Layer Details
Knitted Cover
A soft knitted cover that breathes well, which means heat is less likely to build up around you overnight. It should help keep your temperature fairly even until morning.
Reflex Foam
A generous layer of reflex foam that contours to your shape, cushioning your frame at every curve. You feel this as gentle give at pressure points rather than a deep sink.
Open Coil Springs
An open coil system made from high-tensile steel joined in a lattice shape, giving medium tension support across your whole body. Open coils move together as one unit, so expect a slightly bouncier, more connected feel than pocket springs.

Key benefits
- Leaves room for everything else: At 90cm wide, the UK single frees up floor space for a wardrobe, a desk and toy storage, which matters in a child's bedroom where every wall already has a job.
- Two can share a guest room: A pair of UK singles lets a spare room take two guests who would rather not share a bed, with a walkway left between them in a room of reasonable size.
- A manageable depth for raised frames: The Premier is 22cm deep, which you can check against the maximum mattress depth your bunk, cabin or mid sleeper maker specifies before you order.
- No shared-bed drawback: Open coils move as one connected unit, which can disturb a partner in bigger sizes, but in a UK single there is nobody else on the mattress to feel it.
- Enough length for most teenagers: The 190cm length, 6ft 3in in imperial, gives a growing teenager room to stretch out without you needing a longer frame.
This size suits you if...
You are furnishing a child's or teenager's room where the bed has to share space with a desk and storage, or you are fitting out a bunk, cabin bed or mid sleeper. It also suits you if you need a sensible bed for a spare room that works as a study most of the year.
Consider another size if...
You are an adult who sprawls or turns a lot and finds 90cm cramped. We'd recommend the UK small double instead: it is 30cm wider, and we suggest at least 2.4m x 2.8m.

FAQ's
Is the Spring King Premier UK single a good mattress for a child?
For most children, yes. The medium feel and open coil support suit a lighter body, and the 90 x 190cm UK single fits standard single bed frames. The breathable knitted cover helps with kids who run warm. A lightweight child who sleeps on their side may find it a little firm, although most children adapt quickly.
Can I put a Spring King Premier single on a bunk bed or mid sleeper?
Often, yes, but check the frame first. The Premier is 22cm deep, and raised frames usually set a maximum mattress depth so the guard rail stays high enough to be safe. If your bunk maker's limit is lower than 22cm, choose a slimmer mattress for the top bunk.
What size room do I need for a Spring King Premier UK single?
We suggest allowing at least 2.1m x 2.8m for a UK single. That leaves space to walk around the bed and open a wardrobe door. In a loft conversion, a UK single's narrow footprint can sit along a low wall, provided there is enough headroom to sit up at the side you get out on.
Is the Spring King Premier UK single worth it for a guest room?
For occasional guests, it is a sensible choice. The budget price and medium feel suit a bed used a few nights a month, and two UK singles give visiting friends or siblings a bed each. If guests stay for weeks at a time, a deeper, softer mattress may keep them more comfortable.
Should I buy the Spring King Premier in a UK single or a UK small double?
Choose the UK single if floor space is tight or the bed is for a child. The UK small double is 30cm wider and the same length, which gives an adult more room to turn over, but we suggest at least 2.4m x 2.8m for it compared with 2.1m x 2.8m for the UK single.
