Layer Details
- UltraGel comfort layer. A gel infused foam layer that adjusts to your body's movements while helping to cool you down, which means pressure relief without the heat build-up plain foam can cause. It also has a degree of bounce back, so you shouldn't feel stuck in one position.
- Mirapocket springs. 2,000 pocket springs that move independently of one another, giving zoned support where your body needs it. Because each spring reacts on its own, movement on one side of the bed is far less likely to disturb the other.
Layer details from silentnight.co.uk product page, September 2026.
- 90cm of space each: Two people sharing get 90cm each, which means you can spread out fully without ever brushing against your partner.
- Distance plus independent springs: The 2,000 Mirapocket springs already limit motion transfer, and the extra width means most movement happens too far away to reach you anyway.
- Room for night-time visitors: If children wander in during the small hours, or a large dog treats the bed as home, there's enough width for everyone to keep a fair share.
- 30cm wider than a UK king: The UK super king is 30cm wider than the UK king and the same length, a noticeable difference for couples who found a king a little snug.
- Cooling across a bigger surface: The gel infused comfort layer draws heat away, useful at this size where more bodies under one duvet can mean a warmer bed.
- Fills a larger master properly: In a big period bedroom or a generous new build master, a smaller mattress can look lost, while this size sits in proportion.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your sleep is regularly interrupted by a partner who turns over a lot, or your household routinely includes children or pets in the bed and you'd rather plan for that than fight it. Your room should measure at least 3m x 2.9m by our guidance.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you'd struggle to get a mattress this wide up your stairs. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is the Silentnight UltraGel 2000 super king good for restless partners?
Yes, arguably more than any smaller size. The 2,000 pocket springs move independently, so one sleeper's tossing transfers less through the mattress, and with 90cm each for two people sharing, most movement is simply too far away to feel. If disturbed sleep is your main complaint, the width does as much work as the springs.
What room size do I need for the Silentnight UltraGel 2000 in a UK super king?
We suggest a room of at least 3m x 2.9m for a UK super king. That's our own guidance rather than Silentnight's, and it allows for walking space and bedside tables on both sides. In a tighter room the bed will dominate, and opening drawers or the door can become a daily annoyance.
Should I choose the UltraGel 2000 in a UK king or a UK super king?
The UK super king is 30cm wider than the UK king, and the two are the same length. If you share with children or pets, or a partner who moves a lot, that extra width earns the bigger room requirement. If your room can only meet the 2.7m x 2.9m we suggest for the UK king, take the UK king.
How much space does each person get on a super king UltraGel 2000?
90cm each for two people sharing. That's a full single bed's worth of width per person, so you can both sleep in any position without negotiating territory. Given this mattress has a medium soft feel with plenty of give, having room to spread out means neither of you drifts into the other's dip.
Is the super king size worth it for a family who share the bed?
If children regularly appear at 3am, or a large dog considers the bed theirs, the UK super king is the size that absorbs it. At 180cm wide, an extra small body doesn't leave the adults clinging to the edges, and the independent springs mean a wriggling child disturbs the mattress less than you'd expect.
