Memory foam is polyurethane with additional chemicals increasing its viscosity and density. It is often referred to as "visco-elastic" polyurethane foam, or low-resilience polyurethane foam (see LRPu). Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. A lower-density memory foam is pressure-sensitive and molds quickly to the shape of a body pressing against it, returning to its original shape once the pressure is removed. Faster speed of recovery of a foam to its original shape after a weight is removed is sometimes claimed as an advantage by memory-foam mattress producers, who may talk of "newer generation" foams with "faster recovery."

Famous quotes containing the words memory and/or foam:
“Raising children is a spur-of-the-moment, seat-of-the-pants sort of deal, as any parent knows, particularly after an adult child says that his most searing memory consists of an offhand comment in the car on the way to second grade that the parent cannot even dimly recall.”
—Anna Quindlen (b. 1952)
““To dine!” she shrieked in dragon-wrath.
“To swallow wines all foam and froth!
To simper at a table-cloth!”
Say, can thy noble spirit stoop
To join the gormandising troop
Who find solace in the soup?”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
