Key benefits
- Real width for one sleeper: At 120cm across, this size gives a solo adult 30cm more width than a UK single, which means you can starfish without a limb hanging off the edge.
- Fits compact double bedrooms: Being 15cm narrower than a UK double, it can be the difference between a door that opens fully and one that clips the bed frame.
- Pocket springs across the full width: The 1000 Mirapocket springs support the whole 120cm surface independently, so a sleeper who drifts to the edge still feels even support rather than roll-off.
- Memory foam without the enclosed feel: The body moulding memory foam layer cushions hips and shoulders wherever you settle on the wider surface, while the springs keep movement easy.
- Easy bedding and frames: 4ft is a standard UK size, so small double fitted sheets and frames are simple to find, and a standard double duvet drapes generously over it.
This size suits you if...
You're a solo adult who has outgrown a UK single but can't spare the floor space a full double demands, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're kitting out a teenager's room where 120cm of bed leaves enough space for a desk. The Medium/Firm feel suits back and stomach sleepers particularly well at this size.
Consider another size if...
You share the bed every night, because 120cm gets snug for two over time. The UK double of this mattress is 15cm wider and the same length; allow at least 2.6m x 2.8m for it.

FAQ's
Is a small double big enough for the Silentnight Comfort Pocket Essentials to suit a couple?
For occasional nights, yes. At 120 x 190cm the small double works well for guest rooms where couples stay now and then. For nightly sharing it gets tight, and the Medium/Firm surface means neither of you sinks toward the middle, but we'd still suggest the UK double, which is 15cm wider, for full-time couples.
What room size do I need for a small double Silentnight Comfort Pocket Essentials?
We suggest allowing at least 2.4m x 2.8m. That leaves enough clearance to walk around the bed and open drawers or a wardrobe. In a box room or loft conversion, measure where the ceiling slopes and where the door swings before you commit, since the 120cm width is often what decides whether the room still functions.
Is the small double the same length as a single?
Yes. The UK small double and the UK single are both 190cm long; the small double is 30cm wider. So if a single frame already fits your room lengthways, a small double will too, provided you can find the extra width. Taller sleepers wanting more legroom would need the UK king, which is 10cm longer.
Does the Silentnight Comfort Pocket Essentials feel different in a small double?
The feel is the same in every size: Medium/Firm, with memory foam over 1000 Mirapocket springs. What changes is how you use the surface. A solo sleeper on 120cm can shift position freely, and the pocket springs respond to your weight wherever you land, rather than transferring movement across the mattress.
What bedding fits the small double Silentnight Comfort Pocket Essentials?
You'll need small double (4ft) fitted sheets, since standard double sheets will bag loosely at the corners. A standard double duvet works well on top and gives a generous overhang on both sides. Because 4ft is a standard UK size, bedding is easy to find on the high street, though the range is slightly narrower than for a UK double.
