Layer Details
Intense™ sleep surface
A sleep surface woven with Silentnight's scientifically proven Intense™ fabric technology, approved by Oeko-tex® and free from FR chemical treatments. In practice, that means the layer closest to your skin has been checked for harmful substances.
Latex and EcoMemory Fibre™
A blend of latex and EcoMemory Fibre™ designed to reduce sleep disturbance and add cushioning comfort. The latex moves when you do, which means your weight stays evenly distributed and pressure points get relief as you shift through the night.
Mirapocket® springs
2,000 Mirapocket® springs that adjust to your movements throughout the night for tailored support. The zoned design is scientifically proven, per Silentnight, to improve spinal alignment and posture.
Layer details from silentnight.co.uk product page, September 2026.
Key benefits
- 90cm each for two sharers: With 90cm each for two people sharing, a restless partner is simply further away, which does more for undisturbed sleep than any comfort layer can.
- Latex that absorbs movement: The latex and EcoMemory Fibre™ blend is designed to reduce sleep disturbance, and at this width the two things work together: cushioning plus distance.
- 2,000 springs across the full width: The zoned Mirapocket® springs adjust to movement across the whole 180cm, so support stays consistent even when someone drifts over to your side.
- Room for the whole household: If children or a large dog treat your bed as theirs, this is the size where everyone still gets a share without anyone clinging to an edge.
- A choice of feel for two different sleepers: The medium soft or medium firm options let a couple pick the feel that suits them both before committing to a mattress this large.
This size suits you if...
You share the bed every night and one of you moves around enough to wake the other, or children and pets regularly join you and a UK king no longer stretches to everyone. It also makes sense if you have a large master bedroom, perhaps in a period property or a new build with a generous main room, where a smaller bed would look and feel undersized.
Consider another size if...
Your bedroom is under the 3m x 2.9m we suggest as a minimum for this size, or you sleep alone. We'd recommend the UK super king's nearest sibling, the UK king, instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on the Silentnight Lift Replenish 2000 super king?
Two people sharing get 90cm each, the widest per-person share of any standard UK size. In practice that means a partner who turns over frequently, or a child who wanders in during the night, is far enough away that the latex layer's motion-reducing design rarely gets tested.
What size room do I need for this mattress in a super king?
We suggest at least 3m x 2.9m for a UK super king, and that's our guidance rather than Silentnight's. Measure with door swing and wardrobe access in mind, because at 180 x 200cm this mattress dominates a room. If your floor plan won't stretch that far, the UK king needs slightly less: we suggest at least 2.7m x 2.9m.
Is the super king longer than the king in this mattress?
No. The UK super king and the UK king are the same length; the difference is width, with the UK super king 30cm wider. So if you're upgrading from a UK king for space reasons, you're buying elbow room rather than legroom, and your bed's position along the wall won't need to change.
Is a super king big enough to share with children or pets?
This is the size we'd point you to for that. With 90cm each for two adults, a child or a large dog joining overnight takes a share without pushing anyone to the edge, and the 2,000 zoned Mirapocket® springs keep support consistent wherever everyone ends up lying.
Where can I buy the Silentnight Lift Replenish 2000 in a super king?
Stock varies by size, so the best answer is the live retailer table on this page, which is updated as retailers change their prices and availability. Because this mattress is made to order, delivery takes around 14 days whichever retailer you buy the UK super king from.
