Layer Details
Wool
Natural wool fibres with temperature regulating properties, which means the mattress helps you stay cool in summer and warm in winter. Wool is a genuinely useful top layer for anyone who runs hot at night.
Cotton
Natural cotton fibres keep the sleeping surface fresh, regulating body temperature and wicking away moisture. In practice, this means a drier, more breathable feel than all-synthetic comfort layers.
Soft White Fibres
Soft synthetic fillings that create a cosy, cushioned feel. They're durable and resilient, so the layer should hold its shape rather than flattening quickly.
Pocket Springs Support System
5000 pocket springs made from twice tempered steel, each encased in its own fabric pocket so it moves independently. That means support that follows your body's shape, with less motion transfer across the bed.

Key benefits
- Suits lighter bodies: The medium soft feel gives easily under a child or slim teenager, which means they sink into gentle cushioning rather than lying on top of a hard surface.
- Leaves room for the rest: At 90cm wide, the UK single leaves floor space for a desk, wardrobe or toy storage, and we suggest allowing at least 2.1m x 2.8m.
- Breathable for warm rooms: Wool and cotton fillings help move moisture away, which helps in a small bedroom or loft conversion where warm air tends to gather.
- Pairs well for guest rooms: Two UK singles side by side let guests sleep separately, and the 5000 independent pocket springs keep each person's movement on their own mattress.
- Cheapest bedding to buy: A standard single duvet at 135 x 200cm fits, so kitting out a child's or guest bed stays simple.
This size suits you if...
You're buying for a child or teenager who sleeps alone and prefers a softer, cushioned bed, or you're furnishing a compact spare room or study where a slim footprint matters more than width.
Consider another size if...
You share the bed, or you're a heavier adult who spreads out. We'd recommend the UK small double instead, which is 30cm wider; allow at least 2.4m x 2.8m.

FAQ's
Will the Deluxe Naturals 5000 UK single fit a bunk bed or mid sleeper?
The UK single matches standard single frames at 90 x 190cm, but this mattress is 29cm deep, which is on the thicker side for raised beds. Many bunk and cabin frames set a maximum mattress depth so the guard rail stays high enough. Check the frame maker's guidance before buying for an upper bunk.
Is the Deluxe Naturals 5000 UK single good for a child?
For most children, yes. Lighter bodies suit a medium soft feel, and the wool and cotton fillings help stop a child overheating in a small room. The one flaw is longevity for bigger teenagers: a heavier teen who sleeps on their back or front may start wanting firmer support.
Can two people share a UK single mattress?
Not comfortably. The UK single is built for one sleeper, and two adults would have very little space each. For nightly sharing, the UK double gives 67.5cm each and is 45cm wider than the UK single; we suggest a room of at least 2.6m x 2.8m for it.
Does a UK single Deluxe Naturals 5000 suit a loft conversion bedroom?
It often does. The narrow 90cm footprint lets you tuck the bed along the low side of a sloping ceiling and keep the tall section free for standing. Allow at least 2.1m x 2.8m of floor space, and measure headroom where you'll sit up in bed.
Should I buy two UK singles or one bigger bed for a guest room?
Two UK singles give you more options: friends or siblings can sleep apart, and you can push them together for a couple. The softer feel suits most occasional guests. The prices shown here are updated as retailers change them, so compare before buying a pair.
