Key benefits
- Leaves room for everything else: At 90cm wide it fits in a child's bedroom alongside a wardrobe and desk, and we suggest at least 2.1m x 2.8m of floor space.
- Easy to clean after accidents: The water repellent surface means a spilt drink or a bedwetting night can be wiped up, and the removable cover washes at 40 degrees.
- Firm support for a growing child: The firm open coil build keeps a child lying on top of the mattress rather than sinking in, which tends to suit back and front sleepers.
- Cheap, easy bedding: Standard single sheets fit, along with a single duvet at 135 x 200cm, the most widely stocked bedding size of all.
- Kind to sensitive skin: The anti-allergy, hypoallergenic cover fabric is PVC free, which helps if your child has allergies or reacts to synthetic coatings.
This size suits you if...
You're furnishing a child's or teenager's bedroom where the bed has to share floor space with storage and a desk, or you're kitting out a spare room or student room for one person who likes a firm surface. It also suits a parent who wants a mattress that copes with accidents.
Consider another size if...
Two people need to share the bed, the sleeper is a side sleeper who wants soft cushioning at the shoulders and hips, or you want a soft or medium feel.

FAQ's
Will the Over The Moon UK single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK single bunk and mid sleeper frames. Little Big Dreams doesn't publish a depth for this mattress, though, and raised frames usually set a maximum mattress depth so the guard rail stays effective. Check the frame maker's guidance and confirm the depth with the retailer before ordering.
How much floor space does a UK single mattress need?
We suggest allowing at least 2.1m x 2.8m. That gives room to walk round the bed and open drawers or a wardrobe door. In a shared children's room with two singles, leave a clear walkway between the beds.
Is a UK single big enough for a teenager?
For width, usually yes: 90cm is comfortable for one person. The length is 190cm, or 6ft 3in, so a very tall teenager may find their feet near the end. The firm feel suits teens who sleep on their back or front.
Can two children share the Over The Moon UK single?
We wouldn't recommend it. At 90cm wide the UK single is designed for one sleeper, and two children will disturb each other. The Over The Moon is made in the UK single only, so in a shared room the usual answer is two separate single beds.
What bedding fits a UK single Over The Moon mattress?
Standard UK single fitted sheets fit the 90 x 190cm surface, and a single duvet measures 135 x 200cm. Because Little Big Dreams doesn't publish a depth, check that deep-pocket sheets aren't needed before you buy a stock of them.
