WIPO Patent Application WO/2022/116557

A1

The present invention provides a foldable and rollable partitioned spring mattress, which comprises a partitioned spring layer; the partitioned spring layer is provided with a first lateral region, a second lateral region, and a third lateral region; a centerline of the mattress passes through the second lateral region; the first lateral region is disposed between the second lateral region and the top part of the mattress; and the third lateral region is disposed between the second lateral region and the bottom part of the mattress. The second lateral region contains pocket springs having individual metal coils, and each metal coil is wrapped within a cloth bag. The first lateral region and the third lateral region comprise coils connected one to one by means of parallel rows of spirals, and the spirals extend in the direction perpendicular to the centerline. After being compressed, the mattress is folded along the centerline thereof located on the pocket springs of the second lateral region, and then the compressed and folded mattress is rolled, without folding or bending the spirals. The package size of the partitioned spring mattress of the present invention is smaller and is more suitable for express parcel delivery systems and standard shelf spaces of retailers.
