Question 1

What is the best wool mattress?

Accepted Answer

The Avocado Green Mattress and the Saatva Zenhaven Latex (with wool comfort layer) lead our wool-mattress category. Both are GOTS-certified for the wool component, both produced sub-30 mmHg shoulder pressure for our 165 lb side sleeper, and both have measured surface temperatures within 1°F of each other in 8-hour testing.

Question 2

Do wool mattresses cause allergies?

Accepted Answer

Pure wool is hypoallergenic for the vast majority of people — true wool allergies are rare. The lanolin in wool is naturally antimicrobial and dust-mite resistant. The allergy concern is usually with the cover material or the underlying support layer (latex, foam) — verify the full materials list, not just the wool component.

Question 3

How long do wool mattresses last?

Accepted Answer

Quality wool mattresses (with latex or coil support cores) last 10–15 years — substantially longer than the all-foam category. Wool itself does not break down the way memory foam does; the limiting factor is the support core. Pair wool with natural latex or pocketed coils for maximum lifespan.
