Layer Details
Microquilted cover
A microquilted cover tops the mattress and gives it an inviting sleep surface. It is the first thing you feel, so it sets the tone for the comfort layers underneath.
Soft white fibres
Two layers of soft white fibres sit below the cover. They add cushioned comfort and extra breathability, so the surface feels softer without trapping as much warmth.
Memory foam
A layer of memory foam moulds around your shape. That gives you contouring where your body presses into the mattress.
Mirapocket springs
The core is 2000 Mirapocket springs, each encased in its own pocket. They form the base of support and respond individually, so the mattress can adapt to your shape.

Key benefits
- Proper space for two: At 75cm each for two people sharing, you can both change position without negotiating, which matters when one of you gets up hours before the other.
- Less partner disturbance: The wider surface puts more distance between you, so an early alarm or a restless night on one side is less likely to wake the other.
- Extra length for taller sleepers: The UK king is 10cm longer than the UK Double, which means feet stay on the mattress rather than hanging off the end.
- Room for the whole household: If the dog treats the bed as its own, a UK king absorbs that habit better than a double ever will.
- A familiar brand at this size: Silentnight is one of the UK's biggest mattress names, and the king is the size most couples upgrading from a double end up choosing.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, one of you keeps different hours and you want space between you to soften the disturbance, or one partner is approaching six foot and needs the 200cm length as much as the width.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum once wardrobes are in, which is common in new build masters. We'd recommend the UK double instead, where we suggest at least 2.6m x 2.8m.

FAQ's
What size is the Silentnight Mirapocket 2000 Memory Mattress in a UK king?
The UK king measures 150 x 200cm, or 5ft x 6ft 6in in imperial. For two people sharing, that works out at 75cm each, noticeably more personal space than a double offers and enough that most couples stop bumping elbows in the night.
What room size do I need for a UK king mattress?
We suggest a room of at least 2.7m x 2.9m for a UK king. That allows walking space around the bed and drawers that still open. Measure with your wardrobes in place rather than from the floor plan, as fitted furniture eats into a room faster than you expect.
Is a UK king long enough for someone over six foot?
Usually, yes. The UK king is 200cm long, 10cm longer than the UK double, and for taller sleepers that length is often the real upgrade rather than the width. If your partner currently sleeps diagonally or with feet over the end, this size tends to fix it.
Should I choose the Mirapocket 2000 in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king, and the two are the same length. Sizing up buys pure width, but we suggest at least 3m x 2.9m of room for the UK super king, so the king is the safer pick in an average bedroom.
