Why should you choose this mattress?
The 1,200 pocket springs move independently, which means the mattress responds to your body and helps cut down on roll-together if you share a bed. The Comfort Breathe fibres encourage airflow, and the knitted cover is breathable too, so it should help hot sleepers stay at a more even temperature. The firm feel suits back sleepers and anyone who likes a supportive, flatter surface, although lighter side sleepers may find it a little unforgiving at the shoulders and hips. Made in the UK and hypoallergenic.

Best suited for?
Back sleepers
The firm feel gives a flatter, supportive surface, which means your body stays evenly held when lying on your back.
Warm sleepers
Breathable Comfort Breathe fibres and a knitted cover encourage airflow, which should help you stay at a more even temperature through the night.
Couples
The 1,200 pocket springs move independently, which means the mattress responds to each person and helps cut down on roll-together when sharing.
Allergy sufferers
The mattress is hypoallergenic, so its fibre layers and cover suit anyone who wants a cleaner sleep surface.
If you prefer sleeping on a soft or plush mattress, this might not be the best choice. It's firm, and the comfort layer is made of fibres rather than thick foam, so there's less cushioning for shoulders and hips. Lighter side sleepers and anyone with sensitive pressure points may find it too hard.
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.
