Layer Details
- Intense™ sleep surface. The top layer uses scientifically proven Intense™ fabric technology woven into the sleep surface itself. It's Oeko-tex® approved and free from FR chemical treatments, which means fewer chemical finishes next to your skin.
- Latex and EcoMemory Fibre™. Beneath the surface sits a blend of latex and EcoMemory Fibre™. This is the comfort layer, cushioning your pressure points and helping to reduce sleep disturbance if you share the bed.
- Mirapocket® springs. At the core are 2000 Mirapocket® springs that adjust to your movements throughout the night. The zoned support is scientifically proven to improve spinal alignment and posture, so heavier areas like your hips get firmer resistance.
Layer details from silentnight.co.uk product page, September 2026.
- Space to be undisturbed: With 90cm each for two people sharing, most movement from the other side of the bed simply happens too far away to wake you.
- Motion damping meets distance: The latex and EcoMemory Fibre™ comfort layer already reduces sleep disturbance, and at this width the springs your partner is on are barely the ones you're on.
- Room for visitors: If children or a large dog find their way in most nights, a 6ft width means everyone keeps a workable share rather than someone clinging to the edge.
- Full 2000-spring spread: The zoned Mirapocket® springs cover the whole 180 x 200cm surface, so each sleeper gets proper alignment support even sleeping well apart.
- Extra length as standard: At 200cm long, 10cm more than a UK double, taller sleepers get a gentle medium-soft surface without their feet hanging off the end.
This size suits you if...
You share the bed every night and want the maximum standard UK size, your sleep gets broken by a restless partner and distance matters more than any comfort layer, or your household routinely includes a wandering child or a large dog and a UK king still feels crowded. It also suits a larger master bedroom where a smaller mattress would look lost.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m minimum, or the mattress mostly sleeps one person. This model skips the UK king entirely, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m for that size.

How big is the Silentnight Lift Replenish in a super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That works out at 90cm each for two people sharing, and at 30.5cm deep it's a substantial mattress, so make sure your bed frame is rated for a UK super king before ordering.
Does the Silentnight Lift Replenish 2000 come in a UK king?
No. This mattress is made in UK single, UK double and UK super king only. If a UK king was your first choice, the UK super king is 30cm wider and the same length, so sizing up is often the easier move if your room allows it.
What room size suits the Silentnight Lift Replenish super king?
We suggest at least 3m x 2.9m, with more feeling comfortable once you add bedside tables and walking space on both sides. In a loft conversion, check the ceiling slope too, as a 180cm wide bed limits which wall it can sit against.
Is the super king worth it for a restless partner?
It's the strongest case for this size. The latex and EcoMemory Fibre™ layer softens movement, but 90cm of width each does most of the work: turns and duvet tugs happen far enough away that a medium-soft surface stays calm on your side.
Can I get the super king in a firmer feel?
Yes, Silentnight lists this mattress in medium-soft and medium-firm versions. This page covers the medium-soft, which suits side sleepers and lighter builds. Heavier builds or front sleepers wanting the same 180 x 200cm footprint should check the listing carefully to order the medium-firm instead.
