Layer Details
Cover
A knitted micro quilted cover, which means the top surface has a soft, slightly cushioned texture stitched into it. It adds a touch of surface comfort without a separate pillow top.
Fillings
100% polyester fibre fillings sit between you and the springs. These give a simple, breathable comfort layer, though they won't contour to your body the way memory foam would.
Springs
1000 individual pocket springs form the support core, part of Silentnight's Mirapocket system. Each spring is sewn into its own fabric pocket, so it responds to pressure independently and reduces the ripple effect when someone else moves.

Key benefits
- Real space for one: At 30cm wider than the UK single, it suits an adult or teenager who has outgrown a single bed but sleeps alone most nights.
- Fits compact rooms: Being 15cm narrower than the UK double can be the difference between a door that clears the bed frame and one that doesn't in a box room or studio.
- Sensible for guest rooms: Couples can share it for the odd weekend, and the 1000 pocket springs limit motion transfer if two people do end up on it.
- Springy, breathable feel: Polyester fibre fillings over pocket springs keep the surface simple and airy, a practical match for a spare room that runs warm in summer.
- Easy to kit out: 4ft is a standard UK size, so small double fitted sheets and frames are straightforward to find on the high street.
This size suits you if...
You sleep alone but want more width than a UK single gives, perhaps a teenager moving up from their first bed, or an adult in a rented flat where the room simply won't take a bigger frame. It also makes sense for a guest room that hosts couples occasionally rather than every night, at a spec you won't resent paying for on a bed used a few weekends a year.
Consider another size if...
You share the bed every night; 120cm is a squeeze for two adults long term. We'd recommend the UK double instead, which is 15cm wider and the same length, and needs a room of at least 2.6m x 2.8m.

FAQ's
Will a small double mattress fit in a box room?
Usually, yes. The UK small double is 120 x 190cm, and we suggest a room of at least 2.4m x 2.8m so you can still open the door and move around the bed. Measure the wall the headboard will sit against and check the door swing before ordering, especially in a loft conversion.
Is the Silentnight Pocket Essentials 1000 small double good for couples?
For occasional nights, yes. The 1000 individual pocket springs respond to each sleeper separately, so one person turning over is less disruptive. For every night, two adults on 120cm of width will feel cramped; the UK double, 15cm wider at the same length, is the better long-term choice.
How much bigger is a small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is the whole point of the size: a solo sleeper gets proper room to spread out without stepping up to a full double footprint.
What bedding do I need for this small double mattress?
Small double, or 4ft, fitted sheets are the correct fit for the 120 x 190cm surface. For the top layer, a standard double duvet works well and gives a generous overhang on each side. Both are stocked as standard UK sizes, so you won't be hunting for specialist bedding.
Where can I buy the Pocket Essentials 1000 in a small double?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so it's worth a quick check before you commit. Stock and pricing for the UK small double can differ from the other four sizes, so don't assume the cheapest seller of one size is cheapest for all.
