Millbrook Wool Ortho 1000 Pocket Mattress

Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.

The main draw here is genuine firm support built from natural materials. The 1000 pocket springs are hand-nested and individually encased in cloth pockets, which means each one responds to your body separately rather than the whole surface moving as one. Above them, 100% Hampshire fleece wool and English cotton wick moisture and regulate temperature, useful if you tend to sleep warm. It's approved by the National Bed Federation and double-sided, so you can flip it to even out wear, something many modern mattresses no longer allow. Yes, firm won't suit everyone, but for back sleepers and heavier builds who find softer mattresses let them sink too far, that firmness is precisely the point.

Back sleepers
Firm support from 1000 pocket springs keeps the body level instead of letting it sink, which suits anyone who finds softer mattresses too yielding.

Heavier sleepers
Individually encased springs under a firm feel resist sinking too far, so heavier builds get steady support that responds to each part of the body.

Warm sleepers
Hampshire fleece wool and English cotton wick moisture and regulate temperature, which means less of that clammy feeling on warmer nights.

Couples
Every pocket spring moves on its own, so you get less disturbance when a partner shifts position during the night.

Eco-conscious buyers
Natural fillings of Hampshire fleece wool and English cotton sit above the springs, giving a mattress built mostly from natural materials and approved by the National Bed Federation.

This is a genuinely firm mattress, so lightweight side sleepers are likely to find it too hard on the shoulders and hips. If you prefer a cushioned, sink-in feel or the contouring of memory foam, look elsewhere. Being double-sided, it also needs turning regularly, which some people would rather avoid.

How firm is the Millbrook Wool Ortho 1000 Pocket mattress?

It's rated firm, and owner reviews back that up, describing it as properly firm rather than medium-firm in disguise. That suits back sleepers and heavier builds well, although lightweight side sleepers may find it a little too solid for comfortable pressure relief.

Does the Millbrook Wool Ortho 1000 come with a trial?

Mattress Online offers a 100-night trial. That's the retailer's own policy rather than a Millbrook guarantee, so if you buy elsewhere, check that seller's terms before ordering.

Is the Millbrook Wool Ortho 1000 mattress double-sided?

Yes, it's double-sided with turning handles, so you can flip it to even out wear and extend its life. That's increasingly rare, as most modern mattresses are one-sided, but it does mean a bit of regular effort on your part.

What sizes does the Millbrook Wool Ortho 1000 come in?

Six UK sizes: small single, single, small double, double, king and super king.

How long is the guarantee on the Millbrook Wool Ortho 1000?

The Mattress Online listing states a 10-year guarantee, which gives you long-term reassurance on a mattress at a mid-range starting price. As with any guarantee, keep your proof of purchase and follow the care instructions, including regular turning.
