Layer Details
- Soft-touch damask cover. A woven damask fabric cover, which means a traditional, hardwearing sleep surface rather than a plush knitted one. It keeps the top of the mattress smooth and practical for a child's bed.
- Insulator pad. This sits between the cover and the springs, which means you feel a cushioned surface rather than the coils beneath. It is a standard comfort barrier in open coil designs.
- Open coil spring unit. A single interconnected spring system that gives a soft, slightly springy feel across the whole mattress. It suits lighter sleepers well, although it offers less motion isolation than pocket springs, which matters little in a child's single bed.

- Made for lighter sleepers, in the size they use: The soft open coil feel is designed around children's lighter weight, and the UK single is the size nearly every child's bed frame takes.
- Low profile for raised frames: At 18cm deep, it sits below the safety rail line on most bunk beds and mid sleepers, where a taller mattress would be unsafe.
- Leaves floor space in a small room: A 90cm width keeps room free for a desk, wardrobe and toy storage in a child's bedroom that has to do several jobs at once.
- Fits two beds in a shared room: Where siblings share, two UK singles plus a walkway fit in rooms where anything wider simply would not.
- Cheap, easy bedding: Single fitted sheets and duvets are the most widely stocked and lowest priced of any size, and the 18cm depth means standard sheets go on easily.
This size suits you if...
You're buying for a child's bed, bunk bed or mid sleeper and want a soft, low-cost mattress in the standard 90 x 190cm size, or you need a slim second single for a shared kids' room where space is tight. It also works where a school or student let has provided a single frame and you only need the mattress to go on it.
Consider another size if...
Your child is a teenager approaching adult weight, or you want room for them to grow into. The Capsule Essentials also comes in a UK double, which is 45cm wider and the same length; we suggest at least 2.6m x 2.8m of floor space for the UK double.

Will the Capsule Essentials UK single fit a bunk bed?
In most cases, yes. Bunk beds and mid sleepers take a standard 90 x 190cm UK single, which is exactly this mattress's footprint, and its 18cm depth is slim enough to keep the guard rail doing its job on the top bunk. Check your frame's stated maximum mattress depth before buying, as a few models specify less.
Is the Capsule Essentials UK single big enough for a teenager?
For size, a UK single at 90 x 190cm suits most teenagers; it is the standard one-person size. The bigger question is weight: this is a soft children's mattress with an open coil unit, so a heavier teen may find it lacks support. For a lighter teenager it should be fine for a few more years.
How much room does a UK single mattress need?
We suggest at least 2.1m x 2.8m of floor space for a UK single, which leaves enough room to walk alongside the bed and open drawers or a wardrobe. At 90cm wide, it is the easiest full-length mattress to fit into a boxy child's room or under the slope of a loft conversion.
Can two Capsule Essentials singles fit in a shared kids' room?
Often, yes. Each mattress is 90cm wide, so two beds side by side or against opposite walls will fit in many shared rooms with a walkway between them, though it depends on your room's shape. The open coil springs matter less here than in a shared bed, since each child has their own mattress.
What bedding do I need for the Capsule Essentials in a UK single?
Standard UK single bedding: a 90 x 190cm fitted sheet and a single duvet, which measures 135 x 200cm. Because the mattress is 18cm deep, you won't need extra-deep fitted sheets, so the cheapest standard single sheets will fit properly rather than ballooning or slipping off at the corners.
