Question 1

How does the cooling actually work?

Accepted Answer

Our patented phase-change weave absorbs body heat and disperses it through an open-cell airflow channel — keeping the surface up to 7° cooler than a standard topper, all night, without electricity.

Question 2

Will it fit my mattress?

Accepted Answer

The deep elastic skirt fits any mattress between 6" and 18" thick. Choose Single, Double, Queen, or King to match your bed.

Question 3

Is it machine washable?

Accepted Answer

Yes — the entire cover is machine washable on a cool, gentle cycle. Tumble dry low. We recommend washing every 2–3 months.

Question 4

How long does it take to ship?

Accepted Answer

All orders ship within 24 hours from our US warehouse. Free standard shipping arrives in 3–5 business days.

Question 5

What is the return policy?

Accepted Answer

Sleep on it for 30 nights risk-free. If it's not for you, contact us for a full refund — we cover return shipping. No restocking fees.

How is this different from Eight Sleep?

Accepted Answer

Yes — every btrrsleep topper comes with a 5-year warranty against manufacturing defects.
