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 shared size that fits most rooms: At 135 x 190cm, the UK double leaves space for wardrobes and drawers in rooms where a UK king would dominate.
- 67.5cm each for two people sharing: That's the width each sleeper gets, and the 14000 mini pocket springs contour to each body individually, so you feel your side rather than your partner's.
- Natural fillings across the full 135cm: Wool, cotton, hemp and flax breathe and wick moisture, which matters when two bodies share a surface this size all night.
- Room for bedside tables on both sides: In a room around 3m x 3m, a UK double usually leaves enough clearance for a table each, something a wider bed often rules out.
- Easy to dress and easy to buy for: Double sheets and a 200 x 200cm duvet are stocked everywhere, so replacing bedding never becomes a hunt.
This size suits you if...
You share the bed every night and your room sits comfortably within our suggested 2.6m x 2.8m minimum, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since the soft to medium feel is forgiving for side sleepers of different builds.
Consider another size if...
You and your partner both toss and turn, or one of you is broad shouldered and 67.5cm each feels tight. We'd recommend the Palladium 16500 in a UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

Is a UK double Palladium 16500 big enough for two adults?
Yes, for most couples. Two people sharing get 67.5cm of width each, and the layered pocket springs keep support localised, so movement on one side carries less to the other. If either of you sleeps restlessly or you're used to sprawling, the UK king's extra 15cm of width will feel noticeably calmer.
What room size do I need for the Palladium 16500 in a UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That larger footprint usually leaves clearance for bedside tables on both sides plus a wardrobe, which is exactly why the UK double remains the default choice for typical UK bedrooms.
Will the UK double Palladium 16500 get up narrow stairs?
It's a 29cm deep pocket spring mattress, so it flexes far less than foam and can't be rolled or folded. In an older terrace with a turning staircase, or a new build with a tight landing, measure the awkward point before ordering and check the retailer's delivery access requirements.
Should a couple choose the double or the king in this mattress?
If your room comfortably exceeds 3m x 3m and you both value space, the UK king adds 15cm of width and 10cm of length. If space is tighter, or you want tables both sides, the UK double is the better balance of bed against room. The soft to medium feel is identical in both.
