Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw is the sheer amount going on inside. The Cortec Quad Core spring system uses 10,750 pocket springs, each in its own breathable fabric pocket, which means support that follows your body closely rather than pushing back as one unit. The fillings are entirely natural, and wool, silk and flax breathe well, which should suit you if you tend to sleep warm. Yes, the price is high, but you are paying for handcrafted UK construction approved by the National Bed Federation, not marketing. If you like a softer, more cushioned feel with proper support underneath, this is aimed squarely at you. Firmer-mattress fans should look elsewhere.
Key Features & what's inside
- Cover. A fine wool-viscose cover, chosen for its supreme softness. It is the first thing you feel, and it sets the gentle tone for the rest of the mattress.
- Comfort fillings. Luxurious natural fillings including silk, mohair, Yorkshire wool, cotton, hemp and flax. Natural fibres like these breathe and wick moisture, which means a cooler, drier feel through the night than most synthetic foams.
- Support system. 10,750 pocket springs using Harrison Spinks' award-winning Cortec Quad Core spring system, with each spring nestled within a breathable fabric pocket. Springs that move independently respond to each part of your body, so a heavier hip sinks in while a lighter shoulder stays supported.

Who's it NOT for?
This sits at the soft to medium end, so if you prefer a firm surface, or you sleep mainly on your front and need to keep your hips from dipping, it is unlikely to suit. The price is also a genuine barrier: from £1,494, it is a considered purchase rather than a budget refresh.
Harrison Spinks Saltaire 10750 Pocket Mattress
How firm is the Harrison Spinks Saltaire 10750?
It is described as soft to medium on the product page. In practice that means a cushioned, sink-in surface with support coming from the 10,750 pocket springs beneath, which suits side sleepers and lighter bodies particularly well.
Does the Saltaire 10750 come with a trial?
Mattress Online, which sells this mattress exclusively, lists a 100-night trial and a 5 year guarantee. These are the retailer's own terms rather than a Harrison Spinks offer.
What is the Saltaire 10750 made of?
Natural fillings of silk, mohair, Yorkshire wool, cotton, hemp and flax sit over 10,750 pocket springs using the Cortec Quad Core system, all wrapped in a fine wool-viscose cover. The mattress is 30cm deep and handcrafted in the UK.
Is the Harrison Spinks Saltaire 10750 good for hot sleepers?
It should be. The fillings are natural fibres such as wool, silk and flax, which breathe and manage moisture better than most synthetics, and each spring sits in a breathable fabric pocket. Owner reviews mention temperature regulation as a strength.
What sizes does the Saltaire 10750 come in?
UK Single, Double, King, Super King and Emperor, with prices from £1,494 to £3,297 depending on size.
