Pocketed coil: See Marshall.
Polyurethane foam: See Urethane
Foam.
Print: A ticking fabric, which can be
a woven or non-woven sheeting,
commonly of synthetic fiber composition,
on which a design has been
printed.
Quilting: The surface treatment in
which the cover, foam and/or other
fibers are sewn together, using
various stitch patterns on quilting
machinery, including scroll or
panel quilters (single needle) and
multi-needle quilters.
Resilience: Surface liveliness and
spring-back ability.
Rollator test: An approximately
230 lb., six-sided roller is passed
across a sleep set to determine the
structural strengths or weaknesses
of the set and components (i.e.,
foam or quilt failure, breaking of
helicals and coils). The industry
standard to duplicate the life of a
mattress is 100,000 passes.
Rollaway bed/cot: A portable metal
bed/cot with a frame that folds
in half with the mattress when not
in use so it can be rolled away into
a closet (or elsewhere) for compact
storage.
Sheeting: a woven or non-woven
fabric other than knits that have a
degree of sizing and are somewhat
stiff.
Side rail: A metal or wood rail,
which hooks into the outside edges
of a headboard and footboard
to provide the support base for a
foundation and mattress.
Sisal: A product of the henequen
plant formed into a pad and used
as an insulator. Named after the.
small port of Sisal in Yucatan.
Slats: Narrow strips of wood used
to support the coils in the box
spring frame. Also used in a bedstead
to support the box spring.
Sleep Products Safety Council
hangtag: Used voluntarily by
bedding producers since 1987, the
safety hangtag program provides
critical consumer information about
the safe use of sleep products.
Manufacturers certify that they use
the tag only on mattresses that
meet the Federal Standard for the
Flammability of Mattresses and
Mattress Pads.The tag is available
in a hangtag or permanent label.
Smooth top: A plain surfaced
mattress, neither tufted nor quilted.
Also called button-free.
Spring wire: Wire made from high
carbon steel, characterized by
toughness, strength and ductility.
Typically furnished in 8 to 18 gauge
for bedding industry applications.
Steel unit construction (for box
springs): The spring construction
used as the main support system
inside a box spring.
Stitch bonded pad: See Fales Pad.
Straightline deflection: Pertains to
mattress innerspring construction
and refers to the constant ratio
between stress and strain, weight
and movement. The benefit is
that constant support is provided
regardless of the weight applied.
No bottoming out of soft spots.
Basically it means that two people
of unequal weight, sleeping on the
same mattress, receive the same
support.
Stretch knit: A heavy-weight mattress
ticking consisting of a top layer,
bottom layer and filling material
knitted together and intermittently
stitched to keep the filling yarns
stable.
Super zoned box spring frame: A
support, generally wood, attached
longitudinally to the underside of
a foundation for added support
where the main body weight rests.
Another important structural point
is that the vertical slats are turned
on edge for added strength. This
is extremely important on queen
sizes and for 4-poster beds where
typically no center support is
provided. Also known as a “center
rail.”
Tape: Fabric material that closes
over the rough-sewn edge where
the top and bottom panels are
joined to the border of a mattress
or box spring.
Tape edge: A specified type of
sewing machine designed to stitch
binding tape around the top and
bottom edges of the mattress,
joining the panels with the border
and closing the mattress.
Tempering: Heat treatment of
wire to reduce brittleness. Accomplished
by electric charge,
oven heat or both. Also known as
“stress relieved”.
Ticking: Fabrics for covering mattresses
and foundations. Common
