Assessed from Spring King's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Wool is the headline here. Deep layers of it cushion your body at every point of contact, and because wool insulates while staying breathable, it keeps you warm in winter without making you clammy in summer. Beneath that, individually pocketed springs move independently, which means each one responds to your weight and movement on its own, giving pressure relief where you need it and reducing disturbance from a partner. The mattress is hypoallergenic and meets the BS7177: 2008 fire safety standard, and starting at £359 it's a reasonable route into natural-fibre comfort. The 1-year guarantee is short, but the build itself, wool and pocket springs at 28cm deep, is a solid combination for the money.
Key Features & what's inside
- Quilted Cover. The cover is stitched together with the fillings beneath it, creating a patterned comfort quilt layer. In practice, that means the soft surface feel is built in rather than sitting loose on top.
- Wool. Deep layers of plush wool cushion your body at every point of contact. Wool insulates well, keeping you warm and snug, while its breathable structure helps prevent overheating.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, a little like piano keys. This targets pressure relief precisely, adjusting to your movements and how your weight is distributed.

Who's it NOT for?
This is a genuinely soft mattress, so if you prefer a firm, supportive surface, sleep mainly on your front, or carry more weight and need extra pushback, look elsewhere. The 1-year guarantee is also shorter than most brands offer, which may put off buyers wanting long-term cover.

How firm is the Spring King Wool Luxury Soft 3000 mattress?
It's rated soft, which means a cushioned, cradling feel rather than firm support. That suits side sleepers and lighter builds well, although some owner reviews mention it feels slightly firmer than expected for a soft mattress.
Is the Spring King Wool Luxury Soft 3000 good for hot sleepers?
It should cope reasonably well. The wool fillings insulate to keep you warm, but wool is naturally breathable, so the design helps prevent overheating rather than trapping heat the way some synthetic fillings can.
How deep is the Spring King Wool Luxury Soft 3000 mattress?
It measures 28cm deep, a generous profile that reflects the deep wool fillings and pocket spring unit inside. Standard fitted sheets should still work, though deep-fitted sheets will give a neater finish.
What sizes does the Spring King Wool Luxury Soft 3000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices range from £359 to £809 depending on the size you choose.
Does the Spring King Wool Luxury Soft 3000 have a guarantee?
Yes, it comes with a 1-year guarantee, which is shorter than most brands offer. Free next day delivery is included.
