`.T'heibottomi 8" is‘ of'eduivalent.construction. 'That
`is‘t‘o' say, it‘is a‘ rectangular panel or sheet or
`transparent commercial plastic having the de
`sired semi-rigid but appropriately pliant char
`acteristics. The interconnecting boxing means is
`denoted by the numeral iii and this has its mar
`ginal edge portions stitched or otherwise con
`nected to the coacting marginal edge portions of
`the top and bottom panels whereby the several
`components contribute in forming the customary
`box-like casing for the insertable and removable
`conventional mattress I2. The boxing embodies
`transverse reaches or walls 14 and H5 and longi
`tudinal side walls Hi and 20. The stated boxing
`Ill is, more speci?cally, a strip of rough-textured
`elasticized, cotton webbing, which will hold the
`mattress cover ?rmly to the mattress. It will be
`noticed in this connection that the marginal edge
`portions of the elasticized webbing, that is the
`upper and lower edges 22 and 24 (see Figures 3
`and 4 in particular), overlap the marginal edges
`of the plastic panels and are stitched or other
`wise secured thereto as at 26. These overlapping
`portions provide ?anges which are some two
`inches in width and which not only strengthen
`the over-all construction but actually constitute
`anti-slipping members to assist in preventing a
`sheet or other article of bed clothing (not shown)
`
`"i'l’he'improved'cover fomiing‘ the subjectsmatter

`bination of commercial plastics and special fabric.
`More speci?cally the cover, in its preferred em
`bodiment, is characterized by top and bottom
`plastic panels which are normally ?at and sub- '
`stantially shape sustaining in nature and yet _
`pliant enough to conform to and fit over coacting
`mattress surfaces with requisite nicety. These
`two panels have their marginal edge portions in"
`terconnected 'by boxing means the principal prop
`erties of which are elasticity, porosity for ven
`tilation, and rough surface ?nish to offset undue
`slipping and sliding of bed clothing.
`In carrying out the principles of the invention
`in accordance with the above, a form-?tting self
`adjusting mattress cover is had which reduces
`wrinkling to a minimum, eliminates shifting and
`displacement in relation to the encased mattress
`and assists in sustaining the usual sheet neatly
`and securely in position.
`‘
`Other objects, features and advantages will be
`come more readily apparent from the following
`description and the accompanying sheet of illus
`trative drawings.

`from slipping off of the mattress cover once it is
`properly positioned by hand. Obviously the elas
`tic retentive properties of the webbing serve to
`draw the plastic panels together. and to bind them
`in ?rm contact with the coacting surfaces of the
`mattress. The over-all cover is therefore yield
`ingly conformable and satisfactorily held in place.
`In addition the rough and elastic surfaces pro
`vide the aforementioned anti-slipping results. In
`actual practice the webbing will‘ be possessed of
`the “two-way stretch” as shown in the drawings.
`The weaving is such that desired ventilating prop
`erties are also had. The front end of the webbing
`is provided with a slot whose ends extend‘ around
`the adjacent corner portions and said slot is pref
`erably closed with a Zipper fasteners 28. This
`provides an openable and closable ‘mouth to ‘fa
`cilitate application and removal of the cover. _,
`The longitudinal sides 20 are also provided with
`forward and rearward slits to permit access to be
`‘had to the usual mattress handles or grips as
`shown at 3| in Figure 2. By preference these slits
`will be provided with suitable closure means. In
`Figures 1 to 4 inclusive the closure means takes
`the form of so-called Zippers 30. In the modi?- -
`cation shown in Figure 5 the slots will have mar
`ginal stitched-on-tapes 34 which may be over
`lapped and secured together by snap fasteners,
`buttons or the like 36.
`It may be pointed out that the slits or openings
`for mattress handles would be necessary only on
`covers used on large mattresses of the full, half
`and three-quarter sizes which are usually pro
`vided, as is known to facilitate handling and
`turning; Neither closure means or snap fas
`teners would be necessary on small lightweight
`pads and so-called mattresses for cribs, baby
`carriages, bassinets and so on. _
`The gist of the invention resides in a novel
`slip cover for mattresses, cushions and the like
`characterized by'transparent ?at top and bot
`tom panels of requisite ?rmness and conform
`ability adjustably joined around the marginal
`edges with elastic boxing means as herein both
`broadly and speci?cally comprehended.
`A careful consideration of the foregoing de
`scription in conjunction with the invention as il
`lustrated in the drawings will enable the reader
`to obtain a clear understanding and impression

`of the alleged features of merit and novelty suf
`flcient to clarify the construction of the inven
`tion as hereinafter claimed.
`.
`Minor changes in shape. size, materials and
`rearrangement of parts may be resorted to in
`actual practice so long as no departure is made
`from the invention as claimed.
`Having described the invention, what
`claimed as new, is:
`,
`V
`.
`_.
`In combination, a compressibly resilient mat
`tress of a given size, a substantially flat top
`panel, a. corresponding ?at bottom panel under
`lying said top panel and disposed in normally
`spaced parallelism with said top panel, said
`" panels being each rectangular in shape and of
`a size conformable in size with that of the top
`and bottom sides of said mattress, said panels
`being of transparent smooth surfaced moisture
`proof pliant sheet material, and a relatively rec
`tangular boxing at right angles to said panels
`and having upper and lower marginal edge por
`tions corresponding with the cooperating mare
`ginal edge portions of said top and bottom panels
`and combining therewith and de?ning a box—
`like casing enveloping said mattress, said bOXs
`ing being made of material which is rough ?I1~
`ished woven elastic webbing and completely
`bordering the marginal edges of said panels, said
`webbing being sufiiciently stiff in texture and yet
`yieldable to a degree that when said panels are
`moved in directions away from each other the
`webbing is placed under tension, and the upper
`and lower marginal edge portions of said box
`ing overlapping the cooperating and correspond
`ing marginal edge portions of said top and bot
`tom panels and being stitched thereto and rein
`forcing the over-all casing and also providing
`anti-slipping ?anges which, in use, serve to as
`sist in retaining bed clothing satisfactorily in
`place on the uppermost panel.
