Reversible (wool side for year-round temperature regulation, cotton side for warmer months), machine washable, Woolmark certified, hypoallergenic, and fits mattresses up to 15" deep via a fitted elastic skirt.

Wool naturally regulates temperature and wicks moisture — keeping you cool on hot nights and warm on cold ones — while resisting dust mites and mildew without chemical treatments.

WHO THIS IS FOR:

  • Anyone wanting plush comfort and natural temperature regulation on top of their mattress
  • Hot or sweaty sleepers — wool wicks moisture better than synthetic fills
  • Allergy sufferers — hypoallergenic, dust-mite and mildew resistant

FREQUENTLY ASKED QUESTIONS

Is this a mattress topper or a mattress pad?
It functions as both — it's a 1" plush wool layer that adds comfort and temperature regulation on top of your mattress, with a reversible cotton side for warmer months. It sits like a fitted sheet with an elastic skirt, not a thick foam topper.

What is Woolmark certification?
Woolmark is the world's leading wool textile certification, guaranteeing the product contains 100% pure new wool that meets strict quality and performance standards. It's the gold standard for wool bedding authenticity.

Does wool sleep hot?
No — this is one of the most common misconceptions about wool. Wool is a natural thermoregulator: it wicks moisture away from your body and allows airflow, keeping you cool in summer and warm in winter. It outperforms most synthetic fills for temperature regulation.

What's the difference between organic wool and regular wool?
Organic wool comes from sheep raised without synthetic pesticides, hormones, or antibiotics, on land managed without synthetic fertilizers. It's better for the environment, the animals, and for people with chemical sensitivities.

Can I machine wash it?
Yes — it's fully machine washable on a gentle/wool cycle. Use a large-capacity or commercial washer for Queen and King sizes. Avoid bleach and fabric softener. Tumble dry low.

Will it fit my deep mattress?
The elastic skirt fits mattresses up to 15" deep on Queen and King sizes, and up to 13" on Twin, Double, and Twin-XL. If you have a mattress topper already on your bed, measure the combined height before ordering.

Is wool hypoallergenic?
Yes. Wool naturally resists dust mites, mildew, and mold without chemical treatments — making it one of the best choices for allergy and asthma sufferers. It's also naturally fire resistant.

How does this compare to a synthetic mattress pad?
Synthetic pads (polyester, microfibre) trap heat and moisture. Wool regulates temperature, wicks moisture, and is biodegradable. For anyone who sleeps hot or has sensitivities, wool is a significant upgrade over synthetic fills.

Wool pillow and mattress cover

I have had an organic latex mattress and side sleeper pillow for the past 4 years which I really like until I noticed I was starting to get neck and a bit of shoulder as well as back pain this past year. I purchased the wool mattress topper and pillow and problem solved! So comfortable.

Thank You Carolyn - Your feedback is important to let other customers decide too. Did you know you can turn over the mattress pad over to the cotton side since it is reversible too?

Decent, but not what I was hoping

The wool topper was priced right (in comparison to some that were upwards of $900!) but we doubted the authenticity of the “wool.” It is also not as efficient at wicking away heat in the manner we were hoping. You might be better off spending more for higher quality.

Hello Carmen - Thank you for your honest review. This mattress pad is genuinely 100% organic wool. Although wool does help in wicking away moisture I can tell you honestly if you sleep hot no amount of wool can help.
Although this is our best wool mattress pad with 500gsm thick, I don't really know if it's comparable to something that costs three times as much.
Perhaps you can try to turn it over to the other side with cotton since this mattress pad is reversible as well for additional comfort.
