3 Claims.

The present invention relates to cushioned sleeping, seating or lounging structures, and has particularly to do with an improved mattress and cushion construction.

As the structure is particularly applicable to a mattress, the objects of the invention and" the description hereinafter given will be directed primarily to mattress structure, but it will be evident that the description and claims will be equally applicable to cushions, and to numerous other devices.

Mattresses of the ventilated type have recently been adopted as highly desirable but have been exceedingly cold in the winter time. The

cold air which is admitted to every well regulated sleeping room, seeps into the mattress, and chills the interior through the ventilating pores. There is insumcient protection between such cold air and the sleeper to permit the body tov heat the bed sufficiently for the sleeper to remain warm- The sleeper ordinarily piles more covers on top but this does no good because the air is from beneath. The body heat is dissipated through lack of insulation or by radiation.

To overcome this serious objection to ventilated mattresses and cushions, which are generally combinations of upholstery or padding and springs, is the primary object of the present invention, such object being to produce in a venl tilated mattress or cushion structure means for insulating at least one supporting surface of the mattress or cushion against the cold air which may circulate therethrough. A second object of the invention is to provide a mattress having insulation at one side and free frominsulation at the other side so that the mattress may be reversed for summer and winter use and yet maintain the sleeper comfortable the year round.

A further object of the invention is a new and improved structure for mattresses and cushions. These objects, and such other objects as may hereinafter appear, are obtained by the novel construction, unique arrange'nientand improved combination of the several elements which constitute the one form of the invention illustrated, that being a mattress. In the drawing illustrating such invention:- Figure 1 is a plan view of a mattress, a portion of one supporting surface being broken away to show the, spring .structure;\ and Figure 2 is a fragmentary sectional perspective 1 of one corner, of the mattress illustrated in Figure 1. v

" Like reference characters are used to designate similar parts in the drawing and in the description of the invention which follows.

The mattress illustrated, and this would be the same in respect to a cushion, comprises a central or core portion 10 made up of a plurality of springs, spiral or coil in character, 11, suitably joined or tied together by attachment to frame strips, not shown, or in any other conventional way.

Over the spring core 10 there is a suitable sheeting or covering 13. In order to make a mattress which will at all times permit of circulation of air through the core, but which will insulate the sleeper from such air in the winter while allowing the air to circulate freely in the direction of the sleeper in the summer time, the spring cover may be divided into two sections, that designated 12 in the drawing being of insulatory material such as a silk, rubber sheeting or a specially treated fabric possessing high insulating qualities, uch material should be incapable of radiating heat, as well as a poor conductor thereof. The sheeting 13, adjacent the insulating sheet 12 is partof the usual mattress structure which permits of the free circulation of air therethrough. Where an insulate sheet 12 is employed, the sheeting 13 may be omitted.

The core 10 at its opposite side is covered by the sheeting 13, and is upholstered with the customary padding 14. The padding 14 is covered by a ticking 15 and tacked at 16 in a conventional way. The sides of the mattress may have a covering 18 of material like 15. Longitudinal stitching 19 may be employed to keep the padding at the side in proper position and in an even layer.

Through the sides 18 there may be any suitable ventilator opening, such as that shown at 20 in Figure 2. Such openings 20 may be arrs. ed in spaced relationship about the side of the mattress.

Modifications of the structure described to adapt it for automobile cushions, airplane seats, and to lounging surfaces are perfectly apparent. In such devices, where there'is but onecontacting surface, the material above the springs, of course, should be of insulatory and non-radiating character. Such insulatory material should be suflicieiitly sturdy or tough to stand the wear of the springs 11 thereagainst.

The mattress structure described permits of a free circulation of air through the springcore 10 while insulating the body of the user from such cold air when that is desired. In the case of a mattress providing two sleeping surfaces of a tween the springs 11 and the padding 14 thereabout so long as such membrane is of sufficient structural strength to not readily wear and so long as it is impervious to the passage of the air or is such a poor conductor and radiator of heat as to retain the heat of the body in the padding 14 and not dissipate it into the air space around the springs 11.

In Figure 2, the lower side of the mattress discloses a noninsulatory covering 13 for the spring section while the upper side of the mattress includes the insulatory covering 12 in combination with the noninsulatory covering 13 whereby the insulating material 12, generally of less strength than noninsulating material 13, is protected from the wear and tear of the springs upon the surface thereof.

I claim:

1. A mattress or the like of cushioning layers to provide a padded section at each side thereof, springs between said cushioning layers, a heat cushioning layer, and a ventilating cover over said springs, and cushioned layers, the ventilating portions in said cover being in the section thereof intermediate said cushioning layers.

3. A mattress or the like having cushioning layers to provide a padded section at'each side thereof, springs between said cushioning layers, a noninsulatory membrane intermediate said springs and one of said cushioning layers, an insulating membrane between said springs and.

the opposite cushioning layer, a noninsulating membrane in association with said insulating membrane and intermediate said insulating membrane and said springs, and a cover over said springs, said insulating membrane, said noninsulating membranes, and cushioned layers, and

having ventilating ports in the section thereof intermediate said cushioning layers.
