Originally, engineers from the National Aeronautics and Space Administration (NASA) developed memory foam, or viscoelastic polyurethane foam, for astronauts in the 1960s. In the 1990s, manufacturers began to use memory foam in bedding.
According to the Polyurethane Foam Association (PFA), memory foam is a popular bedding option due to its body-conforming capabilities, comfort, and supportiveness.
The PFA also notes that memory foam may provide benefits for certain people. For example, people with reduced mobility may benefit from the foam’s ability to redistribute weight and surface pressure, which may help prevent bedsores.

How to use
Instead of buying a memory foam mattress, people can purchase a memory foam mattress topper. This is a layer of memory foam that individuals can secure to the top of their mattresses. Some are also available for just one-half of the bed, which may suit couples with different bedding preferences.
Memory foam mattress toppers can make the existing bed feel more comfortable and last longer. However, while memory foam mattress toppers can be an affordable alternative to a memory foam mattress, even the best ones will not last as long as a full memory foam mattress or provide all of the same benefits.
The potential health benefits associated with memory foam mattress toppers include:
- Motion isolation can allow a person to toss and turn without disturbing anyone else in the bed.
- The antimicrobial ability of memory foam can help repel dust mites, bacteria, and fungi.
- A memory foam mattress topper may benefit people with pressure ulcers. A 2017 study found that adding a memory foam layer to hospital mattresses reduced pressure injuries in patients with severe illness.
- A memory foam mattress topper may also suit people who feel the cold or sleep in cooler climates. Memory foam is able to
retain heat well.

Memory foam can release strong-smelling gases. A 2019 study found that memory foam can release gases called volatile organic compounds (VOCs), which can cause adverse health effects. However, the researchers did not investigate whether the levels of VOCs in memory foam harmed health.
Prospective purchasers can reduce their risk of exposure to toxic chemicals by opting for products made with eco-friendly materials. The CertiPUR-US program tests products to determine whether they meet standards for emissions and were made with or contain toxic chemicals.
It is also worth noting that memory foam is a flammable material and, therefore, a known potential fire risk. People should keep cigarettes, heaters, and any other potential ignition sources away from the mattress topper. Additional measures to take include making an escape plan in case of fire and installing smoke alarms.
