Why should you choose this mattress?
The main draw is the build. The filling is Swaledale sheep's wool grown in Yorkshire on Harrison Spinks' organic farm, and Flaxby designs the mattress without glue, chemicals or foam, which suits you if you want a natural mattress with no synthetic padding. The firm comfort grade gives a solid, supportive feel, so it should suit most back sleepers, although lighter side sleepers may find it a little unyielding. It's also recyclable at end of life, and more than 20 bedmakers craft each one, which points to careful construction. The 33cm depth gives it a substantial feel.
Key features & layer details

Best suited for?
Eco-conscious buyers
Swaledale wool filling, no glue, chemicals or foam, and recyclability at end of life give a natural build that suits anyone wanting less synthetic material.
Back sleepers
The firm comfort grade gives a solid, supportive feel, which should suit most people who spend the night lying on their back.
Allergy sufferers
A wool filling with no foam and no synthetic padding may appeal to anyone who wants a simpler, more natural sleep surface.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It has a firm comfort grade, which can feel unforgiving to lighter side sleepers who like a cushioned surface. It's also a premium mattress, and Flaxby doesn't publish a spring count, so you can't compare its support with other pocket spring models.
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.
