4 Claims. 1

YThisinvention* relates to' mattresses, and more particularly to a mattress construction by means of which units may befselected to provide in one mattress sections of different resilient properties so that where persons of; substantially different weightsare: sleeping, side, by side, there will be no undue depression'. of: one side ofthe mattress due to the heavier weight ofthefoccupant, thereby improving the comfort of both persons.

A further object of the invention is to provide an improved-mattress bywmeans of which its principal component parts. can` be: readily inspected and, if desired, alternated or shifted to suit circumstances and increase the comfort of the occupants.

A furtherobject'is to provide an improved mattress structure in which the padding material is most eiTectively used" for the comfort of the occupants, and the completereversal of the mattress is unnecessary.

Variousother objects willmore particularly appear in the course of the following detailed description.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more particularly described and claimed.

Two sheets of drawings accompany this specication as part thereof, in which like reference characters indicate like parts throughout,

Referring to the drawings:

Figure 1 is a perspective view of the improved mattress with the cover top partly turned back at one corner;

Figure 2 is a perspective view of the improved mattress with the cover top rolled back to the head of the mattress;

Figure 3 is a perspective view showing the cover and the resilient pads partly rolled back; and

Figure 4 is a transverse vertical cross section taken on line --4 of Figure 1.

Where two persons of substantially different weights sleep on the same mattress, as in a double bed, inconvenience and discomfort frequently arise by reason of the disposition of the mattress to settle under the person of greater weight, thereby causing the remainder of the mattress to assume an angle and making it difficult for the lighter person to retain his proper position.

To eliminate this diiculty, I propose constructing the mattress of a plurality of independent elements which may be selected with the weights of the occupants in mind, and which can by arrangement in a vcommon cover of the box type, provide comfortable support to both occu- 2, pants of the-bed, while at the same time the-mattress as an entirety-will maintain a substantially horizontal upper surface.

In one desirable embodiment of'the'invention illustrated in the-i accompanying drawings,- the mattress cover is shown as of the popularbox type comprising a top I, bottom 2- andperipheral wall structure 3, the'wall 3-fbeing'divided intermediate the top and Vbottom and removably-secured at the foot and on the two sides by a slide fastener ofthezipper-typeindicatedat 5. Such a cover, it Willbe noted, will hinge onthe fourth or head side, thuspermitting ready accessA tothe interior.

Within the cover are positioned twoA spring units 9 and' I0, each comprising aplurality cf'coilsprings. It will be\ understood; that the coil springs utilizedin the-unite will be, for purposeof illustration, rmer thanv the springs-utilizediin the unit IB, but preferably all-of the springs in the unit 91 will be ofy uniform strength and all' of the springsr in unit IU willi beA of. uniform strength.

IThe springs of each unit are interconnected in any desirable manner, herein illustrated as by transverse coil springs I2 secured to each of the various rows of coil springs in each spring unit and each of the spring units 9 and i0 is provided on its upper face with a padded cover I I.

Positioned over each of the spring units 9 and IS are resilient pads l' and 8 of sponge rubber or similar material, and preferably these resilient pads will also be of different resilient properties so that a more delicate adjustment of the mattress can be made if desired, by shifting one of the elastic pads over one or the other of the spring units, as desired.

The top of the mattress cover I is preferably provided with a uniform pad 6 coextensive to the entire mattress and secured to the mattress cover structure. The top, bottom and sides of the mattress cover will be secured in conventional manner, as by seams l.

In the purchase of a mattress of the type herein described, it will be apparent that the merchant can readily carry a large number of spring units of different strengths and also a substantial number of the elastic pads of varying resiliency, so that the customers knowing the weights of the occupants can readily select suitable spring and pad elements to form a combination which will assure them of the maximum comfort.

With the structure herein illustrated, it will be apparent that all of the padding used in the mattress is most effectively disposed for the comfort of the occupants, and that no reversal of the mattress will at any time be necessary, a1- though rearrangement of the component parts can be made as often as desired and to suit dilerent conditions.

Various modifications in the precise arrangement and construction of the various elements will readily suggest themselves to those skilled in the art, but Within the scope of the present invention as claimed.

Having thus described the invention, I claim:

1. A mattress comprising a rectangular cover having a padded top, a bottom and peripheral walls, three sides of the wall divided intermediate the top and bottom and provided with interlocking means for removably securing said parts, a plurality of springs arranged within the cover in two groups on opposite sides of the medial line extending from head to foot, each group of springs being secured together as a unit, the springs of a group being of uniform resiliency and the springs of the respective groups being of a different resiliency, two pads of resilient material each coextensive in area with one group of springs mounted thereon and independent thereof, said groups of springs and said pads being interchangeable within the cover whereby the resiliency of the mattress on either side of the medial line extending from head to foot may be varied as desired.

2. A mattress comprising a rectangular cover having top, bottom and peripheral walls, three sides of the wall divided intermediate the top and bottom and the parts connected by a slide fastener of the zipper type, two groups of coil springs, the springs of each group secured together, a supplementary cover for each group of springs, the springs of each group being of uniform resiliency and each of said groups with its cover arranged to cover half the area of the mattress on either side of a medial line extending from head to foot, two independent pads of resilient material each coextensive with one and two independent spring elements group of springs, said pads being of different resilience and positioned intermediate the covers of the grouped springs and the top of the mattress cover, said pads and grouped springs interchangeable as units to vary the resilience of the mattress as desired on either side of the medial head to foot axis thereof.

3. A mattress comprising a cover of the box type formed in two hingedly connected parts with means for releasably securing said parts and two independent spring elements each formed of a plurality of coil springs, the coil springs in one element being stiffer than those in the other, the said spring elements combined being coextensive with the cover and separated on a line extending from head to foot of the mattress.

4. A mattress comprising a cover of the box type formed in two hingedly connected parts with means for releasably securing said parts each formed of a plurality of coil springs, the coil springs in one element being stiffer than those in the other, the said spring elements combined being coextensive with the cover and separated on a line extending from head to foot of the mattress, with padding interposed between the upper surface of the spring elements and the top part of the cover.
