Assessed from the specification published by Feather & Black, captured September 2026, and from regular price comparison across our UK retail partners.
You are getting five layers of pocket springs, including micro, Posturfil and Cortec designs, which means the mattress adapts closely to your shape while relieving pressure at the hips and shoulders. The fillings are entirely natural: wool, cotton, flax and hemp, with a chemical-free wool and viscose sleeping surface, so no synthetic foams sit near your skin. Buying through Feather & Black, you get free two man delivery to the room of your choice, a 100-night trial and a 7-year guarantee, all on that retailer's own terms. Sizes go from UK Single right up to Emperor, useful if you need something larger than a standard Super King.
Key Features & what's inside
- Sleeping surface. A chemical-free surface blended from wool and viscose. It sits directly beneath you and helps regulate temperature through the night.
- Natural fillings. Generous layers of British wool, breathable cotton, naturally cooling flax and farm-grown hemp. These fillings wick moisture and keep air moving, which means fewer clammy nights.
- Pocket springs. 9,690 responsive springs across five layers, combining high-density micro, Posturfil and Cortec pocket springs. Each spring moves independently, so the mattress adapts to your body, relieves pressure and lets air circulate.

Who's it NOT for?
This is a firm mattress, so lightweight sleepers and dedicated side sleepers may not sink in enough for proper pressure relief at the shoulder. And with prices starting at £1,899, it is not the choice if you are shopping on a tight budget. It also needs regular head to foot rotation, so factor in that upkeep.

How firm is the harrison spinks owen mattress?
It is described as firm on the Feather & Black listing. That suits back and front sleepers, and heavier bodies generally, although lightweight side sleepers may find it a little too solid for comfortable shoulder sink.
Does the harrison spinks owen mattress need turning?
The Feather & Black listing describes it as a no turn mattress, so you never need to flip it over. That said, the same page recommends rotating it regularly head to foot, which helps the natural fillings settle evenly.
Does the harrison spinks owen come with a trial?
Feather & Black lists a 100-night trial and a 7-year guarantee. These are that retailer's own offers rather than manufacturer terms, so if you buy elsewhere, check what that shop provides before ordering.
How many springs does the harrison spinks owen have?
It has 9,690 pocket springs arranged in five layers, mixing high-density micro, Posturfil and Cortec designs. More layers of smaller springs mean the surface responds to your shape more precisely than a single layer of larger springs would.
What sizes does the harrison spinks owen come in?
Six sizes: UK Single, Small Double, Double, King, Super King and Emperor. Prices range from £1,899 to £3,899 depending on the size you choose.
