What size is a small double mattress?

Small double mattresses measure 4 feet wide (120cm) and 6 feet 3 inches long (190cm). Although they are 6 inches narrower than a traditional double mattress, they will fit two adults (if you don’t mind snuggling up a bit) and are ideal for bedrooms with limited floor space. They’re also a good choice for any individual who wants a bit more space to sprawl out in bed, or as a teenager’s first double mattress. These 4ft wide mattresses come in a variety of depths and comfort levels. We also offer regular double mattresses where required.

What is the best small double mattress?

At Sussex Beds, we are proud to offer a wide variety of small double mattresses as we understand that what works for one person doesn’t necessarily work for another. No matter what style or comfort level you’re looking for, our team is here to help you pick out the best small double mattress for you. Some of our popular small doubles include:

Small double memory foam mattresses – Made to remember the specific contours of your body, our small double memory foam mattresses will keep you warm and comfortable all night.

Small double pocket sprung mattress – Benefit from optimum spinal alignment with pocket springs individual sewn into their own pockets.

Small double firm mattress – If you need something a little firmer for additional support, we offer a wide range of firm small double mattresses for you to choose from.

Small double soft mattress – If you prefer to sink into your mattress as night, our small double soft mattresses are ideal for you.

Does a double fitted sheet fit a small double mattress?

While it’s not a problem to use a double fitted sheet on a small double mattress, you may find that due to the difference in dimensions, the double fitted sheet is slightly too big and may bunch up a bit. This is because double fitted sheets are designed to fit 4ft 6in wide mattresses whilst a small double mattress measures 4ft wide. We offer a variety of fitted sheets to fit all mattress sizes, including 4ft small double bed sheets.
