Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This is a mattress for people who want natural materials and a gentler feel without giving up proper support. The wool and hemp fillings wick away moisture and allow airflow, which means it should sleep cooler than a foam-heavy alternative. If you're a hot sleeper, that matters. The spring system is unusually layered: 14000 mini springs contour closely to your shape, 1500 Posturfil springs adapt to movement, and 1000 Cortec Quad Revolution springs provide the deeper support. It conforms to BS7177: 2008 and Harrison Spinks is a National Bed Federation Approved Brand. Yes, the from-price of £1,569 is a serious outlay, but you're paying for handcrafted UK construction and steel rather than synthetic comfort layers.
Key Features & what's inside
- 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.

Who's it NOT for?
If you prefer a firm surface, this soft to medium feel is unlikely to suit you, particularly if you're a heavier back or stomach sleeper who needs more pushback. It's also a poor fit for tight budgets: even the smallest size starts at £1,569. Anyone wanting an all-foam feel should look elsewhere too.
Harrison Spinks Palladium 16500 Pocket Mattress (Soft to Medium Feel)

How firm is the Harrison Spinks Palladium 16500?
It has a soft to medium feel, which suits side sleepers and lighter bodies who need the surface to cushion shoulders and hips. Combination sleepers should also get on with it, although stomach sleepers and anyone who likes a firm mattress may find it a little too yielding.
What is the Harrison Spinks Palladium 16500 made of?
Natural fillings of British wool, cotton, hemp and flax sit over three spring systems: 14000 mini springs, 1500 Posturfil springs and 1000 Cortec Quad Revolution pocket springs. The natural fibres breathe and wick moisture, which means it should stay cooler than a foam mattress. It's handcrafted in the UK and 29cm deep.
Does the Palladium 16500 come with a trial period?
MattressOnline lists a 100-night trial on this mattress. That trial is the retailer's own offer rather than a Harrison Spinks policy, so if you buy elsewhere, check that seller's terms before ordering.
What guarantee does the Harrison Spinks Palladium 16500 have?
The mattressonline.co.uk listing states a 5 year guarantee followed by a 5 year warranty, giving 10 years of cover in total. As this appears on a retailer listing, it's sensible to confirm the exact terms with the seller you buy from.
What sizes does the Palladium 16500 come in?
It's available in UK Single, Small Double, Double, King and Super King, with prices ranging from £1,569 to £3,029 depending on the size you choose.
