Small double bedroom? It’ll feel more spacious with furniture that fits, like a small double mattress and bed. Exactly halfway in size between a single and a double mattress, small double mattresses give you the best of both worlds. Shop our extensive range of mattresses including memory foam, pocket spring, hybrid and more.

Choosing the right small double mattress

Even with so many options to choose from, identifying the small double mattress that's right for you and your home doesn’t have to be a difficult task. Just ask yourself a few quick questions:

Small double mattresses in a range of fillings

Small double mattresses may not be so commonplace as double mattresses for example, but that doesn’t mean your choice will be limited. Our range includes mattresses of all types - pocket spring, memory foam and hybrid as well as luxurious mattresses with natural fillings and pillow tops.

A soft or a firm small double mattress for your comfort

Our mattress collection covers the full range of comfort levels from soft to extra firm. What you choose depends on personal preference, although your body type and sleeping style can make a difference. Our mattress buying guide goes into more detail. If your mattress will be used in a guest room and slept on by different people, then opt for a medium-feel small double mattress.

Small double mattresses brands for a high-quality sleep

If you’ve had success with a mattress from a particular brand, then that’s a great place to start. We’re proud to stock brands, such as Harrison Spinks, Vispring and Sleepeezee. Browse our collection of small double mattresses to find your favourite brand or a mattress that offers specific benefits - like hypoallergenic materials, cooling layers or a focus on sustainability.

What else does your small double mattress need?

A small double mattress should facilitate good sleeping posture and spinal alignment - and the right pillow can help enormously too. Browse our bedding and pillows department for new pillows and, while you’re there, take a look at our mattress protectors. Turn your small double bedroom into a cosy and relaxing bedroom with space-efficient bedroom storage furniture like an ottoman divan base, bedside tables and a wardrobe with sliding doors
