The flat platform under an upholstered chair's seat cushion, usually covered in plain fabric. The deck should be firmly resilient, and you should not be able to feel the springs.
The extra layer applied to certain fabrics, such as chenille, for upholstery applications. Without backing, they will stretch and sag. Look for fabrics marked "upholstery weight" or "all-purpose."
A tightly woven fancy trim that resembles a braided ribbon. On upholstered furniture, gimp is most commonly used to conceal tacks where fabric meets an exposed wood frame.
The layout of fabric pieces so that pattern flows unbroken across seams and cushions. Done well, seams will be nearly invisible. Large-scale patterns may require substantially more yardage.
Cutting fabric on the cross grain, usually to avoid seams in large upholstered pieces. Fabric is also referred to as railroaded when the pattern runs horizontally off the bolt. Fabric with directional patters or pile (such as velvet) should not be railroaded.
One complete cycle of a pattern in a fabric or wallpaper. A textile with a large repeat will require substantially more yardage to upholster a piece than a solid fabric, particularly when applied to a sofa.
Tightly woven edges that prevent fabric from fraying on the roll. The selvage must be cut away for many fabrics to drape smoothly.
Having no loose or semiattached back cushions. This style of upholstery looks tailored but can be less comfortable for lounging and is harder to clean than loose cushions.
The threads that run vertically in a length of fabric. Looms are strung with warp threads that are interwoven with weft threads.
The set of yarns running horizontally to and interlaced with the warp to produce a woven fabric. Also called filling.
