What is the Best Super King Mattress for Me?

We have two different ranges, at Woolroom: Classic and Artisan.

Our Classic: models provide an affordable entry to the world of wool sleep. Individual pocket springs, micro coils and super soft Wool ID® traceable British wool work together to give you all the support you'll need during the night.

Our Artisan*: range features mattresses hand-crafted by the industry's best. Each is carefully filled with a blend of Wool ID® traceable British wool, cotton, cashmere and silk. Hand-tied pocket springs boost breathability and provide precision contouring, while hand-stitched sides create edge-to-edge support, so there's more space for you to really make yourself comfortable.

Sleeping Positions

Choosing the best super king mattress for you will largely depend on what type of sleeper you are.

If you sleep on your side, you’re more likely to benefit from a soft super king mattress or a regular model. It’ll provide support at the shoulders, hips and lower back.

Regular mattresses are ideal for those who sleep in a combination of positions on or on their backs. Sleep on your stomach? You’ll get the most comfort from a super king firm mattress – as it provides an increased amount of support.
