Key benefits
- Leaves floor space for play: A 90cm wide UK single takes up little of a small bedroom, which means space remains for a wardrobe, a desk or a box of toys.
- Fits standard single frames: It follows the standard UK single size of 90 x 190cm, so a cabin bed or divan built for a UK single should take it without gaps at the edges.
- Spills stay on the surface: The waterproof cover means a knocked-over drink or a night-time accident is far easier to deal with on a child's UK single.
- Room to grow into: At 6ft 3in long, a UK single gives a small child plenty of length, and most will still fit comfortably well into their teens.
- Breathable for a warm small room: The airflow border and recycled-fibre layer let air move through the mattress, which helps a little in a compact bedroom that warms up quickly.
This size suits you if...
You're buying a first proper bed for a child aged 3 or over, the room is small and has to hold storage or a desk as well, or you're fitting out a spare room that hosts visiting grandchildren.
Consider another size if...
You need a size other than a UK single, your child is under 3, or the bunk or mid sleeper you have in mind needs a slimmer mattress, as this one is 23cm deep.

FAQ's
What are the dimensions of the Silentnight Explore kids' mattress in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It is 23cm deep. Those are standard UK single dimensions, so frames and bedding sold as UK single should match without any guesswork.
Will the Explore UK single fit a bunk bed or cabin bed?
The width and length match any frame built for a standard UK single. Depth is the part to check. At 23cm, it may sit too high for some raised frames, where the guard rail needs to stay well above the mattress. Look up the frame maker's maximum mattress depth before you order.
How big does a bedroom need to be for a UK single kids' bed?
We suggest allowing at least 2.1m x 2.8m for a UK single. That leaves enough space to walk around the bed and open drawers. In a shared room with two beds, measure each footprint plus the walkway between them.
What bedding fits a UK single children's mattress?
Any fitted sheet sold as a UK single will suit the 90 x 190cm surface, and a single duvet measures 135 x 200cm. If you buy a separate waterproof protector, choose one sized for a UK single so it sits flat.
Is a UK single long enough for a teenager?
At 190cm, or 6ft 3in, a UK single gives most teenagers enough length. A medium feel suits most children as they grow, although a very tall teen may eventually find their feet close to the end and want a longer bed.
