Flaxby Natural Cashmere Vale 15750 Mattress

Assessed from the specification published by dreams.co.uk, captured November 2026, and from regular price comparison across our UK retail partners.

This is a mattress for anyone who wants a natural build and a bit of seasonal flexibility. The cashmere and alpaca wool side is described as temperature regulating, so it suits colder months, while the cotton and mohair side is breathable for warmer nights. Flipping it means you can match the surface to the weather. It's made without glue, chemicals or foam, which will appeal if you want to avoid synthetic materials. The removable mohair pillow top lets you decide how much cushioning you want on the surface. Flaxby says it uses eight natural fibres in total.

If you need to know the firmness before you buy, this might not be the best choice, as Flaxby doesn't publish one. It's also a heavy mattress to handle, because it arrives in two packages weighing 54 kg and 15 kg, and flipping it with the seasons takes some effort. Flaxby doesn't publish a spring count either.
