Layer Details
Comfort layer
Eco Comfort Fibre fillings sit on top of the springs. This is a simple fibre layer rather than foam, so expect a firm, fairly traditional surface rather than a deep, hugging one.
Spring system
A Miracoil open coil system with no roll-together and reinforced edges for more sleeping area. It gives you a firm, supportive base, and the stronger edges mean you can use more of the bed's width.

Key benefits
- Firm support that suits sharing: The Miracoil zoned springs resist body weight where it concentrates, which means each of you gets steady support without hollowing out the middle of the bed.
- A footprint most rooms can take: At 135 x 190cm, it leaves space for wardrobes and drawers where a UK king would crowd the room; we suggest allowing at least 2.6m x 2.8m.
- Room for bedside tables on both sides: In a typical UK bedroom the UK double usually leaves enough wall either side for a table and lamp each, which a wider size often sacrifices.
- Easy to dress cheaply: Double sheets and a 200 x 200cm double duvet are stocked everywhere at every price, useful if you're kitting out a whole home at once.
- A sensible pick for a guest room: The firm feel suits occasional use by visiting couples, and the size fits a spare room alongside the furniture that usually lives there.
This size suits you if...
You share the bed every night and prefer sleeping fairly close, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also fits if your bedroom is around the typical UK size, where you want two bedside tables and a wardrobe to fit comfortably alongside the bed, or you're furnishing a spare room for visiting couples.
Consider another size if...
You and your partner both like room to stretch, or one of you sleeps restlessly; 67.5cm each for two people sharing can feel snug. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m of room space.

FAQ's
Is a UK double big enough for a couple on a firm mattress?
For most couples, yes, with a caveat. The UK double gives 67.5cm each for two people sharing, and because the Special Sleep is firm you won't roll towards each other the way you might on a softer bed. If either of you is broad shouldered or spreads out in the night, the UK king is the safer choice.
Will the Silentnight Special Sleep double fit in a small bedroom?
In most cases. We suggest allowing at least 2.6m x 2.8m for a UK double, which leaves room to walk round the bed and open drawers. In a compact second bedroom or first flat, measure with the wardrobe and chest of drawers marked out before you commit.
Should I get the Special Sleep in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king, so the decision is really about your room and your sleeping style. If you have at least 2.7m x 2.9m and either of you is tall or restless, size up. If space is tighter, the UK double is the sensible compromise.
Is the double a good size for a solo sleeper?
Yes, arguably the most comfortable option for one. You get the full 135cm width to yourself, which is plenty to stretch out, share with a pet, or change position freely on the firm Miracoil surface. It costs less to dress than a UK king and fits rooms a larger bed wouldn't.
Can a double mattress get up narrow stairs in an older house?
Usually, though it takes more care than a UK single. At 4ft 6in x 6ft 3in, a UK double will turn most staircases when tilted, but sprung mattresses like this one don't bend the way rolled foam does. Measure any tight turns or low landings before delivery day.
