Pillows come in a simple variety of constructions, including gusseting, corded edging and quilting. Each one offers a slightly different benefit to its overall performance.
Gusseted construction on sleep products is where a sidewall, ranging from 1/2" to 4" is created by building a border along the side of a product. When filled, this gusset helps to maintain the high loft (puffy) appearance of the pillow.
A decorative piping used around the edges of bed pillows adds subtle interest to clean lined fabrics. Sometimes the piping is finished with additional rows of stitching to emphasize the look; this is mainly an aesthetic embellishment with no contribution to the performance of the sleep product.
Quilting is the construction of layers of fabric and filling held together by patterned stitching, creating a padding effect. This helps to provide an extra layer of comfort to your bedding. This construction is frequently used in feather products to help contain the feathers and cushion sleepers from the hard quills inside.
