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.

Key benefits
- A shared bed that fits the room: At 135cm wide, the UK double leaves space to walk round the bed in rooms where a UK king would crowd everything else out.
- 67.5cm each for two sharing: Two people get 67.5cm each, which works comfortably here because the 2000 Mirapocket® springs respond to each sleeper's movements separately.
- Less disturbance at close quarters: Sharing a double puts you nearer your partner, so the latex and EcoMemory Fibre™ comfort layer's ability to soften movement across the surface counts for more.
- Works for solo sleepers too: Sleeping alone, the full 135cm width gives you generous room to spread out, even with a dog or cat claiming a corner.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, at every price point.
This size suits you if...
You share the bed every night and your room suits a double better than a UK king, you want bedside tables on both sides without squeezing past furniture, or you sleep alone and want space to stretch out. The medium-soft feel favours side sleepers and lighter builds, so it works best for couples who both prefer a gentler, more cushioned surface.
Consider another size if...
Your room is under our suggested minimum of 2.6m x 2.8m, or you both want noticeably more personal space. For the latter, we'd recommend the UK super king, which is 45cm wider and 10cm longer; allow at least 3m x 2.9m for it.

FAQ's
Is a UK double big enough for two on the Silentnight Lift Replenish 2000?
Yes, for most couples. You each get 67.5cm of width, and the 2000 Mirapocket® springs adjust to each of you independently, so one person's movements are less likely to travel across the bed. Broader builds, or couples who like to sprawl, may prefer the extra 45cm of width the UK super king offers.
What room size do I need for the Silentnight Lift Replenish in a UK double?
We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows the mattress's 135 x 190cm footprint plus room to walk down both sides and, in most layouts, bedside tables each side. If your room is tighter than that, the UK single fits in rooms from 2.1m x 2.8m.
Should I get this mattress in a UK double or a UK super king?
The UK double is 45cm narrower and 10cm shorter than the UK super king, so the choice comes down to your room. In a typical UK bedroom the double leaves space for other furniture; the super king needs at least 3m x 2.9m by our guidance. If you have the space and share every night, the extra width is a genuine comfort gain.
Is the UK double a good choice for a guest room?
It's the natural pick if visiting couples will use the room. A double fits alongside a wardrobe and drawers in most spare rooms, and the medium-soft feel is forgiving for occasional guests of different builds, though heavier front sleepers may find it a little too yielding for every night.
Will a double Silentnight Lift Replenish fit up a narrow staircase?
At 135 x 190cm and 30.5cm deep, it's a substantial mattress, so measure any turning stairs or tight landings before ordering, particularly in older terraces and some new builds. Silentnight doesn't publish delivery access guidance for this size on the details we have, so check with the retailer you order from before delivery day.
