Layer Details
- Comfort Layer. Soft white synthetic fibres sit on top, which means a cosy initial feel without the sink of memory foam. They're designed to be durable and resilient, holding their shape over time.
- Support System. Traditional open coil springs are interlaced in a lattice design, joined together so the whole surface moves as one. That spreads your weight evenly, easing built-up pressure and helping spinal alignment, though you'll feel more partner movement than with pocket springs.

- Fits the smallest rooms: At 3ft wide it slots into a box room or under a loft slope while leaving space for a desk, wardrobe and toy storage.
- A sensible child's mattress: The medium firm open coil support suits growing backs, and the soft fibre top gives a cosy feel without the sink of memory foam.
- Easy to move and rotate: A UK single is the lightest standard size to carry upstairs or flip end to end, useful for bunk beds and cabin frames.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and lowest priced of any UK size, which keeps the ongoing cost down too.
- Guest ready without fuss: For a spare room that doubles as an office, or two singles for visiting family, its simple construction does the occasional-use job well.
This size suits you if...
You're buying for a child or teenager, furnishing a guest room or student flat, or you sleep alone in a room where every centimetre of floor space matters. It also suits a bunk, cabin or mid sleeper frame, provided the 24cm depth sits safely below the guardrail, and anyone who wants a straightforward, low-cost mattress for a bed that isn't slept on every night.
Consider another size if...
You're an adult sleeping in it every night and you like room to spread out, or you occasionally share the bed. We'd recommend the UK double instead, which is 45cm wider; allow at least 2.6m x 2.8m of floor space for it.

Is the Classic Gold UK single a good mattress for a child?
It's a sensible fit. The medium firm open coil support gives even, consistent support for a growing child, and the soft fibre comfort layer adds cosiness without deep sink. Children are also light enough that the simple spring system holds up well. At 90 x 190cm it leaves room in a child's bedroom for a desk and storage.
Will the Classic Gold UK single fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. The point to check is depth: at 24cm the Classic Gold is deeper than some bunk-specific mattresses, so measure your frame's guardrail height and check the frame maker's maximum mattress depth before buying, particularly for a top bunk.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around and open drawers or wardrobe doors. That makes it one of the few sizes that works in a box room, under a loft slope, or in a spare room that also has to hold a desk.
Is the UK single big enough for an adult?
For one adult, usually yes. At 90 x 190cm, or 3ft x 6ft 3in, it's the standard UK one-person size, and the Classic Gold's medium firm feel suits back and stomach sleepers. Taller adults should note the 190cm length before buying, and anyone who spreads out in the night may prefer more width.
Should I get the Classic Gold in a single or a small double?
It depends on the sleeper and the room. The UK single is 30cm narrower than the UK small double and the two are the same length, so the small double buys width, useful for a teenager or an adult who wants stretching room. Allow at least 2.4m x 2.8m of floor space for the UK small double.
