The slats 21 are thus held in spaced relation throughout the width of the mattress and in spaced relation by transverse strips 28 which may be secured to the slats in any suitable manner as, for example, by tacks or nails 29, Fig. 4.

The outer or extreme side slats 30 and 3 I, Figs. 2 and 4, are edged by a strip 32 of resilient material, such as foamed or cellular avoiding a hard surface. The outer face 'or edge of this strip may be thus positioned in vertical alignment with the longitudinal rails 33 in a manner similar to the positioning of a box spring of the construction heretofore used. The entire supporting structure may be inclosed in a cover 34 of ticking-or other suitable fabric which may be made to cover the upper surface of the slat assembly and all surfaces of the resilient blocks 25 and 26.

It will be apparent fromthe above that each of the slats 21 may be depressed independently at the pressure on each slat tire construction, however, forms a unitary structure which may be readily lifted and is particularly light because it consists of the-slats which may be made of wood or light metal, and of the resilient blocks which are relatively light because of their porosity and also because they extend only throughout a limited supporting area of the structure.

In the modification shown in Figs. 5 and 6, the arrangement of slats and of the resilient supports or bolsters is similar to that of Figs. 1 to 4, but there is also provided a rail 35 embedded in the resilient supports 25 and 26, as indicated in Fig. 6, and extending above and resting on the side rail 33 of the bed frame.

The cover 34 is extended downwardly as at 36 from the resilient strip 32 and about the rail 35 so as to form a smooth vertical wall or surface in a1; cut with the outer face of the bed frame rail 3 over for storage or transportation.

In the modification shown in Fig. 10 the supporting structure is made in two halves 40 and 4| which are in mirror relation to each other as shown in Fig. 9

with ticking or other material 58. With this construction it is only necessary to turn the end of the ticking over the edges of the slats and tack it in place.

Through the above a mattress support of a simple, light, convenient which, therefore, provides the effect of great depth and softness.

What I claim is:

1. A supporting structure for mattresses which comprises a number of spaced parallel slats and common supporting blocks of molded cellular rubber for said slats, said slats being individually embedded in said blocks.

2. A supporting structure for mattresses which comprises a number of spaced parallel slats and 01' said slats and said slats being secured to said bolsters.

7. A support for mattresses which comprises spaced transverse bolsters of resilient cellular rubber and spaced longitudinally extending yieldable slats supported on and partly embedded in said bolsters to form a substantially continuous flat supporting surface for a mattress.

8. A support for mattresses which comprises spaced transverse bolsters of resilient cellular rubber and spaced longitudinally extending yieldable slats supported on and partly embedded in said bolsters to form a substantially continuous flat supporting surface for a mattress, and strips extending across and connecting said slats.
