Layer Details
Damask Cover
A breathable Belgian damask fabric cover. It lets air move through the surface, which means less heat building up around you overnight.
Comfort Layer
A generous polyester and cotton blend layer that cushions your body. It softens the surface slightly without compromising the firm feel underneath.
Soft White Fibres
Fibre fillings made from 100% polyester. These recover their shape well, which means the comfort layers should resist flattening over time.
Cotton
A natural filling that helps regulate body temperature. It also adds a touch of extra support and comfort.
Pocket Springs
Up to 1600 pocket springs that work independently, contouring to your body as you move. That means targeted pressure relief where you need it, and less disturbance from a partner shifting about.
High-density Support Layers
Dense support layers on both sides of this double-sided mattress. They add further pressure relief and let you flip the mattress to spread the wear.

Key benefits
- Room to spread out alone: At 30cm wider than the UK single, you can sleep diagonally or starfish on a firm, flat surface 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 bedroom door still opens freely in a box room or studio.
- Firm support for a growing teenager: A teenager who has outgrown a single gets a bed that will last into adulthood, and the extra width costs only a modest strip of floor.
- Copes with occasional guests: Up to 1600 independent pocket springs limit how much one guest's movement reaches the other, which helps when a visiting couple shares a narrower bed for a night or two.
- Same length as a double: At 4ft x 6ft 3in, it matches the UK double for length, so most adults under that height lie flat without their feet hanging over.
This size suits you if...
You sleep alone and want more width than a single allows, your bedroom is compact but meets our suggested minimum of 2.4m x 2.8m, or you are furnishing a guest room where couples stay occasionally rather than every night.
Consider another size if...
You share the bed with a partner every night and want space to settle without touching. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m.

FAQ's
What room size do I need for a UK small double Sleepeezee Ortho Firm 1600?
We suggest allowing at least 2.4m x 2.8m. The mattress itself measures 120 x 190cm, and that room guidance leaves space to walk around the bed and open doors. In a tighter box room, measure the door swing as well as the floor before you order.
Is the Sleepeezee Ortho Firm 1600 small double better than a single for a teenager?
If floor space allows, it usually is. The UK small double is 30cm wider than the UK single and the same length, so it gives a teenager more room without needing a bigger room. A UK single needs at least 2.1m x 2.8m by our guidance. Lightweight teenagers who sleep on their side may find this mattress too hard.
Can a couple use the Ortho Firm 1600 small double for occasional stays?
Yes, for the odd night it works well in a guest room. The independent pocket springs help limit disturbance when one person turns over. For couples sharing every night, the UK double gives 67.5cm each, and we suggest at least 2.6m x 2.8m for it.
Is the UK small double Ortho Firm 1600 long enough for tall sleepers?
It is 190cm long, or 6ft 3in, the same length as the UK double. If you are close to that height or taller, the UK king is 10cm longer, though it needs at least 2.7m x 2.9m by our guidance.
Is a small double Ortho Firm 1600 easier to flip than the bigger sizes?
At 120cm wide, it is a narrower mattress to turn than the UK king or UK super king, which helps because this double-sided mattress should be flipped regularly. Sleepeezee's own handling guidance is worth checking before you try it alone, particularly in a small room with little space to manoeuvre.
