Miracoil zoned spring system
- Proper space for two: At 75cm each for two people sharing, you can both change position freely, which means fewer elbows and less negotiating over the middle.
- Less disturbance on different schedules: The Miracoil zoned springs are designed for even weight distribution, so an early riser slipping out is less likely to wake the person still sleeping.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, a genuine relief if either of you is approaching six foot.
- Firm support across the full width: The firm feel stays consistent edge to edge, so neither of you rolls towards the centre even with the extra room.
- An affordable route to a bigger bed: Sizing up usually stings, but this sits at the affordable end of Silentnight's range, so the jump to a UK king is gentler on the budget.
This size suits you if...
You share the bed every night and a double now feels cramped, especially if one of you leaves for work hours before the other and wants to slip out without a fuss. It also fits if either of you is tall enough to need the 200cm length, or you're expecting a baby and want room for pillows and constant repositioning without crowding your partner out.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, which is common in new builds once wardrobes go in. We'd recommend the UK double instead, where we suggest at least 2.6m x 2.8m.

Is the Silentnight Comfort Miracoil Essentials UK king big enough for a tall sleeper?
Yes, and length is the quiet win here. The UK king is 200cm long, 10cm more than the UK double, which stops taller sleepers' feet hanging off the end. Combined with the firm Miracoil support, someone approaching six foot gets full-length support rather than making do.
Will a UK king fit in a new build master bedroom?
Often, but measure first. The mattress is 150 x 200cm, and we suggest a room of at least 2.7m x 2.9m so you can still open wardrobes and walk round both sides. Many new build masters look generous empty but shrink fast once fitted furniture goes in.
How much space does each person get on this mattress in a UK king?
You get 75cm each for two people sharing, which is enough to sleep with arms out rather than pinned to your side. On a firm mattress like this one, that width also means you can shift position through the night without nudging your partner awake.
Does the king size help if my partner and I keep different hours?
It helps more than most upgrades. The Miracoil zoned spring system spreads weight evenly, so movement transfers less across the bed, and the 150cm width puts real distance between you. One of you getting up at 5am is far less disruptive than it would be on a narrower mattress.
