Layer Details
Mohair
Soft mohair sits near the sleep surface, which means a luxurious feel underneath you. It also helps regulate temperature through the night.
Wool
Naturally insulating British wool keeps you warm in winter. It's a traditional filling for good reason.
Cotton
Breathable cotton draws heat away in summer. Paired with the wool, it means the mattress adapts across the seasons rather than trapping warmth.
Hemp and Flax
Hemp and flax add further natural loft alongside the mohair, cotton and wool. These plant fibres round out an entirely natural filling stack.
Pocket Springs
10,590 responsive springs form the support core, combining high-density micro, Posturfil and Cortec pocket springs. Each spring moves independently, which means support that follows your shape and less disturbance from a restless partner.

Key benefits
- A footprint that leaves room to live: At 90cm wide, the UK single leaves space for a wardrobe, desk or toy storage in rooms where every metre matters.
- Natural fillings for growing sleepers: Mohair, British wool, cotton, hemp and flax regulate temperature without synthetic layers, a reassuring build for a child's or teenager's bed.
- A guest bed that feels generous: Two UK singles fit a spare room where one larger bed would not, and the 10,590-spring core means guests get proper support rather than a compromise.
- Bedding is cheap and easy to find: Standard single sheets and a 135 x 200cm duvet fit, the most widely stocked and affordable bedding of any UK size.
- Check the depth on raised frames: The Conrad is 29cm deep, so measure guard rails on bunk, cabin and mid-sleeper frames before you buy, as many are designed for shallower mattresses.
This size suits you if...
You're buying for one sleeper, a child, a teenager or a single adult, and want a natural-filled mattress rather than foam. It also makes sense in a spare room that doubles as an office, or a loft conversion where only a narrow footprint fits under the slope, provided you can allow at least 2.1m x 2.8m of floor space.
Consider another size if...
You're an adult who moves around in the night or shares the bed even occasionally, as 90cm is snug for one and impossible for two. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m for it.

FAQ's
Is the Harrison Spinks Conrad in a UK single a good choice for a child's room?
For the size, yes: the UK single is the standard children's bed size, and its 90cm width leaves floor space for a wardrobe, desk and toys in a small room. The natural fillings breathe well for warm sleepers. Do consider tension though: the listed version is Firm, which lighter children may find unforgiving, so look at the Soft or Medium options.
Will the UK single Conrad fit a bunk or mid-sleeper frame?
The width matches, since bunks and mid sleepers take standard UK single mattresses at 90 x 190cm. The catch is depth. The Conrad is 29cm deep, and many raised frames specify a maximum mattress depth so the guard rail still does its job. Measure from the base to the top of the rail before buying, and check the frame maker's guidance.
What room size do I need for a UK single mattress like this?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around the bed and open drawers or wardrobe doors. That makes it one of the easiest sizes to place: box rooms, loft conversions with a sloping ceiling, and spare rooms that also hold a desk can usually take it comfortably.
Should I choose the UK single or the UK small double for one adult?
The UK single is 30cm narrower than the UK small double, and both are the same length at 190cm. If you're a restless sleeper or simply like space to spread out, that extra 30cm is noticeable, and we suggest allowing at least 2.4m x 2.8m of floor space for the UK small double. In a tight room, the UK single wins.
Is a UK single big enough for a guest room?
Yes, and it's often the smarter choice. Two UK singles fit where one large bed wouldn't, so a spare room can sleep two guests who'd rather not share, or one bed can sit against the wall leaving space for a desk. At 90 x 190cm each, allow walkway space between them; standard single bedding keeps the linen cupboard simple too.
