporting said side strips at the ends of the creases to preserve the box shape of the mattress at those points. 5. A folding mattress, comprising a plurality of integral sections, said sections being formed by stitching together the coverings of said mattress along a plurality of parallel lines extending partially thereacross, said stitching terminating inward of each end of said mattress, and said mattress having continuous uncreased marginal portions extending across the ends of said creases for the purpose specified.

Signed at Chicago this 30th day of December 1910.
