Layer Details
- Wool. Soft, springy British wool moulds around your body shape, which means the surface adapts to you rather than pushing back. It's naturally breathable yet insulating, so it helps regulate temperature across the seasons.
- Cotton, Wool, Hemp and Flax blend. Additional layers of cotton and wool blended with hemp and flax fibres improve airflow within the mattress. They also wick away moisture, keeping the sleep surface drier and fresher.
- Mini Pocket Springs. A layer of 14000 mini springs contours to your body for personalised comfort. Because they're springs rather than foam, air can still move through the layer.
- Posturfil Springs. These 1500 Posturfil springs are highly flexible and adaptable, sensing movement as you shift position. In practice that means the mattress responds to you through the night rather than leaving you to settle into one spot.
- Cortec Quad Revolution Pocket Springs. The base layer uses 1000 award-winning Cortec Quad Revolution pocket springs, a dual design with mini springs placed inside regular springs. Each sits in an individual pocket, secured in groups of four, which means support stays localised to where your body needs it.

- A gentle feel at a single width: The soft to medium surface suits lighter bodies, which makes this size a sensible match for teenagers and smaller adults sleeping alone.
- Natural fillings for one warm sleeper: Wool, cotton, hemp and flax breathe and wick moisture, useful in a small bedroom where air can get stuffy overnight.
- Full spring construction, compact footprint: You get all three spring layers, including the 1000 Cortec Quad Revolution pocket springs, in a mattress just 90cm wide.
- Fits where larger sizes cannot: At 90 x 190cm it leaves room for a desk or wardrobe, and two singles can share a room where one double would dominate.
- Check depth on raised frames: At 29cm this is a deep mattress, so measure carefully before pairing it with a bunk, cabin or mid sleeper frame.
This size suits you if...
You sleep alone and want natural fillings and a softer feel rather than a budget single, you're buying a long-term mattress for a teenager who sleeps on their side, or you're furnishing a guest room properly and want visitors to sleep as well as you do.
Consider another size if...
You're an adult who has the space and would rather not sleep within a 90cm width every night. 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.

How big is the Palladium 16500 in a UK single?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in. It's the standard one-person size, so standard single sheets and a single duvet fit without hunting for special bedding. We suggest allowing at least 2.1m x 2.8m of floor space so you can move around the bed comfortably.
Is the Palladium 16500 UK single suitable for a child or teenager?
The soft to medium feel suits lighter bodies well, and lighter sleepers press less deeply into the fillings, so a teenager should get proper support from the spring layers. It's a considerable spend for a child's room, but the handcrafted construction is built to last through those years.
Will the Palladium 16500 single work on a bunk or mid sleeper frame?
The width is right, but at 29cm deep this is a taller mattress than most raised frames are designed for. On a bunk it can sit above the safety rail, and on a cabin or mid sleeper it changes the climb. Measure the rail height before buying.
Is the UK single Palladium 16500 a good guest room mattress?
Yes, with one caveat. The natural fillings and layered springs will give guests a genuinely comfortable night, and two singles fit a spare room more flexibly than one double. The caveat is cost: it's a premium mattress, so it makes most sense if the room also serves you regularly.
How does the UK single compare to the small double for one adult?
The UK single is 30cm narrower than the UK small double, and both are the same 190cm length. If your room can take it, that extra width gives a solo adult noticeably more room to spread out; we suggest at least 2.4m x 2.8m of floor space for the UK small double.
