It is therefore an object of the present invention to pro
vide an improved mattress having enhanced support in 30
the area of the small of the back of the user.
Another object of the invention is the provision of a
to provide cushioned surfaces at the top and bottom sur
faces of the mattress. Padded side panelling 31 is then
secured -about the .side surfaces of the core and the entire
structure is covered and tied together by means of tick

It will be appreciated that the mattress construction
so far described is substantially conventional. As pointed

supporting characteristics and a materially extended life.
Still another object of the invention is to provide a
mattress of double lbed size which has strengthened back

in mind, I have minimized fthe sagging tendency in the

provision of strengthened supporting sections in the re
