Fillings
High-density polyester layers sit at the top, which means a resilient comfort surface that resists dipping over time. It won't feel plush, but on a firm mattress that's rather the point.
Springs
Beneath the fillings sit 1,400 individually pocketed springs in the king size, each responding independently to your body shape and weight. In practice that means targeted support and less motion carrying across the bed to a partner.

Key benefits
- Leaves room for everything else: At 3ft x 6ft 3in, the UK single leaves space for a desk and wardrobe in a small bedroom, and we suggest at least 2.1m x 2.8m.
- Firm support for a growing back: The firm pocket springs suit teenagers who sleep on their back or front, although a lightweight child who curls up on their side may feel a little pressure at the hip.
- Easier to turn than the bigger sizes: This double-sided mattress needs turning through the year, and the UK single is the smallest size in the range, so it is the most manageable one to flip.
- Reassuring for allergy-prone rooms: Hypoallergenic certification and a cotton cover make it a sensible pick for a child's room or a guest who reacts to dust.
- Works as a pair in a guest room: Two UK singles side by side let guests who share the room sleep on separate surfaces, which suits friends, siblings or a visiting parent and child.
This size suits you if...
You sleep alone and like a properly firm surface, you're furnishing a child's or teenager's room where floor space is tight, or you're setting up a spare room or loft conversion where a narrow bed has to fit under the slope.
Consider another size if...
You're an adult who sprawls or turns a lot, or you're outgrowing 90cm of width. We'd recommend the UK small double instead: the UK single is 30cm narrower, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Is the Sleepeezee Ortho Legacy 1400 single too deep for a bunk bed?
It might be. The mattress is 30cm deep, and many bunk, cabin and mid sleeper frames set a maximum depth so the guard rail stays high enough above the sleeper. Check the frame manufacturer's stated limit before ordering. If your frame allows a shallower mattress only, this model is better suited to a standard divan or bedstead.
What size room do I need for a UK single Ortho Legacy 1400?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves you a sensible walkway and room to open drawers, which matters in a child's bedroom that also has to hold a wardrobe, desk and toy storage.
Is a UK single Ortho Legacy 1400 big enough for an adult?
For many single adults, yes: it measures 90 x 190cm, or 3ft x 6ft 3in. Taller sleepers may find the length a little short, since the UK single is 10cm shorter than the UK king. If you mainly want more width, the UK small double is the next step up.
Can one person turn a single Sleepeezee Ortho Legacy 1400?
More easily than any other size of this mattress, because the UK single is the smallest in the range. The 30cm depth still makes it a solid lift, so a second pair of hands helps. Sleepeezee doesn't publish a weight for the single, so check with the retailer if lifting is a concern.
Should a teenager have a single or small double Ortho Legacy 1400?
A UK single suits a teenager in a smaller room. If they are tall, restless or the room allows it, the UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m for that size. Compare the retailers listed on this page for current prices of each.
