The range of foam materials available for bedding and mattress production has increased in recent years. Particularly flexible polyurethane (PU) foams have a number of resilient properties.

One type of flexible PU foam is memory foam. Memory foam, also known as viscoelastic foam, was originally designed by NASA in the 1960s. Made from polyurethane, memory foam was specifically developed to counteract extreme pressures astronauts faced when exiting and entering the Earth’s atmosphere. This great focus on comfort under extreme pressures makes memory foam ideal for mattresses, pillows and mattress toppers.

Why choose memory foam?

Known for its superior support and comfort, memory foam has its own set of characteristics which makes it ideal for a range of bedding products and requirements.

Pressure and recovery time: Viscoelastic foam uses the body’s heat to soften and mould to the body shape. Memory foam is generally made of material with higher density than other resilient foams, and slower recovery time than standard foams. This feature can improve comfort and support for users, especially around pressure points.

Optimal shape for excellent comfort: Memory foam mattresses change shape with the body. They distribute weight evenly and reduce pressure on low lying points such as the shoulders, ensuring an optimal spinal alignment. This makes this type of memory foam mattress feel almost personal to you, also helping to relieve aches and pains, as well as improving blood circulation.

Durability: Memory foam mattresses are highly durable and add longevity to a mattress.

Memory foam applications for different markets

In a medical setting memory foam is ideal for situations where a patient must remain immobile for long periods of time, helping to reduce discomfort and issues caused by long term pressure and loss of blood to particular areas of the body. In this instance, memory foam offers a superior experience.

It is also used for improved comfort in seat cushions where a user will be stationary for long periods, such as those found in wheelchairs, reducing pain, discomfort, and possible irritation to the seated person. Memory foam can also be found in protective equipment such as helmets.
