Double Mattresses

Which double mattress is best for me?

The best mattress for you depends on your sleep preferences, position, and budget. Here’s a quick guide to help you browse:

The best double mattresses for couples

A double pocket-sprung mattress is a popular choice for couples as the pocket springs are individually wrapped, reducing the feeling of your partner moving during the night. This means you can sleep peacefully without being disturbed by their tossing and turning. The pocket springs also cradle your pressure points, ensuring a great balance of comfort and support.

The best double mattress for back pain

If you suffer from back pain, a double memory foam mattress is a fantastic choice. It will gently mould to your body, supporting every curve and helping to keep your spine aligned, which relieve pressure points. For more tips, check out our guide on how to sleep with back pain.

The best double mattress for temperature regulation

If you tend to overheat or get too cold at night, a double ActiGel mattress could benefit you. The gel layer responds to your body heat, helping to regulate your temperature. Plus, the gel provides cushioned comfort, moulding to your shape while helping to keep your spine aligned.

The best value double mattresses without sacrificing comfort

If you're on a budget but still want a great night’s sleep, a double traditional sprung mattress offers excellent value for money. These mattresses are durable and available in various comfort grades, so no matter your sleeping position - whether you're a side sleeper or prefer lying on your back - you'll find a budget-friendly option without sacrificing quality.

The best hypoallergenic double mattresses

Breathable materials in these mattresses also help maintain airflow, essential for minimising allergy triggers.

What’s the best comfort grade for your sleeping position?

• Side sleepers: Soft double mattresses are usually best; they respond to pressure points and help keep your spine straight.
• Back and front sleepers: Firmer double mattresses provide the support needed to keep your body aligned naturally.
