The Harrison Spinks Salisbury 10750 uses 10,750 springs alongside natural fillings including Egyptian cotton, British wool and mohair sourced from Harrison Spinks' own Yorkshire farm. It's a serious spend, but you're paying for chemical free natural materials and a turnable design that should reward regular flipping with a longer usable life. It arrives flat rather than rolled and boxed, so it needs two people to get it upstairs. Harrison Spinks is an NBF-approved manufacturer and the mattress carries a 10-year guarantee, as stated on the MattressNextDay listing.

Why should you choose this mattress?
This mattress makes sense if you want natural materials and long-term durability rather than foam. The Cortec pocket springs sit between layers of micro springs, which means the surface responds to pressure a bit like foam does, but with the airflow of an all-spring build, useful if you tend to sleep hot. It's turnable, with the same wool, cotton and mohair fillings on both sides, so you can flip it to even out wear. The wool is certified traceable under British Wool's Traceability Scheme, which matters if provenance is part of your decision. The medium firm feel suits most back and combination sleepers, although lightweight side sleepers may find it slightly too firm.
Key features & layer details
Cover
An in-house woven, chemical free Belgian damask cover, which means the sleeping surface stays breathable rather than trapping heat. It's a natural fabric rather than a synthetic knit.
Comfort fillings (top side)
Layers of Egyptian cotton, white British wool and mohair, responsibly sourced from Harrison Spinks' Yorkshire farm. These fibres wick moisture, which means a drier, more temperature-stable feel through the night.
Micro and Micro HD springs
Springs small enough to behave like a foam, targeting pressure points with accuracy. They sit above the main pocket spring system to soften the initial feel.
Cortec™ Pocket Springs
Individually pocketed springs developed by in-house engineers, which means each spring moves independently and adapts as you change position through the night. This is the supportive core of the mattress.
Micro and Micro HD springs
A second layer of micro springs beneath the pocket spring system, mirroring the layer above. This sandwich construction is what makes the mattress fully double-sided.
Comfort fillings (bottom side)
The same Egyptian cotton, British wool and mohair fillings repeated on the underside. You can flip the mattress and sleep on either face, which helps the fillings settle evenly over time.

Best suited for?
Warm sleepers
Cortec pocket springs sit between layers of micro springs, giving the airflow of an all-spring build, while the wool and cotton fillings wick moisture to keep the night cooler.
Eco-conscious buyers
Chemical free Belgian damask, Egyptian cotton, British wool and mohair from a Yorkshire farm mean natural materials throughout, with the wool certified traceable under British Wool's scheme.
Back sleepers
The medium firm feel and individually pocketed Cortec springs give steady support that adapts as you move, which suits sleeping flat on your back.
Combination sleepers
Each pocket spring moves independently, so the surface adapts as you change position, and the medium firm feel works well when you switch between sleeping positions.
Allergy sufferers
A chemical free woven cover and natural fillings of cotton, wool and mohair suit anyone who wants to avoid synthetic foams and treated fabrics in their bed.
Skip this one if you're on a tight budget, or if you want a mattress you can set up alone: it arrives flat, not rolled, and a 28cm double-sided sprung mattress is heavy to manoeuvre. If you prefer a deep memory foam hug, you won't find that feel here either.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Harrison Spinks Salisbury 10750 firm or soft?
It's rated medium firm, which suits most back and combination sleepers. The micro springs soften the surface a little, so it shouldn't feel like a board, but lightweight side sleepers who need deep pressure relief may find it slightly too firm.
Do you need to flip the Harrison Spinks Salisbury mattress?
Yes, it's a turnable, double-sided mattress with the same cotton, wool and mohair fillings on both sides. Flipping it regularly evens out wear on the natural fillings, which is part of why double-sided mattresses tend to last well.
Does the Harrison Spinks Salisbury 10750 come with a guarantee?
The MattressNextDay listing states a Harrison Spinks 10-year guarantee. Free next day delivery and old mattress removal on that page are the retailer's own offers, so check terms with whichever shop you buy from.
Is the Harrison Spinks Salisbury 10750 delivered rolled up in a box?
No. It arrives flat, which is normal for a traditional sprung mattress with natural fillings, as rolling would damage them. That does mean you'll want two people on hand for delivery day, particularly for stairs and tight corners.
What sizes does the Harrison Spinks Salisbury 10750 come in?
It's available in ten sizes: UK Small Single, Long Small Single, Single, Small Double, Double, King and Super King, plus EU Single, EU Double and EU King.
