Spring King Wool Luxury Soft 3000 Mattress
The Spring King Wool Luxury Soft 3000 is a soft pocket sprung mattress with deep wool fillings, which means a gently cushioned, sink-in feel rather than a firm, on-top-of-the-bed one.

At 28cm deep, the Spring King Wool Luxury Soft 3000 has a generous profile, and the wool is naturally breathable, so it insulates without trapping heat. It comes in five UK sizes, from Single to Super King. It's hypoallergenic, made in the UK, and comes with free next day delivery and a 1-year guarantee. If you sleep on your side, or you simply prefer a softer surface, this is the sort of feel it delivers.

Why should you choose this mattress?
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 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 & layer details
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.

Best suited for?
Side sleepers
Deep layers of plush wool cushion your body at every point of contact, which suits the shoulders and hips of anyone who sleeps on their side.
Warm sleepers
Wool insulates while staying naturally breathable, so you get warmth in winter without feeling clammy or overheated when the weather turns warmer.
Couples
Individually pocketed springs move independently, which means each one responds on its own and reduces the disturbance you feel when a partner shifts position.
Allergy sufferers
The mattress is hypoallergenic, so the natural wool and pocket spring build suits anyone who wants a cleaner sleep surface without synthetic-feeling comfort.
Lighter sleepers
A soft feel with pocket springs that respond to your weight means lighter bodies sink in gently and get cushioning rather than a hard surface.
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.
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 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.
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.
