Small Single Mattresses (2ft 6)

Why choose a small single mattress?

A small single mattress gives you a full 190cm sleeping length in a narrower 75cm width, making it ideal where space is limited. Its compact size can work particularly well for:

• Toddler transitions: A cosier step up from a cot, with extra room to wriggle as your child grows. Read our guide to Kids' Bed Sizes.

• Tiny box rooms: Save valuable floor space when fitting in essentials such as a desk, wardrobe or storage. See our Home Measuring Guide.

• Caravans and cabin beds: The 75cm width can be a practical fit for compact, bespoke or space-saving bed frames where a standard single may be too wide.

How to choose the right small single mattress

Start by checking that a 75 x 190cm small single mattress is the correct size for your bed frame. These compact mattresses can work particularly well with bunk beds, cabin beds and day beds, as well as in box rooms and smaller guest bedrooms.

Next, consider who will be using the mattress and how often. A small single can be a useful step up for toddlers moving on from a cot bed, while older children, guests and solo sleepers may also benefit from the space-saving dimensions. For an everyday bed, compare firmness, support and comfort layers carefully. For occasional use, a simpler construction may provide what you need.

You can also choose between different mattress types. Open coil mattresses tend to sit towards the more affordable end of the range, while pocket sprung mattresses offer individually moving springs for more responsive support. Memory foam provides closer, more cushioned comfort.

If the mattress is for a bunk bed, always check the bed manufacturer's maximum permitted mattress depth before ordering. A mattress that is too deep can reduce the effective height of the safety rail.

Finally, check the individual product page for delivery availability or warranty information and any other relevant details before you buy.

Buying guidance for small single mattresses

Choosing the right small single mattress starts with understanding the space you have and who will be using it. From children moving up from a cot bed to guest rooms and compact bedrooms, the right size, mattress type and firmness can make all the difference.

What size is a small single mattress?

A UK small single mattress measures 75 x 190cm, or 2ft 6 x 6ft 3. It is the same length as a standard UK single mattress but 15cm narrower, helping you make better use of limited bedroom space. A standard single measures 90 x 190cm.

That compact width makes a small single bed mattress particularly useful for box rooms, children's bedrooms and guest spaces. It can also fit compatible bunk beds, cabin beds and day beds, although you should always measure the frame and check the manufacturer's specifications before ordering.

Who is a 2ft 6 mattress best suited for?

A 2ft 6 mattress is a practical option when you want to preserve as much usable floor space as possible. It can suit toddlers moving up from cot beds, children with smaller bedrooms and occasional guests where a standard single would take up more room.

For adults, the narrower sleeping area means it is worth considering whether a standard single would offer more comfortable space if the room allows.

Small single, cot bed or standard single?

A small single gives you the full length of a standard single while saving 15cm across the width, making it a useful middle ground when a cot bed has been outgrown but bedroom space remains limited.

Ask the expert about small single mattresses

Choosing a mattress is easier when you know what to compare. Our product experts answer common questions about small single mattresses, including size, suitability, guest rooms, bedding and delivery.

Martin Seeley, Product Expert at MattressNextDay, answers questions about small single mattresses.

What is the difference between a small single and a standard single mattress?

A small single mattress measures 75 x 190cm, while a standard single is 90 x 190cm. Both are the same length, but the small single saves 15cm in width. This can make a noticeable difference in a box room, compact child's bedroom or guest room where you want to leave more space around the bed.

If you have enough room for a standard single, its wider sleeping surface may be preferable, particularly for an adult or older teenager using the bed every night.

Are small single mattresses suitable for children moving from a cot bed?

They can be a useful next step for toddlers and young children once they are ready for a larger bed. A 2ft 6 mattress provides considerably more sleeping length while taking up less floor space than a standard single.

Make sure the mattress dimensions match the new bed frame exactly and choose an appropriate firmness and construction for the child using it.

Can I use a small single mattress on a bunk bed or cabin bed?

Yes, provided the bed frame is specifically designed for a 75 x 190cm mattress. Small singles can be useful for compact bunk beds, cabin beds and other space-saving children's furniture.

For bunk beds in particular, check the manufacturer's instructions for the maximum permitted mattress depth. The mattress needs to sit low enough for the upper bunk's safety barrier to provide the intended level of protection. Do not assume every small single mattress will be suitable simply because its length and width match the frame.

Which type of small single mattress should I choose?

The right construction depends on the feel you prefer, how regularly the mattress will be used and your budget.

Pocket springs generally provide a more responsive feel, while memory foam offers closer cushioning. There is no need to pay for features that do not matter to you, so compare construction alongside firmness, intended use and price.

Are small single mattresses suitable for guest rooms?

Yes. A small single can be particularly useful in a compact guest room where fitting a standard 90cm-wide mattress would leave very little floor space.

Think about how frequently the bed will be used when choosing the mattress. An occasional guest bed may suit a simpler, better-value construction, while a bed used regularly may justify investing more in comfort layers and support. 

What bedding do I need for a small single mattress?

Choose bedding specifically sized for a small single or 2ft 6 mattress where available. In particular, check fitted sheets, mattress protectors and toppers against the mattress's 75 x 190cm dimensions and depth.

Mattress depth matters for fitted products, so check the measurements rather than assuming standard single bedding will fit neatly. You can also complete the bed with suitable pillows, duvets and other bedding accessories from the MattressNextDay range.

Can I get free next-day delivery on a small single mattress?

Free next-day delivery is available on eligible in-stock mattresses across the UK mainland, so check the individual small single mattress for current availability before ordering.

Where next-day delivery is available, it can be particularly convenient if you are replacing a mattress quickly, setting up a child's new bed or getting a guest room ready. Delivery options and availability can vary, so confirm the details shown at checkout for your chosen mattress.

Can an adult sleep on a small single?

Yes. Because the length (190cm) is exactly the same as a standard single or double bed, it will comfortably fit an average adult. It is simply a narrower sleeping surface, making it a great temporary solution for guest sleepovers in very tight rooms.
