Frequently Asked Question

Will I get hot on the mattress?

Wherever possible we use temperature regulating materials that prevent the build-up of heat. Mattress covers are intelligently ventilated to encourage airflow and ensure breathability. We also use gel-infused and open-cell foams that have cooling properties.


Can I use an adjustable mattress on a standard bed base?

Yes. Whilst our adjustable mattresses are specially designed to work with an adjustable bed, they are also perfectly compatible with a static bed base.


What are the different layers of the mattress?

1. Ventilated cool weave cover

Protects the mattress and helps regulate body temperature to prevent heat build-up.

2. Cool Gel-Infused Foam

Comfort surface foam infused with hi-tech cooling gel to combat body heat.

3. Memory/Visco Foam

Contours to your body shape for premium comfort keep you in the same rest position for longer.

4. Comfort Support Foam

High-density, firm foam that provides comfortable support and encourages proper posture.

5. Anti-slip Base Cover

Durable base cover that grips to the bed base, prevents mattress movement and ensures stability.
