Layer Details
- ActiveBreathe layer. This comfort layer feels like memory foam but is ten times more breathable, which means you get pressure relief without the heat build-up. It also allows ease of movement, so you shouldn't feel stuck in one position overnight.
- Mirapocket® spring system. Silentnight's pocket spring system, with 1400 springs in the king size, provides zoned support. In practice that means even weight distribution and improved spinal alignment, aimed at reducing aches and pains.
- Eternity layer. A base layer that gives the mattress extra stability and long lasting resilience. It's there to help the mattress hold its shape over years of use.
Layer details from furniturevillage.co.uk product page, September 2026.
- 90cm of space each: Two people sharing get 90cm each, which means a restless partner can turn all night without you feeling much of it.
- Room for the household: When a child pads through at 3am or a large dog treats the bed as home, 180cm of width means nobody ends up clinging to the edge.
- Extra firm across the full width: The Mirapocket® spring system gives zoned support edge to edge, so the sleeper who migrates across all that space gets the same push-back everywhere.
- Firm surface, cooler feel: The ActiveBreathe comfort layer offers pressure relief without foam's trapped heat, useful when two adults and occasional visitors are warming one mattress.
- A long guarantee for a big purchase: Furniture Village lists a 20-year structural guarantee, reassuring on a mattress this size that you'll want to keep for years.
This size suits you if...
You share the bed every night and one of you is a light sleeper or a fidgeter, so distance matters as much as feel. You want a genuinely firm surface and a room that can take it, ideally 3m x 2.9m or more. Or your bed is a family gathering point, with children or pets joining regularly, and a UK king has started to feel crowded.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or the super king would dominate the space. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

How big is the Silentnight Revitalise Ortho 1400 in a UK super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That's 30cm wider than the UK king and 45cm wider than the UK double, at the same 200cm length as the UK king. For two people sharing, it works out at 90cm of width each, the most of any standard UK size.
Is a super king worth it for a restless partner?
Often, yes. No comfort layer can fully hide a partner who turns all night, but 90cm of space each means their movement happens further away from you. On an extra firm mattress like this, where there's little sink to cushion motion, that extra distance does more for undisturbed sleep than any upgrade in materials would.
Will the super king Revitalise Ortho 1400 fit in my bedroom?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. Check more than floor space, though: door swing, the turn on your landing and stair width all bite at this size. Measure the tightest point of the route to the bedroom before ordering.
Should I choose the super king or the UK king in this mattress?
If your bed is shared with children or pets, or one of you sleeps restlessly, the super king's extra 30cm of width is the better buy. If your room is tighter, the UK king suits smaller spaces, needing at least 2.7m x 2.9m by our guidance, and both sizes are the same 200cm long.
