Layer Details
Comfort Layer
Soft white fibre fillings sit at the surface, which means a cosy, slightly cushioned feel over the firmer springs beneath. It is a simple comfort layer rather than a deep plush one.
Support System
800 individual pocket springs, each sitting inside its own fabric pocket, move independently. In practice that means support tailored to your shape and less motion transferred across the bed when a partner moves.
Cover
A damask cover, a finely woven and durable fabric that feels soft to the touch. Woollen tufts pass through the mattress to keep the fillings from shifting over time.

Key benefits
- Room to spread out alone: The UK small double is 30cm wider than the UK single, which means a solo sleeper can turn over or lie starfish without an elbow drifting off the edge.
- Leaves space in a tight room: Being 15cm narrower than the UK double, the UK small double can keep enough clearance for a wardrobe door or bedroom door to swing open in a box room.
- Calmer for the odd shared night: The 800 pocket springs move independently, which means a visiting couple feel a little less of each other shifting during a weekend stay.
- Firm support for a growing teenager: The medium firm tension suits a teenager on their back or front, although a slim side sleeper may find the shoulders and hips feel slightly pressured.
- Simple to kit out: A 4ft frame and small double fitted sheets are standard UK items, so furnishing a guest room or a teenager's room around this mattress is straightforward.
This size suits you if...
You sleep alone and find a single too narrow, a teenager in your house has outgrown their single but the bedroom cannot spare much floor, or you are furnishing a guest room where couples stay only now and then.
Consider another size if...
You share the bed with a partner every night, as the UK small double gets cramped for two adults. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m.

FAQ's
Will the Sleepeezee Classic Ortho 800 small double fit in a box room?
We suggest a room of at least 2.4m x 2.8m for the UK small double. Measure where the door swings and where any wardrobe opens before you order, because on a tight floor plan it is often clearance around the bed, rather than the mattress itself, that decides whether the room still works day to day.
Is the Classic Ortho 800 in a small double good for a teenager?
It suits a teenager moving up from a single well if they sleep on their back or front, as the medium firm pocket springs give steady support. A lightweight teenager who sleeps on their side may find it a little firm at the shoulder. The UK small double also keeps more floor free than a UK double.
Sleepeezee Classic Ortho 800 small double or single for one adult?
The UK small double is 30cm wider than the UK single and the same length, so the extra is all in width for turning over. If your room is smaller, the UK single needs less floor: we suggest at least 2.1m x 2.8m for the UK single, against 2.4m x 2.8m for the UK small double.
Can guests share a Classic Ortho 800 small double for a weekend?
For a night or two, yes. The independent pocket springs help limit movement across the bed. Across owner reviews some mention wanting firmer edges, and on a narrower mattress couples tend to sleep closer to the sides, so a guest who likes the outer edge may notice it a little more.
Is the Classic Ortho 800 small double long enough for tall sleepers?
The UK small double is 190cm long, the same as the UK double. If your feet reach the end, the UK king is 10cm longer, although it also needs more room: we suggest at least 2.7m x 2.9m for the UK king.
