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.

- Fits where a bigger bed can't: At 90cm wide it slots under a loft slope or between a wardrobe and a desk, and we suggest a room of just 2.1m x 2.8m.
- Grows with a child or teen: The choice of medium soft or medium firm means you can match the feel to a lighter child now or a heavier teenager later.
- Full spring count, small footprint: You still get all 2,000 Mirapocket® springs in the UK single, so a solo sleeper is supported edge to edge rather than getting a cut-down build.
- Latex that suits restless sleepers: The latex and EcoMemory Fibre™ layer responds as you move, which means a fidgety child or a guest in a spare room settles more easily.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child's room or a teenager's first proper mattress, you need a bed for a spare room that doubles as an office, or you're a single adult in a compact bedroom or first flat where a 90cm width is the sensible ceiling. It also suits a bunk or mid-sleeper frame, provided the frame's depth allowance works, since UK singles are the standard fit for those.
Consider another size if...
You share the bed, or you're an adult who feels hemmed in at 90cm wide. The UK single is 45cm narrower than the UK double, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m of floor space for it.

What are the dimensions of the Silentnight Lift Replenish 2000 in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It's the standard one-person mattress size in the UK, and we suggest allowing a room of at least 2.1m x 2.8m so there's space to move around the bed comfortably.
Will the Silentnight Lift Replenish 2000 single fit a bunk bed or mid sleeper?
The UK single is the standard size for bunk and mid-sleeper frames, so the footprint fits. The one thing to check is depth: at 30.5cm this is a tall mattress, and on a top bunk it may sit too high against the guard rail. Measure your frame's maximum mattress depth before ordering.
Is a UK single big enough for an adult?
For one adult sleeping alone, yes. At 90cm wide it's the established solo size, and lighter sleepers can pick the medium soft version for a little more give at the hips and shoulders. If you like to sprawl, the UK small double is 30cm wider and the same length.
Which firmness of the Silentnight Lift Replenish 2000 should I pick for a child's single?
Silentnight offers this mattress in medium soft or medium firm. Lighter children and dedicated side sleepers will usually get better pressure relief from medium soft, while a heavier teenager, or a back or front sleeper, is likely to feel better held on medium firm.
How much bigger is a UK double than a UK single?
The UK single is 45cm narrower than the UK double, and the two sizes are the same length. If you're weighing up the step, the UK double needs a room of at least 2.6m x 2.9m less floor space isn't the point here: we suggest at least 2.6m x 2.8m for the UK double, against 2.1m x 2.8m for the UK single.
