What size is a small double mattress?

A small double mattress is 4ft wide and 6ft3 long – the standard length for most mattresses. The width is bigger than a single mattress, which makes it ideal for individuals who like to spread out, or couples who like a snug fit. They’re also perfect for growing kids, as it allows them a more comfortable sleep.

Can a small double mattress accommodate two people?

Yes, a small double mattress can accommodate two people, but it’s important to keep some things in mind. As it’s smaller than a double mattress, the fit for two people is more snug. For those who like to toss and turn, it may be better to opt for a larger mattress. However, a small double mattress is a great option for compact rooms.

How thick should a small double mattress be?

A good quality small double mattress should be between 8-12 inches. However, some small double mattresses will be thicker due to extra layers, like hybrids with memory foam or latex tops. These additional features could be beneficial for adults who need more support as they sleep, or growing teens. It’s important to keep this in mind when opting for the right mattress, as small rooms could be made to look smaller due to the added height. To counteract this, you may want to compensate with a lower bed frame. We stock a range of styles to choose from!

Can a full fitted sheet fit a small double mattress?

A full fitted sheet, also known as a double bedsheet, is too big for a small double mattress. Bed sheets need to be tight to the mattress to avoid bunching and causing discomfort as you sleep, so it’s best to opt for the right small double size.

Will a double mattress fit a small double bed?

No, a double mattress will not fit a small double bed. Though the length of both a small double and double bed measures 6 ft 3 in, the width of each differs. A small double bed frame is 4ft wide, whereas a double bed is 4ft 6 in wide. This means that a double mattress will hang over a small double bed frame. Not only is this unsafe, but you will also not get the best support due to the uneven surface. It’s best to opt for a small double mattress for a small double bed frame. We highly recommend that you always buy the right fitting mattress for your chosen bed.

What types of small double mattresses can I choose from?

Pocket sprung

Pocket sprung mattresses feature individually encased springs that move independently and adapt to your body as you toss and turn during the night. This design minimises motion transfer, making it a great option for couples who want uninterrupted rest.

Memory foam

For a mattress that moulds perfectly to your body, memory foam is a go-to choice for many homes. It absorbs weight and cushions pressure points to reduce discomfort caused by hard or soft sleeping surfaces.

Natural fillings

Crafted with breathable layers of wool and cotton, natural filling mattresses offer comfort with a touch of luxury. They’re also a great pick if you’re looking for a hypoallergenic small double mattress.

Combined or hybrid mattresses

Hybrid mattresses blend traditional spring support with comforting layers of memory foam, latex, or cooling gel. Both layers together offer both support and contouring comfort which is ideal for couples who want the best of both worlds.

Open coil or traditional springs

The most traditional option, an open coil mattress are made up of interconnected coils to deliver a dependable, full-surface support at an affordable price. Expect that classic firm, springy and bouncy feel that many know and love.

Gel mattresses

Gel mattresses are designed to regulate temperature, making them perfect for hot sleepers seeking a cooler, more breathable night's rest.

Latex mattresses

Latex mattresses are naturally hypoallergenic and temperature-regulating, making them perfect for those who sleep hot. They offer a responsive, supportive feel that combines durability and breathability.

What firmness level should I choose for a small double mattress

• Soft mattresses: A soft small double mattress could be ideal for you , depending on your weight and height. The extra space also means it’s perfect for a guest room. In terms of comfort, it’ll be sure to provide you with that sink-in feeling and is a great match for side sleepers, especially if you have a lighter build. You could also support your slower back better if you’re a side sleeper by investing in a body pillow to reduce lower back pain.
• Medium mattresses: For both back support and cloud-like comfort, a medium small double mattress is just what you need for a good night's sleep.
• Firm mattresses: Firm small double mattresses provide the support for those with back pain by aligning your spine for a restful sleep. Along with the firm tension, small double beds are slightly wider than single mattresses, which makes them a great choice for people with larger statures.
• Extra firm mattresses: For even further support, or large statures, an extra firm small double mattress will provide the best joint support for pressure points and the best spinal alignment.
