Double Mattresses

What are the dimensions of a double mattress?

Measuring 4 feet and 6 inches (135cm) in width and 6 feet and 3 inches (190cm) in length, a double mattress provides ample space for couples or single sleepers and is designed to sit securely on a double bed. For more information on sizing, read our bed and mattress size guide.

What firmness levels are available for double mattresses?

We offer a range of different firmness grades so you can find the right mattress for your sleeping position. These include:

• Soft double mattresses: Ideal for side sleepers, they allow the hips and shoulders to sink in, helping to relieve pressure points.
• Medium double mattresses: Suitable for back, side, and stomach sleepers or those that move around, they provide a balance of support and comfort.
• Firm double mattresses: Best for back or stomach sleepers, they offer additional support and a firmer surface to keep your spine aligned.
• Very firm double mattresses: Provide maximum support, great for those who sleep on their back.

The best double mattress for back pain

Each double mattress has its own features and benefits. For the 23% of UK poor sleepers who can't get comfortable in bed, finding the right one matters more. Here's what each offers:

• Pocket spring mattresses: This double mattress is best for couples or those easily disturbed by movement. Its individually wrapped springs provide support and minimise motion.
• Traditional spring mattresses: Best for those on a budget or who prefer a firmer feel.
• Memory foam mattresses: Best for side sleepers or those who prefer more cushioning, memory foam moulds to your body shape, providing pressure-relieving comfort.
• Combination mattresses: These double mattresses combine spring with foam, offering the best support and comfort.
• Gel mattresses: Ideal for those who get hot at night due to their cooling properties.
• Latex mattresses: Naturally cooling, breathable and hypoallergic, these are great for those who struggle with temperature regulation.
• Natural mattresses: Made with organic materials, these double mattresses are eco-friendly and well suited to those with allergies.
• Zip and link mattresses: Great for couples with different firmness preferences, they allow you to attach two different single mattresses together to make a double mattress.
