Key benefits
- Fits the smallest rooms: At 90cm wide it leaves floor space free in a child's room where the bed competes with a wardrobe, desk and toy storage.
- Slim enough for raised frames: The 21cm depth sits safely below the guard rail on most bunk and mid sleeper frames, where deeper mattresses often can't.
- Firm support for growing sleepers: The zoned Miracoil system with 323 springs gives a firm, even surface, which suits children and teens who need support rather than sink.
- Double-sided for longer wear: You can flip and rotate it regularly, useful in a guest room or first flat where a mattress needs to last on a small budget.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, so kitting out a spare bed or student room costs very little.
This size suits you if...
You're buying for a child or teenager, especially for a bunk, cabin or mid sleeper frame where the 21cm depth is an advantage rather than a compromise. It also fits if you need a firm, low-cost single for a spare room that doubles as an office, or a student room or first flat where the frame is provided but the mattress isn't.
Consider another size if...
You're an adult sharing the bed, or a solo sleeper who spreads out and finds 90cm restrictive. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Is the Silentnight Essentials Value Mattress in a UK single good for a bunk bed?
Yes, and it's one of the better matches. At 21cm deep it sits below the guard rail height on most bunk, cabin and mid sleeper frames, where many modern mattresses are too thick to be safe. Check your frame's maximum mattress depth before buying, but at 90 x 190cm this is the standard bunk size.
How much room do I need for a UK single Silentnight Essentials Value Mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or a wardrobe. In a loft conversion, the narrow 90cm footprint means the bed can tuck under the slope while the walkway stays where head height is better.
Is the UK single Silentnight Essentials Value Mattress suitable for a child?
Yes, with one caveat. It's the standard UK children's size and the firm, zoned Miracoil support suits growing sleepers well. Very light children may find it a little unforgiving at first, though most adapt quickly. Being double-sided, it can be flipped and rotated to wear evenly through the years a child uses it.
Can two singles work in a shared or guest room?
Often better than one bigger bed. Two 90cm singles give siblings their own space with a walkway between, and in a guest room they suit friends or relatives who wouldn't share a double. The firm feel and low price of this mattress make buying a pair realistic. Just measure for both beds plus the gap.
Is a UK single big enough for an adult?
For most single adults, yes, though 90cm is snug if you spread out. The 190cm length suits anyone up to around six feet; taller sleepers should note the UK single is 10cm shorter than the UK king. For a first flat or a bed you sleep in every night, consider whether the UK small double, 30cm wider and the same length, would be more comfortable.
