Gel Mattresses

What is a gel mattress?

A gel mattress features cooling gel elements that help manage heat and improve comfort. The gel is usually infused into memory foam mattresses or added as a layer near the top. This helps reduce the heat retention that standard memory foam is known for, while still providing the contouring and pressure relief. Some models combine gel foam with pocket spring mattresses or latex mattresses, creating a hybrid mattress that offers temperature control alongside responsive support.

What are the benefits of a gel mattress?

Temperature regulation

Gel mattresses help manage body temperature by absorbing and dispersing heat. The gel layer pulls heat away from your body, keeping you cooler than with standard memory foam. Useful if you tend to overheat at night or sleep hot. For more advice on staying comfortable, read our guide on how to stay cool at night.

Pressure point support

The gel layer moulds to your body shape, cushioning pressure points such as your shoulders, hips and lower back. This works similarly to memory foam but without the heat build-up. The base support layers keep your spine aligned while the gel provides surface comfort.

Motion isolation

Gel foam absorbs movement, so you're less likely to feel your partner shifting position during the night. Helpful if one of you is a restless sleeper or tends to get up frequently.

Durability

High-quality gel mattresses maintain their shape and support over time. The gel layer doesn't break down as quickly as some foams, so the mattress stays comfortable for longer.

Versatile firmness options

Gel mattresses come in different firmness levels and can be combined with springs or other materials. This makes them suitable for various sleeping positions and support needs.

What firmness levels are available?

• Medium gel mattresses: Softer feel that cushions pressure points. Best for side sleepers who need extra padding around hips and shoulders.
• Firm gel mattresses: Provide more support with less sink. Suitable for back sleepers who need to keep their spine aligned and prevent the lower back from dipping.
• Very firm gel mattresses: The firmest option, which keeps hips lifted and spine straight. Works well for stomach sleepers or anyone who prefers a harder sleeping surface.

Are gel mattresses good for hot sleepers?

Yes. Gel mattresses were specifically designed to address heat retention in memory foam. If you overheat at night, wake up sweaty, or find standard memory foam too warm, a gel mattress should sleep cooler. The gel layer actively manages temperature rather than just trapping body heat.

For additional cooling, pair your gel mattress with cool pillows and summer bedding. If night sweats are a regular problem, read our article on what causes night sweats and how to stop them.

Yes. All our mattresses include our 100-Night Comfort Guarantee. This gives you up to 100 nights to make sure the gel mattress works for you. If not, you can exchange it for another one.
