Layer Details
- Cover. A knitted, microquilted soft-touch cover, which means a slightly cushioned, cosy surface the moment you lie down. It's designed for enhanced airflow and breathability, so warmth doesn't build up against your skin.
- Comfort Layer. Eco Comfort Fibre fillings that are 100% sustainable and made from recycled materials. They offer cooling and breathability, so you get cushioning without the heat retention some foams can bring.
- Support System. 1000 individual Mirapocket springs, each encased in its own fabric pocket and strengthened by polyester walls. Because each spring responds independently to your body shape, you get pressure relief where you sink and support where you don't.

- Real room to spread out alone: At 30cm wider than the UK single, a solo sleeper can starfish across those Mirapocket springs without an elbow hanging off the edge.
- Fits where a double won't: It's 15cm narrower than the UK double, which can be the difference between a box room door clearing the bed frame and it not.
- Pocket springs at entry-level money: The 1000 individual springs respond to your body shape on their own, a construction you don't always get at this end of the market.
- Breathable fibre comfort layer: Eco Comfort Fibre made from recycled materials lets air move through, useful in a compact room where warmth builds quickly overnight.
- A sensible guest room double: Couples can share 120cm of width for the occasional stay, so it suits a spare room where nobody sleeps every night.
This size suits you if...
You sleep alone and want more width than a single without giving up the floor space a full double demands, your teenager has outgrown their single but the room can't shrink any further, or you're furnishing a guest room where visiting couples stay a few nights a year rather than sharing nightly.
Consider another size if...
You share the bed every night, as 120cm is a squeeze for two adults long term. We'd recommend the UK double instead, which is 15cm wider and needs a room of at least 2.6m x 2.8m.

Is the Silentnight Mirapocket 1000 small double big enough for two adults?
For the odd night, yes. At 120cm wide it gives a visiting couple enough space to sleep comfortably, and the individual pocket springs mean one person turning over disturbs the other less. For every night, though, it's a little tight, and the UK double's extra 15cm of width makes a real difference.
What size room do I need for a small double Mirapocket 1000?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk round the bed and open drawers or a wardrobe without shuffling sideways. The mattress itself is 120 x 190cm, so in a box room or loft conversion it's worth measuring where the door swings before you order.
What are the dimensions of the Silentnight Mirapocket 1000 in a small double?
It measures 120 x 190cm, which is 4ft x 6ft 3in. That's 30cm wider than the UK single but the same length, so a teenager moving up from a single gains width without the bed reaching any further down the room. It's 15cm narrower than the UK double.
Should I get the Mirapocket 1000 in a small double or a double?
It comes down to who sleeps in it and how big the room is. Sleeping solo, the UK small double gives you generous width and keeps 15cm of floor space a UK double would take. Sharing every night, the UK double is the better call, provided your room meets our suggested 2.6m x 2.8m minimum.
Is the small double Mirapocket 1000 a good choice for a teenager?
It's a natural step up from a single: 30cm more width, the same 190cm length, and a medium feel that suits most back and side sleepers. The fibre fillings are hypoallergenic too. Just check the room first, since we'd allow at least 2.4m x 2.8m, and compare the retailers listed on this page for the current price.
