Layer Details
Cover
A breathable stretch fabric cover. It flexes with the layers beneath, so you feel the foam's contouring rather than a taut surface.
Foam
High-performance ErgoSense foam relieves pressure and promotes healthy blood circulation, which means less tossing and turning to relieve numb spots. It's the layer that gives the mattress its medium, cushioned feel.
Springs
Individually pocketed springs, 1,000 of them in the king size, move independently rather than as one unit. That means better spinal alignment and less disturbance when a partner shifts in the night.
Support
DynamicEdge® active side support firms up the perimeter to maximise the usable sleep surface and prevent roll-off. Useful if you sit on the edge to dress, or share a smaller bed.

Key benefits
- Room left for everything else: At 90cm wide, the UK single leaves space for a wardrobe, a desk and toy storage in a child's bedroom, so the bed doesn't take over the floor.
- A firmer edge on a narrow bed: DynamicEdge® side support stiffens the perimeter, which matters more on a UK single because a child or teen will often sleep close to the side.
- Pressure relief for growing bodies: The ErgoSense foam cushions hips and shoulders, which means a teenager who sleeps on their side is less likely to wake with numb spots.
- Two beds in one spare room: Two UK singles can sit side by side with a walkway between them, giving guests or siblings a bed each rather than one shared bed.
- A balanced feel for mixed guests: The medium firmness sits in the middle, a sensible choice for a guest room when you don't know who will be sleeping in it.
This size suits you if...
You're kitting out a child's or teenager's bedroom where floor space is shared with a desk and storage, or you sleep alone in a compact room. It also suits a spare room that works as an office most of the week, or siblings who need a bed each.
Consider another size if...
You're an adult sleeping alone who spreads out, or you often share with a child or pet. We'd recommend the UK small double instead, which is 30cm wider; allow at least 2.4m x 2.8m.

FAQ's
Will the Sleep Story Ergo Deluxe UK single fit a bunk bed or mid sleeper?
The mattress is 23cm deep, which is a standard depth rather than a tall one. Raised frames usually set a maximum mattress depth so the guard rail stays high enough above the sleeping surface. Check the frame maker's guidance against that 23cm figure before ordering, especially for a top bunk or cabin bed.
What size room do I need for a Sleep Story Ergo Deluxe UK single?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open a wardrobe. In a loft conversion, a narrow 90cm footprint is easier to tuck under a sloping ceiling, although you'll want enough headroom to sit up comfortably.
Is a UK single Ergo Deluxe long enough for a tall teenager?
The UK single is 190cm long, the same length as the UK small double and UK double. A very tall teen may find their feet near the end. The UK king is 10cm longer than the UK single, but it's far wider, so most families stay with 190cm until growth makes the choice for them.
Does edge support matter on a single mattress?
Yes, arguably more than on a wide bed. On a 90cm UK single there's little spare width, so a sleeper often lies near the side. The DynamicEdge® perimeter on the Ergo Deluxe firms up that area, which means less of a roll-off feeling and a steadier edge for sitting on while dressing.
Should one adult buy the Ergo Deluxe in a UK single or a UK small double?
If you lie fairly still and your room is tight, the UK single works well. If you turn a lot or like to spread out, the UK small double is 30cm wider at the same length, though we suggest at least 2.4m x 2.8m of floor space for it.
