Layer Details
- Fits compact rooms: At 90cm wide it slots into small bedrooms and loft conversions with sloped ceilings, and we suggest a room of at least 2.1m x 2.8m.
- A sensible children's and teens' choice: Medium firm gives growing sleepers proper support rather than a sink-in feel, and at 190cm long it will last well beyond a growth spurt.
- Two singles for a shared or guest room: The 90cm width leaves space for a walkway between two beds, which makes it practical for siblings sharing or a guest room set up for two.
- Pocket springs at a single-bed scale: The springs move independently, which means the mattress responds to your weight where you lie rather than tilting you toward the middle.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and they're the most widely stocked and lowest priced bedding of any UK size.
This size suits you if...
You're furnishing a child's or teenager's room and want a supportive mattress that will last through their growing years, you're setting up a spare room or a study that occasionally hosts guests, or you sleep alone in a compact room where a wider bed would crowd out the wardrobe and desk. Allow at least 2.1m x 2.8m of floor space and it should fit comfortably.
Consider another size if...
You're an adult who sleeps alone but likes to stretch out or change position a lot in the night. We'd recommend the UK small double instead: it's 30cm wider, the same length, and needs a room of at least 2.4m x 2.8m.

What are the dimensions of the Copper Arthur UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK single size, so it fits any standard single bed frame, and ordinary single sheets and duvets fit without adjustment.
Will the Copper Arthur UK single fit a bunk or mid sleeper frame?
The width and length match the standard UK single, so the footprint fits most bunk, cabin and mid sleeper frames. Depth matters on raised frames, though, because guard rails need to sit above the mattress surface, and Arthur Sleep doesn't publish a depth for this model. Check the measurement with the retailer before buying for a raised frame.
How much room do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space, which is our own guidance rather than the manufacturer's. That leaves enough clearance to walk around the bed and open drawers or wardrobe doors, even in a child's room where the bed shares space with toy storage and a desk.
Is the Copper Arthur single a good choice for a child or teenager?
It's a reasonable fit. The medium firm feel supports growing backs better than a soft, sink-in mattress would, and pocket springs respond to lighter bodies where foam can feel unyielding. At 190cm long there's plenty of room to grow. Very lightweight side sleepers may find it slightly firm at the shoulder, so bear that in mind.
How much smaller is the UK single than the UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length. If you're weighing them up for a solo adult, we suggest at least 2.6m x 2.8m of floor space for the UK double, so measure your room before sizing up.
