Luxury Hampshire wool

Millbrook have carefully selected Hampshire fleece wool for this stunning mattress. A unique, single black Hampshire wool tuft signifies the inclusion of this premium wool inside.

Locally sourced from Hampshire lambs, this wool is thicker, fuller and more resilient than standard wool - for a more comfortable night's sleep, the natural way.

Naturally breathable, wool is the ideal comfort material to keep you warm in winter and cool in summer. Blended with layers of English cotton, the Wool Luxury 4000 is truly luxurious.

Traditionally hand-tufted, this mattress locks in all the plush comfort and provides enhanced support.

Pocket sprung support

Good postural support is essential for a healthy night's sleep. The Wool Luxury 4000 features a remarkable 4000 pocket spring system with a ErgoZone 7 design. The zoned design offers firmer support around your hips, head and feet. This firmer feel is achieved through thicker gauge wires with stronger tension. The design stops these areas of your body from sinking in and resulting in an uncomfortable sleep posture. The softer zones offer lighter support and optimise the sumptuous feeling without compromise. Designed to respond to your pressure points to deliver ultimate comfort and promote natural spinal alignment.

Since each pocket spring is individually encased, they actively work throughout the night to support your body with highly responsive and targeted support. Pocket springs are considered a superior spring system - and for good reason! There's no roll-together or roll-off, and you won't feel your partner's movements as you sleep. It's the perfect recipe for a peaceful night's sleep.

Optimised sleep space

Maximised sleeping space is a must for a good night's sleep - whether you sleep with your partner or you get the bed to yourself!

Complete with metal rods that sit above and below the pocket spring unit and are held in place with butterfly clips. This design reinforced the durability and stability of the mattress edge to stop it from sinking when met with weight or pressure. So you can enjoy edge-to-edge support without a 'roll off' feel.

Stylish design

The Wool Luxury 4000 is finished with a beautifully soft-touch cotton-viscose fabric cover. It'll become a stunning feature in your bedroom and it truly looks as good as it feels.

Easy care for your convenience

Complete with built-in turning handles, it's easy to move your new mattress. As it's double-sided, we recommend that you flip your mattress regularly to keep it in great condition.

Quality you can trust

Handmade by expert craftspeople in the UK, this mattress has been produced to the highest standards. The cover is infused with M-Pure, a 100% natural, plant-based treatment that's naturally fire resistant.

Sleep soundly: it's approved by the National Bed Federation, too!
