Layer Details
- Cover. Made from sustainably sourced natural cotton with a natural fire retardancy treatment. That means no chemical fire treatments next to your skin.
- Comfort layer. Hand tufted with British wool to create a smooth, sturdier surface. Tufting anchors the fillings in place, which means fewer lumps developing over time.
- Comfort fillings. Finely filled with sustainably sourced cotton fibres. These are highly breathable and wick away moisture, which helps you stay dry and comfortable overnight.
- Solotex™ layer. A recycled synthetic fibre spun to create a breathable, durable filling. It adds a soft, plush layer above the springs.
- eOlus™ fibres. Made from recycled plastic bottles, these bring extra comfort while reducing landfill waste. A small sustainability win baked into the build.
- Support system. 1200 ReActive 6-turn pocket springs, which means each spring responds to your body independently for even support. Rod edging around the unit firms up the perimeter.

- Fits where space is tight: At 90cm wide it leaves room for a desk, wardrobe or toy storage in a compact bedroom, which is where most UK singles end up.
- Grows with a child: The 1200 ReActive pocket springs respond to each body independently, so a lighter child gets even support rather than sinking into a firm slab.
- Cooler for teens and guests: British wool and cotton fillings wick away moisture, which means a warmer sleeper wakes up dry rather than clammy.
- Usable right to the edge: Rod edging firms up the perimeter, useful on a narrow 3ft mattress where every centimetre of sleeping surface counts.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or teenager and want natural fillings and proper spring support rather than a budget foam slab, you sleep alone and your room can't comfortably take anything wider than 90cm, or you're furnishing a spare room that has to double as an office and needs the floor space back during the day.
Consider another size if...
You're an adult who shifts around at night, because 90cm is a snug width for restless sleepers. 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.

How big is the Hypnos Burford Ortho Comfort in a UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits standard single frames, single fitted sheets and a 135 x 200cm single duvet. We suggest a room of at least 2.1m x 2.8m so you can still open drawers and walk around it.
Will the Hypnos Burford Ortho Comfort single fit a bunk or mid sleeper frame?
The width and length match standard bunk frames, but at 27cm this is a deep mattress, and many bunks specify a maximum depth so the guard rail still sits safely above the surface. Check your frame's stated maximum before buying, particularly for a top bunk or a child's mid sleeper.
Is the Hypnos Burford Ortho Comfort UK single a good choice for a child or teenager?
For most, yes. The medium firm feel keeps a growing spine level, and the breathable wool and cotton fillings suit teenagers who run warm. A very light child who sleeps on their side may find it slightly firm on shoulders and hips, so it's better suited from the later primary years onwards.
Is a UK single big enough for an adult guest room?
For occasional guests, comfortably. At 90cm wide it's the classic spare room size, and two singles fit where one larger bed plus a walkway wouldn't, handy if you host couples or siblings. The rod edging helps here too: a guest perched on the side won't feel the perimeter give way.
How much wider is the UK double than this single?
The UK double is 45cm wider than the UK single, and the two are the same length at 190cm. If you're deciding between them for a solo adult, the UK double needs a room of at least 2.6m x 2.8m, so measure first: in a small bedroom the extra width can cost you a wardrobe.
