Collection: Mattresses

Eighteen mattresses across six ranges, with three feels in every one of them. Memory, Latex, Gel Hybrid, Natural, Pillow Top, and the Knightsbridge flagship. Every mattress is built to order in our own British factory on a pocket spring core, and carries a 15 year guarantee.

What separates the ranges is the surface you lie on. What separates the three within each range is how far you sink into it. Memory contours to you and holds it. Latex gives and returns. Gel Hybrid is built for people who sleep hot. Natural layers wool, cotton, silk, cashgora and horsehair over latex. Pillow Top adds a separate cushioned layer sewn on the top. The Knightsbridge takes all of it further, with up to 13,450 springs under a removable pillow top.

If you are not sure which you want, that is normal, and it is what the firmness scale on this page is for. Or ring us on 0800 470 4615 and tell us how you sleep. We have been making these for over fifty years.
