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 narrow footprint for compact rooms: At 90cm wide it leaves floor space free in a small bedroom, so a wardrobe, desk and toy storage can still fit around it.
- Medium-soft suits lighter sleepers: Children, teens and lighter adults tend to get on well with a medium-soft feel, which cushions rather than pushes back.
- 2000 Mirapocket® springs in a single: The zoned springs adjust to your movements through the night, giving firmer resistance under your hips while your shoulders sink in a little.
- A gentler surface next to young skin: The Intense™ sleep surface is Oeko-tex® approved and free from FR chemical treatments, a reassurance for a child's bed.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and both are among the most widely stocked bedding sizes in the UK.
This size suits you if...
You're buying for a child's or teenager's room where the bed shares floor space with a desk and storage, you're a lighter adult sleeping solo who wants a gentler medium-soft feel, or you're furnishing a spare room that doubles as an office and only a 90cm-wide bed will leave you space to work.
Consider another size if...
You share the bed, or you're a taller solo sleeper who finds 190cm restrictive. We'd recommend the UK double instead: it's 45cm wider than the UK single, the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

FAQ's
What size is the Silentnight Lift Replenish 2000 single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any standard single bed frame and takes standard single bedding without any hunting around for unusual sizes.
How much room do I need for the Silentnight Lift Replenish single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you a walkway alongside the bed and room to open drawers or a wardrobe. In a loft conversion, the narrow 90cm footprint also makes it easier to place the bed away from the slope.
Is the Silentnight Lift Replenish 2000 single suitable for a bunk or mid sleeper?
Check your frame first. This mattress is 30.5cm deep, and many bunk and mid-sleeper frames set a maximum mattress depth so the safety rail still sits high enough above the sleeping surface. If your frame's limit is below 30.5cm, a shallower mattress would be the safer choice.
Is the medium-soft single a good choice for a child or teenager?
Generally yes. Lighter builds don't sink far into a mattress, so a medium-soft feel gives them cushioning a firmer surface wouldn't. The Oeko-tex® approved surface, free from FR chemical treatments, is an added reassurance. A heavier teen who sleeps on their front may prefer the medium-firm version of the same mattress.
Does standard single bedding fit this mattress?
Yes. At 90 x 190cm it takes standard UK single fitted sheets and a single duvet, which is 135 x 200cm. One thing to check: at 30.5cm deep it's a tall mattress, so look for fitted sheets with a deep enough pocket, ideally listed as extra deep.
