Sprigle et al. proposed the following criteria for defining and describing cushion characteristics: [6] Material and construction. Cushions using cellular materials – foam (convoluted, segmented), flexible matrix, viscoelastic foam or matrix, nondeforming foam or matrix; Cushions containing fluid – viscoelastic fluid, air cushion, water cushion
It is a solvent for adhesives in aerosol glues that glue foam cushions together. [6] It is a solvent in asphalt production, in the aviation industry for maintenance, and in synthetic fiber production.

Most standard memory foam has a density of 16–80 kg/m 3 (1 to 5 lb/ft 3). Most bedding, such as topper pads and comfort layers in mattresses, has a density of 48–72 kg/m 3 (3 to 4.5 lb/ft 3). High densities such as 85 kg/m 3 (5.3 lb/ft 3) are used infrequently. The firmness property (hard to soft) of memory foam is used in determining comfort.
