Layer Details
- Cover. A breathable Belgian damask fabric cover, which means air can move through the sleep surface rather than trapping warmth against you. It's a traditional, hard-wearing choice.
- Comfort Fillings. Soft white fibre fillings made from 100% polyester. These give a gentle cushioned feel over the springs, though they're simpler than the foam layers found on pricier mattresses.
- Support System. 1,000 individually pocketed springs, each mounted in its own separate fabric pocket so they work completely independently of one another. In practice, that means support follows your body's contours and your partner's movements are less noticeable.

- Leaves room for everything else: At 3ft wide, the UK single frees up floor for a desk, wardrobe and toy boxes, and we suggest a room of at least 2.1m x 2.8m.
- Support that follows a growing frame: Each of the 1,000 springs sits in its own pocket, which means the mattress responds to a child or teen's shape rather than dipping as one block.
- Two singles for a flexible guest room: A pair of UK singles lets visiting friends sleep separately, and each pocket sprung mattress moves independently of the other.
- Firm enough for a young sleeper: The medium firm feel gives children and teenagers steady, traditional support, although lighter side sleepers may find the thin fibre fillings a little firm at the hips.
- Suits a room under a sloping ceiling: The narrow 90cm footprint tucks under the low side of a loft conversion, leaving the taller part of the room free for standing and storage.
This size suits you if...
You're buying for a child or teenager whose room also has to hold a desk and storage, or you're kitting out a spare room or loft conversion where floor space is tight. It also suits a single adult under average height who wants firm, dependable pocket spring support.
Consider another size if...
You're an adult who sprawls, or you'd like space for a partner or pet some nights. We'd recommend the UK small double instead, which is 30cm wider; allow at least 2.4m x 2.8m.

Can I put a Spring King Madrid 1000 single on a bunk or mid sleeper?
The Madrid 1000 is 25cm deep, which is deeper than many budget mattresses. Raised frames usually set a maximum mattress depth so the guard rail stays high enough above the sleeper. Check your bunk, cabin or mid sleeper's own guidance before buying, as a 25cm mattress may exceed what some frames allow.
How much room do I need for the Madrid 1000 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk past the bed and open drawers or a wardrobe, which matters in a child's bedroom where furniture competes for every bit of floor.
Is a UK single Madrid 1000 long enough for a tall teenager?
The UK single is 190cm long. For most teens that is fine, but a tall teenager who is still growing may soon find their feet near the edge. The UK king is 10cm longer; we suggest at least 2.7m x 2.9m for it, so it needs a much bigger room.
Madrid 1000 single or small double for a teenager's room?
The UK single is 30cm narrower than the UK small double, and both are the same length. If the room can take it, a UK small double gives a teenager more space to spread out; we suggest at least 2.4m x 2.8m for it. In a smaller box room, the UK single leaves more floor free.
Does the Madrid 1000 single work as a spare bed in a home office?
Yes, in most cases. A UK single takes up less wall space than any larger size, so a desk can sit alongside it. The medium firm pocket springs give guests steady support, although anyone who likes a deep, cushioned feel may find the simple polyester fibre fillings a little thin.
