Hourglass, Continuous and Offset<br />
Coils.<br />
Coir pad: An insulator pad made<br />
from coconut husk fiber, garnetted,<br />
needled, bonded and pre-cut to<br />
size.<br />
Comfort system: Refers to the<br />
upholstery layers of the mattress,<br />
generally consisting of a combination<br />
of materials (cover, cushioning,<br />
topper pad, insulators, etc.).<br />
Conjugate polyester fiber: Spirally<br />
crimped fiber that is crimped chemically<br />
rather than thermally. Is very<br />
durable and resilient.<br />
Continuous coils: An innerspring<br />
configuration in which the rows of<br />
coils are formed from a single piece<br />
of wire.<br />
Conventional bedding products:<br />
Mattresses and foundations in the<br />
conventional adult sizes of twin,<br />
twin extra long, full, full extra long,<br />
queen and king.<br />
Convertible sofa: A sofa with a<br />
bed folded beneath the seating<br />
surface, generally consisting of a<br />
mattress resting on a metal mechanism.<br />
Also called “sleep sofa” or<br />
“sofa sleeper.”<br />
Convoluted foam: Better known as<br />
“egg-crate” foam that is specially<br />
cut to produce hills and valleys,<br />
giving gentle softness and more<br />
surface comfort. Foam surface<br />
treatment is available in multiple<br />
patterns.<br />
Cornell test: Devised by Cornell<br />
University School of Hotel/Motel<br />
Administration. Designed to test<br />
cosmetic performance of bedding<br />
sets, such as body impression or<br />
support firmness. Two round surfaces<br />
are pounded into the finished<br />
product 100,000 times and checked<br />
periodically for failure or changes.<br />
Corner guards: Molded plastic or<br />
metal, (sometimes upholstered) fittings<br />
secured to foundation corners<br />
to prevent material damage from<br />
the bed frame.<br />
Cotton felt: Produced by a garnett<br />
machine which combs cotton and<br />
other fiber binders into a continuous<br />
web or layer. Several such<br />
layers combined are called cotton<br />
“batt”. For compressed cotton felt,<br />
thick layers of garnetted cotton<br />
fiber are mechanically compressed<br />
to reduce body impressions.<br />
Cotton linters: The short fibers<br />
adhering to the seed after the long<br />
staple fiber has been removed in<br />
the ginning process. Used in making<br />
cotton felt.<br />
Cotton pickers: “Fall out” from ginning<br />
or garnetting. These shorter<br />
staple cotton fibers are blended<br />
with linters to produce cotton felt.<br />
Crown: A convex surface on a mattress.<br />
Mattresses with a half-inch<br />
crown are a half-inch thicker at the<br />
center than at the edges.<br />
Cushioning: Materials that lie<br />
above the insulator and below the<br />
fabric covering in an innerspring<br />
mattress. These materials are typically<br />
combinations of polyurethane<br />
foam, cotton felt, and/or mademade<br />
fibers.<br />
Damask: Woven ticking produced<br />
on a loom that has yarns running<br />
at 90-degree angles to each other,<br />
the warp and the weft. The damask<br />
design is woven into the fabric<br />
rather than printed on the surface.<br />
Density: A measure of weight per<br />
cubic volume, usually expressed<br />
in pounds per cubic foot. Often<br />
referred to when discussing foam.<br />
Double tempering: Heating of wire<br />
components, usually in an oven, after<br />
they have been given shape or<br />
form and have been electronically<br />
stress-relieved. Refers to tempering<br />
coils as well as border rods and<br />
helicals in a complete spring unit.<br />
Dual-purpose: A broad term used<br />
to include all sleep pieces, which<br />
can be converted to other uses,<br />
including: convertible sofas,<br />
high-risers, daybeds, futons, etc.<br />
See Convertible Sofa.<br />
Dust cover: A woven or non-woven<br />
fabric attached to the underside of<br />
a foundation to prevent the collection<br />
of dust inside. May also be<br />
known as “sheeting” or “cambric.”<br />
Edge guard: Generally an extra<br />
component added to the edge of a<br />
mattress and/or box spring to give<br />
support on the sides.<br />
Engineered edge support: A special<br />
design where the coils on the<br />
outer edge of an innerspring unit<br />
are actually positioned under the<br />
border rod. Most units have the<br />
coils recessed from the edge, which<br />
can contribute to a “roll out of bed”<br />
feeling.<br />
Euro-top mattress: A mattress featuring<br />
a raised, squared-off surface<br />
finishing treatment filled with soft<br />
comfort layers and attached to the<br />
mattress upholstery at the tapeedge.<br />
Fabric cover: Cloth or textile material<br />
woven, knitted or felted of<br />
any fiber or mixture of fibers. Often<br />
referred to as “ticking” or mattress<br />
fabric.<br />
Fales pad: Compressed cotton felt<br />
that is stitched together to better<br />
retain compression.<br />
Fiber pad: Usually refers to manmade<br />
or natural fibers (wool, silk,<br />
etc.) that are garnetted, needled,<br />
carded and/or bonded together.<br />
Often used in quilting panels for<br />
mattress tops.<br />
Filler cloth: Refers to a plain fabric<br />
used on the top of a foundation
