Layer Details
- Intense™ sleep surface. The sleep surface is woven with Silentnight's Intense fabric technology, approved by Oeko-tex and free from FR chemical treatments. That means fewer chemicals between you and the mattress, a small but genuine reassurance.
- Luxurious Latex. A latex comfort layer that moves when you do, giving cushioning and pressure relief with even weight distribution. In practice this means freedom of movement: you won't sink in and stay put.
- 1200 Mirapocket® springs. 1200 individual pocket springs adjust to your body weight, with zoned support that Silentnight states is scientifically proven to improve spinal alignment and posture. Each spring works independently, so a restless partner is less likely to disturb you.
Layer details from silentnight.co.uk product page, September 2026.
- 90cm each, every night: Two sharers each get 90cm of width, which means a partner turning over happens at a distance rather than against your back.
- Space that backs up the springs: The 1200 individual Mirapocket springs already limit motion transfer, and the extra width means most movement never reaches your side at all.
- Room for night-time visitors: A child wandering in at 3am, or a dog who treats the bed as home, still leaves both adults a usable share.
- Latex freedom across a bigger surface: The latex layer responds quickly when you move, so restless sleepers can shift around freely without waking anyone across all that width.
- Fills a large master properly: In a big period bedroom or new build master, a smaller bed can look lost; at 6ft x 6ft 6in this one holds the room.
This size suits you if...
You share every night and want movement on the other side of the bed to stop registering, your children or pets join you often enough that a UK king feels crowded, or you have a large master bedroom where a smaller mattress would look undersized. Allow at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling comfortable.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or you'd struggle to get a mattress this size round your landing. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is the Silentnight Lift Renew 1200 super king good for a restless partner?
It's arguably the best size of this mattress for exactly that. The 1200 pocket springs move independently, so one sleeper's tossing transfers less to the other, and with 90cm of width each most movement happens too far away to notice. Distance does a lot of the work that no comfort layer can.
How much bigger is the super king Lift Renew 1200 than the UK king?
The UK super king is 30cm wider than the UK king, and the two are the same length. That extra width is the whole argument for sizing up: it turns a comfortable bed for two into one where a third small occupant doesn't cost anyone their space.
Will the Silentnight Lift Renew 1200 super king fit my bedroom?
The mattress is 180 x 200cm, and we suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling right if you want bedside tables on both sides and a clear walkway. Measure door swing and any landing turns too; at this size the route to the room matters as much as the room.
Is the super king big enough for two adults and a child?
Realistically, yes. With 90cm per sleeper for two adults, there's slack in the layout when a child climbs in during the night. The zoned pocket springs adjust to each person's body weight independently, so a lighter occupant doesn't unbalance the support for the adults either side.
Where can I buy the Silentnight Lift Renew 1200 in a UK super king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so it's the most reliable place to check. One naming quirk to watch for: Silentnight's own site calls this mattress the Lift Renew Hybrid 1200, but it's the same product.
