Why our sleep experts loved it
Millbrook have taken their long standing experience designing luxury mattresses and combined it with the latest manufacturing techniques to create a truly luxurious mattress that's built to last in the Millbrook Wool Luxury 1000 Pocket Mattress.
I got my hands on this one in person and the first thing that struck me was how 'proper' it feels, it's got that traditional, well-made Millbrook vibe rather than feeling like a boxed mattress pretending to be luxury.
Each layer of this handcrafted mattress is made using the finest materials to ensure exceptional comfort and support, whether you're sleeping on your back or your side.
Running my hand across the cover it felt smooth and tightly finished, and when I pressed down with my palm I could feel the pocket springs pushing back individually rather than the whole surface dipping at once.
The Millbrook Wool Luxury 1000 Pocket Mattress is designed to combine the pressure relieving comfort of pocket springs with the warmth and breathability of wool and cotton. The mattress offers a medium to firm feel and is 25cm deep giving enough room for a good quality pocket spring layer with it's individually wrapped coils to be able to offer sufficient support.
On my back it felt nicely level through the hips and lower back, but on my side I could feel that medium-firm tension a bit more around the shoulder, so if you're lighter in weight or very bony at the shoulder you might find it a touch too firm without a topper.
It is also worth being aware that wool can feel a bit 'springy' and buoyant compared to memory foam, so if you like that slow sink-in hug, this isn't really that sort of mattress.
The surface provides an even support across the entire sleeping surface which combined with the air vents helps to provide a cool, fresh sleeping environment.
Sitting on the edge to mimic putting socks on, the support was decent but not rock solid, you can feel the edge compress a bit, which is normal for a more traditional build. For the money I'd also like to see proper turning handles, because at 25cm deep it isn't the easiest thing to spin around on your own.
