Millbrook describes the Wool Luxury 1000 as medium to firm, which suits back and stomach sleepers who want support without a hard, unyielding feel. At 25cm deep with 1000 hand-nested pocket springs, it's a classic natural-filled build rather than a foam-heavy modern hybrid. The price is reasonable for hand-tufted wool fillings. Mattress Online offers a 100-night trial on it, so you can change your mind if the natural feel isn't for you.

Why should you choose this mattress?
This mattress makes sense if you want natural materials at a sensible price. The Hampshire wool and cotton fillings breathe well, which means you're less likely to overheat than on synthetic foam, and wool helps regulate temperature across the seasons. The 1000 pocket springs each move independently, so your partner's tossing and turning is less likely to disturb you. Hand-tufting keeps the fillings anchored, which reduces sagging over time, and the mattress is approved by the National Bed Federation and conforms to BS7177: 2008 for fire resistance. Mattress Online lists a 10-year warranty and a 100-night trial, the retailer's own terms rather than Millbrook's, but a genuine safety net all the same.
Key features & layer details
Cover
A soft-touch cotton-viscose cover infused with M-Pure, a 100% plant-based, sustainable treatment. This gives a breathable sleeping surface rather than a synthetic one.
Comfort fillings
Layers of 100% fleece wool sourced from Hampshire, blended with layers of cotton and hand-tufted. Tufting anchors the fillings in place, which means less shifting and settling over the years.
Support system
1000 individual hand-nested pocket springs, each encased in cloth pockets. Because each spring moves on its own, the mattress responds to your shape and limits motion transfer between partners.

Best suited for?
Back sleepers
The medium to firm feel gives steady support under the hips and spine without a hard, unyielding surface, so you stay level overnight.
Front sleepers
Medium to firm tension keeps the midsection from sinking too far, which suits stomach sleeping where you want support without a stiff feel.
Couples
Each of the 1000 pocket springs moves independently, which limits motion transfer, so one partner's tossing and turning is less likely to wake the other.
Warm sleepers
Hampshire wool and cotton fillings breathe well and help regulate temperature across the seasons, so you are less likely to overheat than on synthetic foam.
Eco-conscious buyers
Natural Hampshire fleece wool and cotton fillings, plus a cover with a plant-based M-Pure treatment, give a mostly natural build rather than a foam-heavy one.
If you prefer the slow, cradling sink of memory foam, this traditional sprung feel will seem quite different, and firmer. Lightweight side sleepers may find medium to firm a little unforgiving on shoulders and hips. And if a new-mattress smell bothers you, some owners mention a temporary wool-like odour at first.
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.
