`world. spanning all races and classes of people. and are
`responsible for numerous maladies which affect people on a
`daily basis. Thus. problems encountered during sleeping
`commonly result in muscle aches. headaches. stiff necks.
`congestion. respiratory ailments. and a variety of other
`symptoms. Not only do sleeping disorders manifest them
`selves physically. they are frequently responsible for mental
`di?iculties as well. such as stress. tension. tiredness.
`irritability. mood changes. etc. While the problems attributed
`to sleeping dil?culties have been well known for a long time.
`e?orts to ?nd an eifective solution have been futile.
`O?entirnes. a major portion of sleeping dif?culties can be
`attributed to the use of a pillow. When a person lies or sleeps
`on a bed. the pillow keeps the person’s head elevated above
`the top of the matress. The amount of elevation a person
`needs will depend upon the orientation in which the person
`sleeps. and thus all people do not require the same amount
`of elevation. For example. when a person sleeps on his or her
`stomach. the natural position of the head is close to the
`mattress. and thus this person will need a pillow providing
`only a small amount of head elevation. When a person sleeps
`on his or her back. the natural position of the head is farther
`from the mattress. and thus this person will need a pillow
`providing a greater degree of elevation to support his or her
`head in proper alignment with his or her torso. For persons
`sleeping on their sides. the natural position of the head is still
`farther from the mattress. and thus such persons will need
`pillows which provide an even greater amount of elevation
`so as to support their heads in the proper position. Thus. the
`degree of elevation provided by the pillow will have a
`signi?cant impact on the person’s comfort level-either too
`little or too much elevation will cause a person’s head to be
`supported in an awkward position with respect to his or her
`torso. resulting in one or more of the aforementioned mala
`dies.
`One method for addressing this problem has been to
`manufacture a series of pillows having the same height. but
`with different degrees of ?rmness. Pillows having a low
`degree of ?rmness will readily compress. thereby supporting
`a person’s head at a low elevation with respect to his or her
`torso. Such pillows are intended for use by stomach sleepers.
`Firm pillows. on the other hand. will better retain their
`shape. thereby supporting a person’s head at a higher
`elevation with respect to his or her torso. Such pillows are
`intended to be used by side sleepers. Between these
`extremes. pillows having intermediate degrees of ?rmness
`may be fabricated to provide appropriate levels of support.
`and would be used. for example. by back sleepers.
`A long-standing technique for forming pillows having
`di?’erent degrees of ?rmness has been to vary the amount of
`stu?ing material used to ?ll the pillows. That is. using lesser
`amounts of stuffing material results in pillows which are soft
`and readily compressible. These pillows will progressively
`become both thicker and more ?rm as the amount of material
`
`SUMMARY OF THE INVENTION
`The present invention addresses these needs.
`One aspect of the present invention provides methods for
`making a series of pillows. each one of the pillows having
`a different height than the other ones of the pillows. In
`accordance with one method. a series of casings is provided.
`each casing including a gusset and a pair of panels connected
`to opposite sides of the gusset to de?ne a cavity. Each one
`of the gussets has a selected width. the width of the gusset
`in each one of the casings being dilferent than the width of
`the gusset in the remainder of the casings. Gussets having a
`width between about 0.50 inches and about 3 inches are
`preferred. Regardless of the width of the gusset. however.
`each of the casings preferably has about the same length
`girth and width girth. When each one of the casings is ?lled
`with about equal weights of a ?ll material. the pair of panels
`in the casings with relatively narrow gussets will bulge away
`from one another by greater amounts than the pair of panels
`in the casings with relatively wide gussets.
`In another method according to this aspect of the
`invention. a series of casings is provided. one of the casings
`including a pair of opposed panels directly connected
`together along spaced joining lines to de?ne a cavity. and the
`other ones of the casings each including a gusset and a pair
`of panels connected to opposite sides of the gusset to de?ne
`a cavity. Each one of the gussets has a selected width. the
`width of the gusset in each one of the casings being different
`than the width of the gusset in the other ones of the casings.
`Gussets having a width between about 0.5 inches and about
`3 inches are preferred Again. the length girth and width
`girth of each of the casings is about equal regardless of the
`width of the gusset. When each one of the series of casings
`is ?lled with about equal weights of a ?ll material. the pair
`of panels in the casings with relatively narrow gussets will
`bulge away from one ano?ier by greater amounts than the
`pair of panels in the casings with relatively wide gussets. and
`the pair of panels in the one casing without a gusset will
`bulge away from one another by a greater amount than the
`pair of panels in the casings with gussets.
`Another aspect of the present invention provides a set of
`pillows in which each pillow in the set desirably has about
`the same length and width girth. but a different height than
`the other ones of the pillows in the set. A ?rst pillow has a
`casing including a gusset having a ?rst width and a pair of
`panels connected to opposite sides of the gusset. A prede
`termined weight of a ?ll material is ?lled in the casing. At
`least one other pillow having a casing is also ?lled with the
`predetermined weight of the ?ll material. The casing of this
`other pillow includes a gusset having a second width greater
`than the ?rst width and a pair of panels connected to
`opposite sides of the gusset. whereby the ?rst pillow has an
`overall height which is greater than the overall height of the
`other pillow.
