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
- Leaves floor space free: At 90cm wide, the UK single leaves room for a desk or wardrobe beside it, which matters in a box room where every spare metre is already spoken for.
- Fits under a sloping ceiling: The narrow footprint lets you tuck the bed along the low wall of a loft conversion and still keep standing room on the open side.
- Two can share a guest room: Two UK singles side by side give visitors separate beds, and the pocket springs keep each surface supportive for whoever sleeps on it.
- Flipping is more manageable: This double-sided mattress needs turning, and the UK single is the smallest version of it, so the job is a little easier if one person does it alone.
- Firm support for a teenager who wants it: If an older teen or student finds softer beds leave their back aching, the firm feel gives them the solid support they are asking for in a size their room can take.
This size suits you if...
You sleep alone and prefer a genuinely firm bed, your bedroom is small or has a sloping loft ceiling, or you are kitting out a spare room with two beds for guests who like solid support.
Consider another size if...
You share the bed, or you are a light sleeper or young child who finds firm beds hard. For two sharing, we'd recommend the UK double, which gives 67.5cm each; we suggest at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Ortho Firm 1600 UK single suitable for a child?
It can be, although many children are lightweight and may find an extra firm surface a little too hard at the shoulder and hip. It suits an older child or teenager who already prefers firm beds better. If your child likes to sink in, a softer mattress in a UK single would probably make them more comfortable.
Will a UK single Sleepeezee Ortho Firm 1600 fit a bunk bed or mid sleeper?
The UK single matches the 90 x 190cm size most bunks and mid sleepers take, but at 28cm deep this mattress is thicker than many raised frames allow. Check your frame's maximum mattress depth and the guard rail height before buying, because a deep mattress can leave the rail too low to be safe.
What size room do I need for a UK single Ortho Firm 1600?
We suggest allowing at least 2.1m x 2.8m of floor space for the UK single. That leaves room to get in and out comfortably and fit a small bedside table or desk. In a room shared by siblings, measure for both beds and a walkway between them before you order.
Is the UK single Sleepeezee Ortho Firm 1600 easy to flip on your own?
It is the smallest size of this double-sided mattress, so it is the most manageable one to turn. Regular flipping spreads the wear across both sides. If you will be doing it alone, stand the mattress on its long edge first, then lower it over, rather than trying to lift it flat.
Should I get a UK single or UK small double Ortho Firm 1600 for a spare room?
The UK single is 30cm narrower than the UK small double and the same length. Choose the UK single if you want two separate guest beds or have a tight room. The UK small double suits one adult who wants more room to spread out, and we suggest at least 2.4m x 2.8m for it.
