Memory Foam Mattresses

What is a memory foam mattress?

Memory foam mattresses are constructed from polyurethane foam, first invented by NASA scientists in the 1960s.

They can be made from pure memory foam, like TEMPUR mattresses, or combined with pocket springs to create hybrid memory foam mattresses.

How does memory foam work?

A memory foam mattress uses your body heat to mould and conform to your exact body shape as you sleep. This means that you experience comfort and support that is completely tailored to your body shape and weight.

The memory foam layer of your mattress is also incredibly responsive, meaning it pushes back against your body weight, helping to relieve the pressure that builds up in your joints over the day and soothes aches and pains.

How can a memory foam mattress help to improve your sleep?

Memory foam mattresses are specifically designed to enhance sleep quality and duration.

A memory foam mattress may be able to improve your sleep if you experience:

1. Disturbed sleep due to movement from you or your partner - Memory foam mattresses absorb movement, minimising disturbance from you or your partner shifting during the night.
2. Rolling into the centre of your mattress with your partner - Memory foam mattresses feature a 'no-roll together' design as the memory foam moulds around your body, preventing you and your partner from sinking towards the middle.
3. Discomfort from joint pressure - Memory foam mattresses are very responsive, which means that the memory foam layer actively pushes back against your body weight. It also evenly distributes your weight across the mattress to relieve pressure from your joints. This prevents unnecessary pressure from being placed on your back, hips, shoulders and joints.
4. Lack of support for your sleeping position - Whether you sleep on your side, back, front, or switch between them, a memory foam mattress adapts to your movements, providing consistent support throughout the night.
5. Feeling too cold during the night - Memory foam mattresses retain a small amount of your body heat, helping you to stay warm.
6. Disturbed sleep due to allergies - All memory foam mattresses are hypoallergenic. The visco-elastic foam structure cannot be penetrated by dust mites, hair, pollen or other allergens that can trigger allergy symptoms, such as sneezing.

Is a memory foam mattress good for back pain?

Yes, a memory foam mattress, especially an orthopaedic memory foam mattress, can effectively alleviate back pain.

An orthopaedic memory foam mattress is specifically designed to provide enhanced support for shoulders, back, and hips, promoting healthier sleep posture by aligning the spine and neck. This correct alignment distributes your body weight evenly across the mattress, reducing pressure on your neck, shoulders, lower back, and hips.

In addition to the enhanced orthopaedic support, you'll also benefit from the pressure relief properties of memory foam, making it a great option to consider if you suffer from back pain.
