It has long lbeen the custom in the upholstered furniture
business to utilize various forms of edge rolls on the
base section of upholstered units to position and retain
screw means 16a, connect each side rail 14 with the
cushioning thereon. Many of these prior edge rolls in
volved `considerable stitching operations in the assembly
thereof and, oftentimes, a complex combination of pat
tern making and stitching land/or stapling in connection
with other components forming the finished upholstered
back posts 15. In addition, leg plate members 18 onto
which legs 19 are conventionally secured are shown dis
posed beneath the frame of the base section 10.
Noting particularly the structure disclosed in FIG. 2,

and the rear rail 12, the engagement thereto «being through
the use of a conventional clamp member 21a (see also

From the preceding it should be apparent that the
applicants have provided a new and novel edge roll which
is readily assembled and which is effective during use.
The edge roll includes a foam or cellular type material laid

base section of an upholstered furniture unit, with the
entire structure being simplified to eliminate the thread

front rail, said rear rail, and said side rails, a rigid base
member mounted on and extending inwardly from the
outer edge of said rigid bearing surfaces partly towards

material disposed thereon and a decorative fabric secured
thereto, said decorative fabric overlying said foam mate
