The Harrison Spinks Fitzgerald's fillings include fully traceable British wool, cotton, hemp and flax grown on Harrison Spinks' own farm, and the whole thing measures a generous 35cm deep. It's a serious investment, so it suits buyers who want longevity and natural materials over a bargain. It's a no-turn design, though you'll want to rotate it head to foot now and then.

Why should you choose this mattress?
Choose the Fitzgerald if you sleep firm and care about what's inside your mattress. The fillings are traceable British wool, cotton, hemp and flax, natural fibres that breathe well, which means less of the clammy warmth you can get with synthetic foams. The six layers of pocket springs, 11,000 in total, give a firm surface that still relieves pressure at the shoulders and hips. Feather & Black lists a 100-night trial and a 7-year guarantee with free two-man delivery to your room of choice, though those are the retailer's own terms rather than Harrison Spinks'. Yes, it's expensive, but the spring count, depth and farm-sourced fillings go some way to justifying it.
Key features & layer details
Pillow top surface
A deeply filled pillow top with micro springs and natural fillings, which means a softer, cloud-like feel at the surface before you reach the firmer support below. This takes the edge off the firm rating for the first few centimetres.
Natural fillings
Fully traceable British wool and cotton, plus hemp and flax sourced straight from the Harrison Spinks farm. Natural fibres like these help the mattress breathe, which means a cooler night if you tend to overheat.
Pocket springs
11,000 responsive springs in dynamic layers of high-density micro, Posturfil and Cortec™ pocket springs. Six layers adapt to your body as you sleep, relieving pressure while letting air move through the mattress.

Best suited for?
Warm sleepers
Natural fillings of wool, cotton, hemp and flax breathe well, which means less clammy warmth than you can get with synthetic foams.
Eco-conscious buyers
Fully traceable British wool and cotton, plus hemp and flax grown on Harrison Spinks' own farm, make the fillings easy to trace.
Back sleepers
A firm surface from 11,000 pocket springs keeps support under the spine, while the pillow top adds a little give at the surface.
Heavier sleepers
Six layers of high-density pocket springs and a deep 35cm build give a firm, responsive base that adapts as you move.
Couples
Individually working pocket springs adapt to each body as you sleep, relieving pressure at the shoulders and hips on both sides of the bed.
This is a firm mattress, so lightweight side sleepers may find it a little unforgiving despite the pillow top. It's also a significant spend, and at 35cm deep it may sit taller than some fitted sheets allow. If you want a soft, sink-in feel, look elsewhere.
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
How firm is the Harrison Spinks Fitzgerald mattress?
It's rated firm, although the pillow top surface, filled with micro springs and natural fillings, gives a slightly softer initial feel. It suits back and front sleepers and heavier builds best, while lightweight side sleepers may find it a touch too firm.
How many springs does the Harrison Spinks Fitzgerald have?
It has 11,000 springs in total, arranged across six layers combining high-density micro, Posturfil and Cortec™ pocket springs. In practice that means the mattress responds to each part of your body separately, relieving pressure rather than moving as one surface.
Does the Harrison Spinks Fitzgerald come with a trial and guarantee?
Feather & Black, the retailer we've found listing it, offers a 100-night trial and a 7-year guarantee. These are the retailer's own terms rather than a Harrison Spinks promise, so check the conditions wherever you buy.
Do you need to turn the Harrison Spinks Fitzgerald mattress?
No, it's a no-turn mattress, so you never need to flip it over. The retailer listing does recommend rotating it head to foot from time to time, which helps the fillings settle evenly and keeps the surface feeling consistent.
What sizes does the Harrison Spinks Fitzgerald come in?
It's available in UK Single, Small Double, Double, King, Super King and Emperor. The mattress is 35cm deep, so it's worth checking your fitted sheets will stretch that far.
