Layer Details
- Sleep Surface. A naturally hypoallergenic fabric that sits directly against your bedding. It's soft and gentle on the skin, a small comfort if you have sensitive skin or allergies.
- Comfort Breathe®. Silentnight describes these fibres as 15x more breathable than standard memory foam, promoting airflow and regulating temperature. In practice, that means less of the heat build-up hot sleepers dread.
- 2000 Mirapocket Springs. Each of the 2000 springs sits in its own pocket and responds independently to your movements. That gives zoned support and better spinal alignment, and it also limits how much you feel a partner moving.
- Protective Layer. This layer disperses pressure from the spring unit across the mattress. The idea is a longer working life, as no single area takes all the strain.
- Durable Case. A soft but durable outer case designed to keep the mattress comfortable for years. It holds everything together rather than adding a distinct feel of its own.
Layer details from silentnight.co.uk product page, September 2026.
- Room to sleep apart, together: The UK king is 15cm wider than the UK double, which means each of you gets a proper strip of bed rather than negotiating the middle.
- Springs that keep movement on one side: The 2000 Mirapocket springs respond independently, so on a bed this wide an early alarm on one side is far less likely to wake the other.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a genuine relief if either of you is approaching six foot.
- Cooler across a bigger surface: The Comfort Breathe layer is designed to promote airflow rather than trap warmth, and with 75cm each you can shift to a cooler patch of bed.
- Fits most main bedrooms: We suggest allowing at least 2.7m x 2.9m, which most UK master bedrooms can manage once wardrobes and bedside tables are accounted for.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you gets up hours before the other and you want the pocket springs and extra width working together to keep the peace. It also suits you if either sleeper is tall, since the 200cm length gives feet somewhere to go, or if a dog has quietly claimed a corner of the bed most nights.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone. We'd recommend the UK double instead, which needs a smaller footprint: allow at least 2.6m x 2.8m for that size.

Is a UK king big enough for a couple on a medium soft mattress?
Yes, comfortably for most. The UK king gives 75cm each for two people sharing, and because the Eco Comfort Breathe 2000 sits medium soft, that width stops you sinking towards each other in the middle. Heavier couples who want more separation could consider the UK super king, which is 30cm wider than the UK king.
Will the UK king reduce disturbance if my partner gets up earlier than me?
It helps on two fronts. The 2000 pocket springs move independently, so their side compresses without dragging yours down, and the 150cm width means they can slip out from their own edge of the bed. Neither fully silences a restless sleeper, but the combination makes early starts noticeably easier to sleep through.
What room size do I need for the Silentnight Eco Comfort Breathe 2000 in a UK king?
We suggest allowing at least 2.7m x 2.9m, with more feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they look on a floor plan, so measure the usable floor space rather than the room's stated dimensions before committing to a UK king.
Is the UK king long enough for someone over six foot?
At 200cm, or 6ft 6in, it gives a sleeper around six foot roughly a pillow's depth of clearance, which is enough for most. The UK king is 10cm longer than the UK double, so if length is your complaint with your current bed, this size solves it. The UK super king is the same length, so sizing up only adds width.
