Key benefits
- Leaves room for everything else: At 90cm wide, the UK single leaves space for a desk, a wardrobe and toy storage in a child's bedroom, with a clear path to the door.
- Cooler foam for warm teenagers: Silentnight says the memory foam is 15% cooler than standard memory foam, which means a teenager who kicks the duvet off at night should feel less stuffy heat building up.
- Zoned support for one body: The Mirapocket springs are arranged in zones, which means hips and shoulders are supported differently, and with one sleeper there's no partner's weight pulling the surface out of shape.
- Two beds in a shared or guest room: A pair of UK singles leaves a walkway between them, so siblings or visiting friends can each have their own bed without one of them sleeping on the floor.
- Fits under a sloping ceiling: The narrow footprint lets you tuck the bed lengthways under the slope of a loft conversion, keeping the full-height part of the room free for standing and dressing.
This size suits you if...
You're furnishing a child's or teenager's room and need floor space for a desk and storage, or you're setting up a spare room that also works as an office. It also suits you if you sleep alone, tend to run warm and want foam cushioning on a spring base.
Consider another size if...
You're a broad-shouldered adult who sprawls, or the guest room regularly hosts couples. We'd recommend the UK small double instead: it's 30cm wider, and we suggest at least 2.4m x 2.8m of floor space.

FAQ's
Will the Silentnight SleepResponse Support 3600 fit a UK single bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK single frames, but Silentnight doesn't publish a depth for this mattress. Raised frames usually state a maximum mattress depth so the safety rail stays high enough above the sleeper. Check the frame maker's guidance and confirm the depth with the retailer before ordering for a bunk, cabin or mid sleeper.
Is the UK single SleepResponse Support 3600 a good mattress for a teenager?
It can be a sensible pick for a teenager who sleeps hot, since the CoolEase cover and graphite-infused foam are aimed at warm sleepers. The zoned springs give a growing body some structure. The catch is that Silentnight doesn't publish a firmness rating, so if your teen has strong views on feel, that's hard to judge in advance.
What size bedroom do I need for a UK single Silentnight SleepResponse Support 3600?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk alongside the bed and open a wardrobe or drawers, which matters in a box room or a child's bedroom where the bed shares the space with a desk.
What bedding fits the Silentnight SleepResponse Support 3600 single?
Standard single sheets fit the 90 x 190cm surface, and a single duvet measures 135 x 200cm. Because Silentnight doesn't publish a depth, look for fitted sheets with generous deep pockets, or check the depth with the retailer, so the corners stay put on the box top design.
Single or small double SleepResponse Support 3600 for a spare room that's also an office?
The UK single keeps the room usable as a workspace, as we suggest at least 2.1m x 2.8m. The UK small double is 30cm wider and the same length, which gives adult guests more room, but we suggest at least 2.4m x 2.8m. If the desk is staying, measure first, then compare the retailers listed on this page for the single.
