Layer Details
Intense sleep surface
The top of the mattress has Intense fabric technology woven into it, which Silentnight says helps the body relax for deeper, undisturbed sleep. It is the part you lie on first, so it sets the tone for how the mattress feels.
Latex and EcoMemory Fibre comfort layer
This layer pairs latex for cushioning with EcoMemory Fibre, which moves with you to relieve pressure. For a soft feel, that means a surface that gives way gently at the shoulders and hips.
Mirapocket pocket springs
The base has 2000 Mirapocket springs that adjust to movement and offer zoned support. They give the mattress its structure, so the soft top layers are backed by support that varies across your body.

Key benefits
- Real space for two: At 75cm each for two people sharing, you both get room to settle into the soft surface without meeting in the middle.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, which means anyone approaching six foot stops sleeping diagonally.
- Less partner disturbance: The pocket springs in this hybrid respond individually, and the wider footprint of a UK king puts more distance between you when one of you leaves early.
- Soft feel across a bigger surface: Side sleepers get the pressure relief at shoulder and hip this softer variant is built for, with space to change position freely.
- Room for a stowaway: If the dog treats the bed as its own, the UK king absorbs that habit far better than a double does.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially on a soft surface where you sink in rather than skate over it. Or one of you is on a different schedule, up hours before the other, and you want enough width that the early riser can slip out without a ripple reaching the far side. Taller sleepers get the 200cm length too.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, allowing at least 2.6m x 2.8m for it.

FAQ's
Is a UK king big enough for a couple on a soft mattress?
Yes, comfortably for most couples. Two people sharing get 75cm each, and the soft feel of this Lift Replenish variant means you nestle into your own patch of the surface rather than drifting towards your partner. The 2000 pocket springs also limit motion transfer, so movement on one side is less likely to wake the other.
What room size do I need for the Silentnight Lift Replenish in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure with the furniture in place. If your room is under our minimum, the UK double needs at least 2.6m x 2.8m.
How much bigger is the UK king than the double for this mattress?
The UK king is 15cm wider and 10cm longer than the UK double. The width is what couples notice night to night, but the length is the quieter win: at 5ft x 6ft 6in, it stops taller sleepers' feet hanging off the end, which a 190cm double never quite solves.
Should a taller sleeper size up to the UK super king instead?
Not for length: the UK king and the UK super king are the same length at 200cm, so sizing up buys width alone. The UK super king is 30cm wider, but we suggest at least 3m x 2.9m of room for it. If height is your reason for upgrading, the UK king already delivers it.
