Layer Details
Damask Cover
A breathable cover made from Belgian damask fabric. Breathability here means air can move through the surface, which helps the mattress feel less stuffy on warm nights.
Polyester and Wool Blend
A comfort layer blending polyester with wool, which is naturally temperature regulating. In practice that means it helps even out warmth rather than trapping heat against you.
Soft White Fibres
Fibre fillings made from 100% polyester, chosen for recovery and durability. They spring back into shape after use, which helps the surface resist dips over time.
1000 Pocket Springs
Up to 1000 springs, each pocketed so it works completely independently of the others. This gives targeted support and reduces the ripple you feel when a partner moves.

Key benefits
- Room to spread out on your own: The UK small double is 30cm wider than the UK single, which means you can sleep with your elbows out while the firm surface keeps you level.
- Suits a compact double bedroom: We suggest a room of at least 2.4m x 2.8m, so the UK small double can go into a box room or loft conversion where a double would crowd the door.
- Firm support across the whole surface: The springs are individually pocketed, which means each one responds to your weight on its own, so you get even support wherever you settle on the mattress.
- Fine for an occasional couple: Two people can share for a weekend, and the independent springs soften the jolt when one of you turns, although sharing every night would feel a little tight.
- Simple to kit out: Because 4ft is a standard UK width, finding a frame and small double fitted sheets is easy, and a standard double duvet gives you generous cover.
This size suits you if...
You sleep alone and like a firm bed that keeps your back level, and you have outgrown a single in a room that cannot spare much floor, or a partner only stays the odd weekend.
Consider another size if...
You share the bed every night and want room to move without touching. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Ortho Firm 1000 small double a good upgrade for a teenager?
Yes, if the teenager has started to feel squeezed on a single. The UK small double is 30cm wider than the UK single but the same length, so it takes up only a little more floor. The firm feel suits teenagers who sleep on their back or front, though a slight side sleeper may find it too unyielding.
Will a small double Ortho Firm 1000 fit in a loft conversion bedroom?
Often, yes. We suggest a room of at least 2.4m x 2.8m for a UK small double. In a loft conversion, measure the area where you can stand upright, because you need space to get in and out of the side. The UK small double's 120cm width leaves more of that standing room clear than a double would.
Is the Ortho Firm 1000 in a small double comfortable for guests who come as a couple?
For the odd night or weekend, most couples will manage. The pocketed springs move independently, so you feel less of your partner turning over. For guests who stay for longer spells, the UK double gives 67.5cm each for two sharing and needs a room of at least 2.6m x 2.8m.
Should I choose the Ortho Firm 1000 in a small double or a double for a small bedroom?
The UK small double is 15cm narrower than the UK double and the same length. We suggest at least 2.4m x 2.8m for the UK small double and 2.6m x 2.8m for the UK double. If you sleep alone, the UK small double keeps more of the room free. If you share nightly, the UK double is the better fit.
Is the Sleepeezee Ortho Firm 1000 small double long enough if you're tall?
The UK small double is 190cm long, or 6ft 3in, which suits most adults. If your feet already reach the end of your current bed, the UK king is 10cm longer than the UK small double. For the UK king, we suggest a room of at least 2.7m x 2.9m.
