Why should you choose this mattress?
The springs are split into seven zones, which means support is shaped to different parts of your body rather than being the same all over. The pillow top adds a cushioned layer, so the surface feels softer than the medium rating alone might suggest. Natural materials include Hampshire wool, silk, cotton and Cashgora. Integrated side air vents help air move through the mattress. It's single-sided with turning handles, so you won't need to flip it. Overall it suits most back and side sleepers, although anyone wanting a very firm feel may find it too cushioned.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Side sleepers
The hand-tufted pillow top adds a cushioned layer, so the surface feels soft under shoulders and hips while the medium rating keeps support underneath.
Back sleepers
Seven zoned spring areas shape support to different parts of your body, which means your back is held evenly instead of the mattress feeling the same all over.
Warm sleepers
Integrated side air vents help air move through the mattress, and the natural fillings of wool, silk and cotton work alongside them to keep the sleeping surface comfortable.
Eco-conscious buyers
Natural fillings including Hampshire wool, silk, cotton and Cashgora are used throughout, along with a Belgian Damask viscose cover, so there is less reliance on synthetic padding.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium and has a pillow top, so the surface is cushioned. It's also single-sided, so you can't flip it. It arrives flat rather than rolled and boxed, which may matter if access to your room is tight.
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.

How deep is the Millbrook Sovereign Natural Pillow Top?
It's 31cm deep. That's a fairly substantial mattress, so check your bed frame and any fitted sheets you plan to use will suit that depth.
