What is a memory foam mattress?

Memory foam mattresses are a popular choice due to the benefits they provide. Well recognised for providing remarkable support, comfort and pressure relief, memory foam mattresses soften and mould to the contours of the body.

What is memory foam and how does it work?

Memory foam is sometimes also referred to as viscoelastic polyurethane foam. It mainly consists of polyurethane with additional chemicals that enhance its viscosity and density.

The foam works to restore its original structure when it is deformed. Once pressure has been removed, memory foam returns to its natural state slowly. Over time, the foam will remember your body shape and mould to your sleeping position.

What are the benefits of a memory foam mattress?

Superior sleep experience

By moulding to the contours of your body, memory foam mattresses offer personalised and customised support. Your body heat softens the foam allowing it to support your body which is believed to promote superior sleep.

Pressure relief

Memory foam structure reacts to body temperature to mould around you as you sleep. Your body weight becomes evenly distributed which helps to relieve pressure points from heavier parts of your body.

Customised support

High-density foam provides good support, comfort and spinal alignment. By softening around the curves and natural lines of your body, memory foam remembers your sleeping position to give you optimised and customised support.

What is memory foam made of?

Traditional

Traditional memory foam mattresses are made from polymer polyurethane which is combined with other chemicals for enhanced viscosity and density.

Due to its high-density levels, traditional memory foam mattresses tend to retain body heat.

Gel

Also made from viscoelastic foam, gel mattresses are infused with gel beads during the production process.

The gel foam allows the mattress to return to its original shape at a faster pace and regulate temperature, so you remain cool in summer and warm in winter.

Open cell

Open-cell memory mattresses use the same materials as traditional memory foam mattresses but follow a different internal structure.

Internal pockets are placed in open cell mattresses allowing increased ventilation and airflow which helps distribute heat.

How long do memory foam mattresses last?

The average mattress is expected to last anywhere from five to eight years. If your mattress is over eight years old, is affecting your quality of sleep, is permanently damaged or has stains, it could be a sign that your mattress is reaching the end of its lifespan.

Are memory foam mattresses hot?

Typically, memory foam mattresses do retain heat due to the internal structure of the mattress. However, the viscoelastic materials can’t be penetrated by dust mites and improve spinal alignment and pressure relief resulting in increased blood circulation.

If you are a warm sleeper who is sensitive to heat, a cool memory foam mattress could be a great option for you. ComfiCel Cool preserves less heat in the summer while remaining cosy throughout the winter.
