This mattress makes sense if you want traditional natural materials rather than foam. The Hampshire fleece wool is selected for being thicker and fuller than standard wool, which means a springy, resilient surface rather than the sinking feel of memory foam. Cotton fibres wick away moisture, so if you're a hot sleeper this construction should stay cooler than synthetic alternatives. The 2000 pocket springs move independently, distributing support to each part of the body, helpful if you and a partner are different weights. It carries a 10-year guarantee, is a National Bed Federation Approved Brand and conforms to BS7177: 2008 for fire resistance. Yes, it's firm, but that's exactly what many buyers with back complaints are after.
Key Features & what's inside
- Comfort Layer. Natural Hampshire fleece wool, specially selected for being thicker and fuller than standard wool, which means a springy, resilient feel underneath you. Wool also has natural temperature-regulating properties, so it works across seasons.
- Comfort Layer. Natural cotton fibres create a fresh sleeping environment, regulating body temperature and wicking away moisture. In practice, that means less of the clammy feeling you can get with synthetic layers.
- Support System. 2000 individually hand-nested pocket springs work actively to distribute personalised support to each part of the body. Because each spring moves on its own, you're less likely to feel a partner shifting during the night.

Who's it NOT for?
This isn't the one for lightweight side sleepers, who may find the firm feel puts pressure on hips and shoulders. If you love the slow, cradling sink of memory foam, an all-natural sprung mattress like this will feel quite different. It also needs turning, so anyone who struggles to rotate a mattress should factor that in.

How firm is the Millbrook Wool Luxury Ortho 2000?
The product page describes it as firm, and owner reviews suggest it feels softer when pressed by hand but firm under full body weight. It's best suited to back and stomach sleepers, or side sleepers with a heavier build. Lightweight side sleepers may find it slightly too solid.
Does the Millbrook Wool Luxury Ortho 2000 come with a trial?
Mattress Online lists a 100-night trial, but this is the retailer's own offer rather than a Millbrook guarantee, and it requires buying a mattress protector from them. If you purchase elsewhere, check that retailer's terms before you commit.
How deep is the Millbrook Wool Luxury Ortho 2000 mattress?
It's 28cm deep. That's a generous depth, so check your fitted sheets will stretch to accommodate it, particularly if you're used to a slimmer mattress.
Does the Millbrook Wool Luxury Ortho 2000 need turning?
Yes, and it comes with practical turning handles, which owners mention appreciating in reviews. Regular rotation helps natural fillings like wool and cotton settle evenly, so it's worth building into your routine.
What guarantee does the Millbrook Wool Luxury Ortho 2000 have?
The Mattress Online listing states a 10-year guarantee. That's reassuring cover for a mattress at this price, though as with any guarantee, keep your proof of purchase and follow the care instructions.
