Layer Details
- Gel-infused comfort layer. A gel-infused foam layer that responds as you move, paired with breathable foam. In practice this means a responsive, slightly bouncy feel rather than the slow sink of traditional memory foam.
- Plush pillowtop. A soft pillowtop stitched to the surface for that sink-in feel. This is what gives the mattress its cushioned, medium soft character.
- Mirapocket springs. 1000 Mirapocket springs, each housed in its own fabric pocket so they move independently. Silentnight says the zoned design is scientifically proven to improve spinal alignment and posture, which you'll feel as firmer support where your body is heaviest.
Layer details from silentnight.co.uk product page, September 2026.
- Space to sprawl on a soft surface: A medium soft pillowtop invites you to sink in, and at 120cm wide there's room for a solo sleeper to actually do it.
- A cushioned feel in a compact room: The UK small double is 15cm narrower than the UK double, which can be the difference between a door clearing and a bed frame blocking it.
- 1000 springs under one sleeper: With 1000 Mirapocket springs supporting a single body across 120cm, the zoned support follows your spine rather than compensating for a partner.
- Gel comfort without feeling stuck: The gel-infused foam responds as you shift, so moving across this generous solo width feels easy rather than a slow climb out of a dip.
- Practical for occasional guests: A couple can share it for the odd night, and the plush surface makes a guest room feel more welcoming than a spare-bed compromise.
This size suits you if...
You sleep alone, like a soft, cushioned surface, and have outgrown the width of a UK single, or your bedroom is too tight for a standard double and you'd rather lose 15cm of mattress than the ability to open a drawer. It also fits a guest room or holiday let where couples stay occasionally rather than every night.
Consider another size if...
You share the bed every night, since two adults on 120cm gets snug quickly on a soft pillowtop that lets you settle in place. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room.

Is a small double big enough for the UltraGel 1000 pillowtop feel?
For one person, comfortably. The medium soft pillowtop lets shoulders and hips sink in, and 120cm of width means a solo sleeper can change position freely without reaching the edge. Two adults sharing nightly would feel the squeeze, especially on a soft surface where you tend to settle rather than perch.
Can a couple sleep on the UltraGel 1000 in a UK small double?
For the odd night, yes, which makes it a sensible guest room choice. As an every-night bed for two it's tight: the UK small double is 15cm narrower than the UK double, and the plush pillowtop encourages each sleeper to sink in where they lie, so you'll notice each other more.
What room size do I need for the small double UltraGel 1000?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open doors and drawers. If your room is a box room, loft conversion or studio where a standard double would dominate, this is exactly the situation the UK small double is designed for.
Is the small double a good upgrade from a single for this mattress?
Often, yes. The UK small double is 30cm wider than the UK single and the same length, so a teenager or adult who has outgrown a single gains real stretching room without the bed swallowing the floor space. The soft, cushioned feel suits lighter bodies and side sleepers particularly well.
