Description

t t r~ BE ~ FIELD OF INVENTION The present invention relates to mattresses for beds.
BACKGROUND TO INVENTION The conventional type of mattress is of rectangular shape having two elongated side edges and two end edges defining a substantially flat support surface between these edges.
Such a mattress often is uncomfortable to lie on.
It is an object of the invention to suggest another type of mattress which offers certain features of greater comfortability.
SUMMARY OF INVENTION According to the invention, a mattress comprises a body of resilient, compressible material and including two end edges and two side edges as well as a bottom face and an upper face; two elongated ridges, one of each extending along each side edge; and a channel provided in the upper face extending between the two ridges.
The channel may be of curved concave shape in end view.
The ridges may be of semi-circular shape in cross-section.
The ridges may be substantially parallel.
The body may be made of polyurethane foam material.
BRIEF DESCRIPTION OF DRAWINGS The invention will now be described by way of example with reference to the accompanying schematic drawings.
In the drawings there is shown in Figure 1 a pictorial view of a mattress in acccrdance with the invention; Figure 2 a front view cf a bed provided with a matress as illustrated in Figure 1; and Figure 3 a side view seen along arrow III in Figure 2.
DETAILED DESCRIPTION OF DRAWINGS.
Referring to the drawings, a mattress in accordance with the invention is generally indicated by reference numeral 10.
The mattress has a mattress body 12 made of resilient, compressible material, such as polyurethane material.
The mattress 10 includes two end edges 14, 16 and two side edges 18, 20. It further has a bottom face 22 and an upper face 24.
A channel 26 is provided in the upper face 24 and extends between the two side edges 18 and 20. The channel 26 is defined by two spaced apart elongated ridges 28, 30 respectively located adjacent the side edges 18, 20.
The channel 26 is of curved concave shape in end view.
The ridges 28, 30 are of semi-circular shape in cross-section seen in end view and are substantially parallel.
The mattress 10 may be supported on a bed structure 32 including a base panel 34 and legs 36.
A person would, when lying on the mattress 10, be supported on the curved central intermediate area of the channel 26 and the ridges 28, 30 would support the sides of the body of the person. Such curved central support and side support ridges in most instances has been found to be very comfortable and assist in relieving any strain on the body.
