Unlike the feather filled pillows, memory foam does not lose its shape over time. There will never be a need to “fluff” this type because it is designed to, as stated before, resist motion transfer. They are made primarily from polyurethane, and material specially manufactured to keep its form for years to come, which also lends to the products longevity versus traditional ones that should be replaced roughly every 1 to 3 years.
