which ranges between approximately 1.0 and approximately 4.0 cubic
foot. Moreover, it will be understood that polyurethane foam filled
article of furniture 12 may be one component of an article of
furniture which may comprise frameless and non-frameless
components.
[0037] Bag associating step 40 generally comprises the step of
associating polyurethane foam filled article of furniture 12 with a
bag 16 having an aperture 18. More particularly, bag associating
step 40 includes the step of placing polyurethane foam filled
article of furniture 12 inside bag 16, through aperture 18. Bag 16
may comprise any one of a number of sizes, shapes, and/or
materials--with the only limitation being that it must be capable
of retaining polyurethane foam filled article of furniture 12.
Examples of suitable materials for fabricating bag 16 include
conventional substantially airtight, flexible materials such as,
for example, a bag fabricated from plastic, natural and/or
synthetic materials, etcetera. Aperture 18 may comprise any one of
a number of sizes and shapes--its only limitation being that it
must be capable of allowing polyurethane foam filled article of
furniture 12 to pass therethrough.
[0038] Reducing step 50 generally comprises the step of reducing
initial volume 14A of polyurethane foam filled article of furniture
12 to a reduced volume 14B. As is shown in FIG. 1, initial volume
14A of polyurethane foam filled article of furniture 12 is shown in
step 50A, prior to reducing step 50, and reduced volume 14B of
polyurethane foam filled article of furniture 12 is shown in step
50B, subsequent to reducing step 50.
[0039] Reducing step 50 may include providing a vacuum source 52
which is capable of decreasing air pressure within a confined area,
such as, for example, bag 16. Vacuum source 52 may then be
associated with aperture 18 of bag 16 such that a substantially
airtight seal is formed between vacuum source 52 and bag 16 via a
sealing member 19. For purposes of the present disclosure, vacuum
source 52 may comprise a centrifugal blower manufactured by Paxton
Products of Camarello, California. Sealing member 19 may comprise
any one of a number of sealers including, but not limited to, a
drawsting, clamp, ring, elastic band, tie, clip, or any other
sealing structure known to those having ordinary skill in the art
with the present disclosure before them. Next, vacuum source 52 may
decrease air pressure within bag 16 and, in turn, within
polyurethane foam filled article of furniture 12 to the extent that
the air pressure within bag 16 and polyurethane foam filled article
of furniture 12 is less than atmospheric pressure. As such, bag 16
and polyurethane foam filled article of furniture 12 are reduced
from initial volume 14A to reduced volume 14B.
[0040] Reduced volume 14B of polyurethane foam filled article of
furniture 12 may be approximately two-thirds of initial volume 14A
or less. Preferably, reduced volume 14B of polyurethane foam filled
article of furniture 12 is approximately one-half of initial volume
14A or less, and more preferably, reduced volume 14B of
polyurethane foam filled article of furniture 12 is approximately
one-third of initial volume 14A or less.
[0041] Reducing step 50 may also comprise the step of sealing bag
16 to substantially preserve reduced volume 14B of polyurethane
foam filled article of furniture 12 via sealing member 19 or any
other means for preserving reduced volume 14B known to those having
ordinary skill in the art with the present disclosure before them.
It will be understood that "substantially preserving reduced volume
14B" will generally mean that reduced volume 14B may not increase
to equal initial volume 14A until such preserving means which are
employed are deployed from bag 16 and polyurethane foam filled
article of furniture 12.
[0042] Package associating step 60 generally comprises associating
polyurethane foam filled article of furniture 12 with a package 20.
Package 20 may comprise a size which is substantially smaller than
conventional packages for polyurethane foam filled articles of

filled article of furniture 12 results in a substantial reduction
in size of polyurethane foam filled article of furniture 12. As
such, package 20 may comprise a volume less than initial volume 14A
of polyurethane foam filled article of furniture 12, yet must
comprise a volume at least slightly greater than reduced volume 14B
of polyurethane foam filled article of furniture 12. Preferably,
package 20 may comprise a volume only slightly greater than
two-thirds of initial volume 14A of polyurethane foam filled
article of furniture 12, and more preferably, package 20 may
comprise a volume only slightly greater than one-third of initial
volume 14A of polyurethane foam filled article of furniture 12.
