Layer Details
Knitted cover with Microquilted finish
A soft knitted cover with a micro-quilted finish, which means a smooth surface with a little added cosiness and warmth.
Memory Foam
Memory foam cradles to your shape, which means a cushioned, cosy feel as soon as you lie down. It's the layer that gives this mattress its softer top comfort.
Soft White Fibres
Soft synthetic fillings add to the cosy feel while staying durable and resilient. They're designed to hold their shape over time rather than compacting quickly.
Mini Pocket Springs
Small, individually cased springs sit above the main spring unit, adding comfort and gentle pressure relief. They also help reduce motion transfer, so you'll feel less of a partner's movement.
Pocket Springs
1,800 traditional pocket springs, each encased in its own cloth pocket, adapt independently to your movement. This gives personalised support across the whole surface rather than the mattress moving as one piece.

Key benefits
- Room to spread out alone: The UK small double is 30cm wider than the UK single at the same length, which means space to turn over without an arm dropping off the edge.
- Keeps a small room usable: Being 15cm narrower than the UK double can decide whether a wardrobe door or the bedroom door still swings open freely in a box room or studio.
- Calmer for the odd shared night: The mini pocket springs above the main unit reduce motion transfer, which helps on a narrower bed where a visiting partner lies close beside you.
- Fits a standard 4ft frame: At 4ft x 6ft 3in, it drops into a common UK frame size, so replacing a tired mattress on an existing bed stays simple.
- Suits a loft conversion: A narrower footprint can leave you a strip of floor to stand on beside the bed where a sloping ceiling rules out anything bigger.
This size suits you if...
You sleep alone most nights and want more width than a single allows, your bedroom is a box room, studio or loft conversion where every centimetre of floor counts, or a partner stays over occasionally rather than every night.
Consider another size if...
You share the bed every night and want room to yourselves. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Is the Sleepeezee Luxury Ortho 1800 UK small double big enough for two people every night?
It works for occasional stays, and the mini pocket springs help limit a partner's movement. For nightly sharing it feels a little close, though. The UK double is 15cm wider at the same length and gives 67.5cm each, so couples sleeping together every night would be more comfortable on the UK double.
What size bedroom do I need for a UK small double Sleepeezee Luxury Ortho 1800?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to get in and out and to open doors. If your room is smaller than that, measure the door swing and any furniture before ordering.
Should a teenager move from a single to a UK small double Sleepeezee Luxury Ortho 1800?
It's a sensible step up if the room can take it. The UK small double is 30cm wider than the UK single but the same length, so it adds width rather than legroom. The medium firm hybrid feel suits most growing sleepers, and the bedroom still keeps a reasonable amount of floor.
Will the Sleepeezee Luxury Ortho 1800 small double fit my 4ft bed frame?
A UK small double is 4ft x 6ft 3in, or 120 x 190cm, which matches a standard 4ft frame. Check your frame's internal measurements first, as some older or imported frames run slightly differently to current UK sizing.
Is the Sleepeezee Luxury Ortho 1800 UK small double long enough for a tall person?
The UK small double is 190cm long, the same as the UK single and UK double. If you're tall and your feet already reach the end of the bed, the UK king is 10cm longer, although it's also 30cm wider, and we suggest at least 2.7m x 2.9m for the UK king.
