Layer Details
ActiveBreathe layer
This comfort layer feels like memory foam but is ten times more breathable, which means contouring comfort without the overheating foam is known for. If you tend to sleep warm, this is the feature to pay attention to.
Mirapocket® spring system
Silentnight's Mirapocket® system uses 800 pocket springs in the king size. Each spring moves independently, so the mattress responds to your shape and reduces the ripple effect when a partner shifts position.
Eternity layer
The base Eternity layer gives the mattress extra stability and long lasting resilience. In practice, that means the firm feel should hold up rather than softening quickly.

Key benefits
- A footprint most bedrooms can take: At 135 x 190cm (4ft 6in x 6ft 3in), the UK double leaves room for wardrobes and drawers where a UK king would dominate.
- Independent springs matter more when sharing: The Mirapocket® springs move individually, which means a partner turning over on their half of the double is less likely to wake you.
- Cooler for two: Two people warm a shared 135cm surface quickly, so the ActiveBreathe layer's memory foam feel without the trapped heat is a real advantage here.
- Firm support across the width: The Eternity base layer adds stability, which means the firm feel should hold up on both sides rather than dipping where each of you sleeps.
- Easy to dress: Double sheets and a 200 x 200cm double duvet are stocked everywhere at every price, handy if you're kitting out a bedroom on a spread budget.
This size suits you if...
You share the bed every night and your bedroom is a typical UK size, where a UK king would leave you squeezing past the footboard. It also suits you if you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner, or you're furnishing a guest room that needs to take visiting couples without swallowing the whole floor.
Consider another size if...
You and your partner both like space and your room measures well beyond the minimum. The UK double is 15cm narrower and 10cm shorter than the UK king, so we'd recommend the UK king instead; allow at least 2.7m x 2.9m for it.

FAQ's
What are the dimensions of the Silentnight Revitalise Refresh 800 in a UK double?
The UK double measures 135 x 190cm, or 4ft 6in x 6ft 3in. It's the same length as the UK single and UK small double, while the UK king is 15cm wider and 10cm longer. Check your bed frame is a standard UK double before ordering, as EU doubles differ.
Is the Silentnight Revitalise Refresh 800 UK double big enough for a couple?
For most couples, yes. You get 67.5cm each for two people sharing, and the Mirapocket® springs respond to each of you independently, so movement on one side carries less to the other. Larger sleepers, or anyone who sprawls, may find the width a little tight and prefer the UK king.
What room size do I need for the Silentnight Revitalise Refresh 800 UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance rather than Silentnight's, and it assumes you want bedside tables on both sides and space to open drawers. In a first flat or second bedroom, the double usually fits where a king wouldn't.
Does the UK double suit a solo sleeper on this mattress?
It does, and generously. All 135cm is yours, which is 45cm more than the UK single at the same length, so there's room to spread out or share with a pet who has claimed a corner. The firm feel gives consistent support wherever on the surface you settle.
When should I pick the UK king over the UK double for this mattress?
Size up if your room comfortably exceeds 2.7m x 2.9m, our suggested minimum for the UK king, and you both value space over floor room. The UK king is 15cm wider and 10cm longer, useful for taller sleepers. Otherwise the UK double keeps the same firm hybrid feel in a friendlier footprint.
