Layer Details
Pillow top
A stitched pillow top finished in a soft knit cover infused with aloe vera. It adds a softer surface feel on top of the firm mattress.
Memory foam comfort layer
A thin memory foam layer that Silentnight badges as pressure relieving. It gives some cushioning at the surface without losing the firm feel.
Mirapocket pocket spring unit
Individual springs, each in its own fabric pocket, working independently. This gives zoned support that responds to the part of your body pressing on it.

Key benefits
- Space for a desk and a wardrobe: At 90cm wide, the UK single leaves floor beside the bed free, which means a small bedroom can still fit somewhere to do homework and somewhere to put clothes.
- Firm, zoned support for one: The Mirapocket springs move independently and are zoned, which means a solo sleeper's shoulders and hips are held separately rather than the whole bed dipping together.
- Two singles for flexible guests: A pair of UK singles in a spare room lets you host two friends or two children, each on their own firm surface, without forcing anyone to share.
- Easy, inexpensive bedding: Standard single sheets and a single duvet (135 x 200cm) fit this mattress, so dressing a guest bed or a student room needs nothing specialist.
- Check raised frames first: At 39cm deep, this mattress is a tall option for a bunk, cabin or mid sleeper, so confirm the frame's maximum mattress depth and rail height before ordering.
This size suits you if...
You sleep alone and prefer a firm bed with a bit of softness at the surface, you're furnishing a child's or teenager's room where every bit of floor counts, or you're fitting out a spare room that also serves as a study.
Consider another size if...
You share a bed, or you want room to spread out on a firm surface. The UK small double would suit you better: it's 30cm wider at the same length, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the Silentnight SleepResponse Support 1400 single fit a bunk bed or mid sleeper?
The UK single matches the 90 x 190cm footprint most bunk and mid sleeper frames take, but the mattress is 39cm deep. Many raised frames set a maximum mattress depth so the safety rail stays high enough above the sleeper. Check the frame maker's limit first, and if it's lower than 39cm, choose a shallower mattress for that bed.
What size bedroom do I need for a UK single SleepResponse Support 1400?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk around the bed and open a wardrobe in a typical child's room or box room. Two singles for siblings or guests need noticeably more, so measure for both beds plus a walkway between them.
Is a UK single big enough for an adult on its own?
For one adult of average height, usually yes. The UK single measures 90 x 190cm, or 3ft x 6ft 3in. If you're tall, bear in mind it's 10cm shorter than the UK king. If you just want more width to turn over on a firm bed, the UK small double adds 30cm at the same length.
What bedding fits the SleepResponse Support 1400 in a UK single?
Standard UK single fitted sheets and a single duvet, which measures 135 x 200cm, fit this size. Because the mattress is 39cm deep, look for fitted sheets with a deep pocket so the corners stay tucked under. A shallow sheet may ride up at the edges, especially on a stitched pillow top.
How much smaller is a UK single than a UK double for this mattress?
The UK single is 45cm narrower than the UK double, at the same length. The UK double gives two sharing 67.5cm each, and we suggest at least 2.6m x 2.8m for it. If you sleep alone in a small room, the UK single keeps much more floor free; compare the retailers listed on this page once you've measured.
