A single mattress is 90 x 190cm (3ft x 6ft 3in), the go-to size for kids’ rooms, guest rooms and smaller adult bedrooms. Choose a slimmer mattress for bunk beds and children’s beds, or a deeper one with extra comfort layers for grown-up sleepers. Memory foam, pocket sprung, hybrid and orthopaedic options are all here.

What Size is a Single Mattress?

A single mattress measures 90cm wide by 190cm long (3' x 6'3"), making it the most compact standard adult mattress size available in the UK. This size is ideal for smaller bedrooms, guest rooms, or children's spaces where maximising floor space is essential.

If you need guidance on choosing the right mattress size for your room, our mattress size guide provides detailed measurements and practical advice for all standard UK mattress dimensions.

How Deep Is a Single Mattress?

Depth varies depending on the type of single mattress you choose but typically range from around 15cm up to 30cm. Thinner mattresses, roughly 15 to 18cm deep, suit children's beds and bunk beds, where a lower profile is safer and easier to climb into. Deeper mattresses offer extra cushioning layers, ideal for adult single beds.

Types of Single Mattresses

We stock single mattresses in every filling type to suit different sleeping positions and needs:

• Single Memory Foam Mattresses: These soft foam mattresses contour to your body for pressure relief and comfort. They are perfect for side sleepers.
• Single Pocket Sprung Mattresses: These mattresses have individually wrapped springs that provide targeted support and minimise motion transfer.
• Single Open Coil Mattresses: Also known as traditional mattresses, these offer firm and reliable support at a lower price point.
• Single Hybrid Mattresses: Made with a combination of foam and spring for the best of both support and comfort.
• Single Latex Mattresses: These offer a similar feel to foam but provide a cooler sleep experience while being natural and hypoallergenic.
• Single Gel Mattresses: These provide responsive support and enhanced comfort similar to memory foam.
• Single Orthopaedic Mattresses: Mattresses that are engineered to support the spine and joints for those who experience back pain.

Single Mattress Firmness Options

You should choose a single mattress that suits your sleeping style and support needs:

• Soft Mattresses: Gives a cushioned and plush feel, but are less supportive for those with back issues. These single mattresses are best for side sleepers as they allow your body to sink in and relieve pressure on the shoulders and hips.
• Medium-Firm Mattresses: Provides extra support without compromising on comfort, often the most popular choice.
• Firm Mattresses: Strong support, recommended for back and stomach sleepers or heavier individuals.

Are Single Mattresses Suitable for Children and Adults?

Yes! Single mattresses work brilliantly for both children and adults, depending on your space and requirements. For adults, single mattresses are perfect for compact bedrooms, studio flats, or guest rooms where space is at a premium. They also suit solo adult sleepers who prefer the efficiency of a smaller mattress, as well as those furnishing spare rooms for occasional guests.

For children’s bedrooms, single mattresses provide ample sleeping space as they grow from toddler beds to teenage years. For more, take a look at our kids’ mattresses.

What’s the best single mattress for a bunk bed?

Choose a slimmer mattress, usually around 15 to 18cm deep, so the guard rail on the top bunk stays high enough. Always check the bed maker’s maximum mattress depth. Our bunk bed mattress thickness guide explains more.

What Is the Best Single Mattress to Buy?

There's no single best mattress, it depends on your firmness preferences, sleeping position, weight, and factors like whether you sleep hot or need pressure relief. Side sleepers often prefer memory foam, whilst back sleepers need firmer support. The right choice is whatever suits your body and budget.

What Does a Good Single Mattress Cost?

Prices vary depending on the filling, quality, and brand. Budget open coil single mattresses start lower, whilst memory foam, pocket sprung, and hybrid options cost more due to added layers and materials. Size, thickness, and any certifications (such as being eco-friendly or hypoallergenic) also affect price. Check our mattress sale offers for current single mattress deals.

How Long Does a Single Mattress Last?

A single mattress can last on average, 6-8 years. However, this depends on the type, quality, and usage of the mattress. Signs it's time for a new mattress include sagging, persistent discomfort, or poor sleep quality.
