Layer Details
- Wool comfort layer. Soft, springy British wool sits at the surface and moulds around your body shape. It's naturally breathable yet insulating, which means it helps regulate temperature through the seasons.
- Cotton, hemp and flax blend. Further layers of cotton and wool blended with hemp and flax fibres improve airflow within the mattress. These fibres also wick away moisture, useful if you tend to sleep warm.
- Mini pocket springs. A layer of 14000 mini springs contours to your body for personalised comfort. Because each spring moves independently, there's room for air to circulate too.
- Cortec Quad Revolution pocket springs. An award-winning layer of 1000 springs with a dual design, each in its own pocket and secured into groups of four. They're highly flexible, adjusting to your movement and weight through the night.
- Posturfil springs. A base layer of 1500 Posturfil springs, flexible and adaptable. They sense movement to keep support consistent as you shift position.

- Real room for one: At 120cm wide, a solo sleeper gets generous space to shift and sprawl, and the 14000 mini springs contour to wherever you end up.
- Fits where a double can't: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that clears and one that doesn't.
- Modest room requirement: We suggest a minimum of 2.4m x 2.8m, so a box room, studio or loft conversion can still take a proper adult bed.
- Cool for close quarters: Small rooms trap heat, and the wool, hemp and flax fillings breathe far better than foam, so a snug bedroom needn't mean a warm night.
- Handles the odd shared night: The pocket springs move independently, so two guests sharing occasionally won't disturb each other much, even at this cosier width.
This size suits you if...
You sleep alone most nights, have outgrown a UK single and want genuine stretching room without giving up floor space, or your bedroom can't take anything wider than 120cm. It also suits a guest room where couples stay occasionally rather than nightly, and where the natural, breathable build makes visitors comfortable without the bed dominating the room.
Consider another size if...
You share the bed every night and your room measures at least 2.6m x 2.8m. We'd recommend the UK double instead: it's 15cm wider than the UK small double, the same length, and far more comfortable for two long term.

Is a small double Palladium 16500 big enough for a couple?
For occasional nights, yes. The pocket spring construction keeps movement localised, so neither person feels the other turning. For every night, 120cm across is a squeeze for two adults, especially on a soft to medium surface where you both settle into the springs. Full-time couples should look at the UK double or UK king pages instead.
What room size do I need for the Palladium 16500 in a small double?
We suggest at least 2.4m x 2.8m. That allows walking space around the bed rather than the mattress alone. At 120 x 190cm, it sits comfortably in box rooms, loft conversions and small second bedrooms in rentals or holiday lets, places where a standard double would leave no standing room at all.
Does the small double have the same spring count as the bigger sizes?
Harrison Spinks quotes the same construction across the range: 14000 mini springs in the comfort layers, 1000 Cortec Quad Revolution springs and 1500 Posturfil springs beneath. Spread across the narrower 120cm width, a solo sleeper gets the full contouring effect, and the soft to medium feel doesn't change with size.
Is the small double Palladium 16500 good for a teenager?
It works well for a teenager who has outgrown a UK single, since the UK small double is 30cm wider but exactly the same length, so it often fits the same wall. Whether the premium natural build is justified for that stage of life is your call; it's a considerable spend for a room they may leave.
Where can I buy the Palladium 16500 in a UK small double?
Availability shifts, so the most reliable answer is the live table on this page, which is updated as retailers change their listings and prices. Check the size selected is the UK small double, 120 x 190cm, before you buy, as 4ft frames and fitted sheets differ from standard double ones.
