Layer Details
Plush pillow top
A plush layer stitched onto the surface of the mattress for extra comfort and support. It softens the feel of the top without changing the firm rating.
Mirapocket spring core
1000 Mirapocket springs, each in its own fabric pocket and reacting independently. That means the mattress follows your movements and helps limit disturbance to a partner.
Protective base layer
A layer under the springs that spreads their pressure across the whole surface. It's there to help the mattress last longer.
Layer details from mattressman.co.uk product page, October 2026.
Key benefits
- 90cm each for two sharing: Each sleeper gets 90cm of width, which means a restless partner's shifting happens noticeably further away from you than on smaller sizes.
- 15cm more each than a UK king: Sizing up from the UK king adds 15cm per person at the same length, enough that a late-night visitor no longer leaves an adult clinging to the edge.
- Springs that react separately: The 1000 Mirapocket springs each move on their own, so a child or dog climbing in on one side is less likely to wake the other sleeper.
- Firm support across a big surface: The firm rating keeps the surface supportive under a family pile-in, while the stitched pillow top takes a little of the edge off where you lie.
- Fits a large master bedroom: In a period property or a big new master bedroom, a UK super king fills the space properly where a UK king can look slightly lost.
This size suits you if...
You share with a partner whose tossing and turning keeps waking you, or the bed regularly gains a child or a large dog by morning, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room falls short of 3m x 2.9m, or a tight landing makes a 180cm-wide mattress risky. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m.

FAQ's
Is a super king Silentnight 1000 Pillow Top worth it over a double for two adults?
If you both sleep restlessly, it's a big step up. The UK double gives 67.5cm each for two sharing, while the UK super king gives 90cm each, so you gain 22.5cm per person and 10cm of length. Measure your room first, then compare the retailers listed on this page for the UK super king.
How big does my bedroom need to be for a super king Silentnight 1000 Pillow Top?
We suggest at least 3m x 2.9m for a UK super king, although around 3.5m x 3.2m feels more comfortable once you add bedside tables and space to walk round. In a loft conversion, check where the ceiling slopes before choosing a wall, because the bed needs headroom on both sides.
Is a super king better than a king for a restless partner on this mattress?
Usually, yes. The UK king gives 75cm each for two sharing, while the UK super king gives 90cm each, so you gain 15cm of distance per person. The individually pocketed springs reduce movement transfer, but extra width does more than any comfort layer when a partner moves a lot.
Can children and a dog share a firm pocket sprung super king comfortably?
The width helps most here: with 90cm each, a child tucked in the middle or a large dog at the foot doesn't push either adult out. The firm rating keeps the surface supportive under extra bodies, though lighter children may find it a little unforgiving on its own.
What bedding do I need for a Silentnight super king mattress?
You'll need UK super king sheets and a 260 x 220cm duvet. At 27cm deep, this mattress needs a fitted sheet with a deep enough pocket to grip the corners properly, so check the sheet depth before buying, as super king bedding is a bigger outlay than smaller sizes.
