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.
Key benefits
- Proper space for two: At 75cm each for two people sharing, you can both change position freely without negotiating over the middle of the bed.
- Less disturbance on different schedules: If one of you gets up hours before the other, the independently moving pocket springs and the wider surface together make an early alarm far less noticeable.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, so anyone approaching six foot stops sleeping with their feet at the very edge.
- Cooling that suits shared beds: Two bodies generate more heat than one, and the gel infused comfort layer is designed to draw that warmth away rather than trap it.
- A gentler feel at a generous size: The medium soft surface gives side sleepers cushioning across the full 5ft x 6ft 6in footprint, so neither partner is stuck on a firmer edge zone.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you is a side sleeper who wants a softer, more cushioned feel. It also makes sense if either of you is tall, since the extra length over a UK double removes that feet-hanging-off feeling, or if you keep different hours and want movement on one side to stay on that side.
Consider another size if...
Your bedroom can't comfortably take it: we suggest at least 2.7m x 2.9m for a UK king. In a smaller room the UK double would suit you better, and we suggest at least 2.6m x 2.8m for that size.

FAQ's
Is the Silentnight UltraGel 2000 in a UK king good for couples?
Yes, and arguably better than the smaller sizes. You get 75cm each for two people sharing, and the 2,000 pocket springs react individually, so a partner turning over or getting up early is less likely to wake you. Bear in mind the medium soft feel: if either of you prefers a firm surface, this mattress won't suit.
Will a UK king UltraGel 2000 suit a tall sleeper?
The UK king measures 150 x 200cm, which is 10cm longer than the UK double, and that extra length is often the real reason taller sleepers upgrade. If you're approaching six foot, it stops your feet reaching the end of the bed. The width helps too, since taller people tend to take up more of it.
What room size do I need for the UltraGel 2000 in a UK king?
We suggest a room of at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable. Measure with wardrobes and drawers in mind rather than the empty floor plan, as new build master bedrooms in particular can feel tight once the furniture is in. Allow walking space on both sides if you'll each get out on your own side.
Should I get the UK king or the UK super king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length, so the decision is purely about width and room size. We suggest at least 3m x 2.9m for the UK super king. If a dog routinely claims part of the bed, or you both sprawl, the extra width pays off; otherwise the UK king is the more practical fit.
Where can I buy the Silentnight UltraGel 2000 in a UK king?
Several UK retailers stock this size, and coverage does change, so the most reliable approach is to compare the retailers listed on this page. The prices shown here are updated as retailers change them, which means you can check who currently has the UK king at the best price rather than relying on a figure that may already be out of date.
