You can return a mattress to Costco for a full refund for any reason — except normal wear and tear. This policy applies to regular mattresses and air mattresses.
Costco Mattress Return Policy Explained
Mattresses fall under Costco’s “risk-free, 100% satisfaction guarantee” and can be returned at any time and for any reason that isn’t routine wear and tear, according to Costco’s corporate customer service department. We also contacted several Costco Warehouse stores to confirm this information.
To make a return, you can bring the mattress (including air mattresses) to any Costco location or you can sign in to your Costco.com account and fill out a return request (free return shipping is available).
While a receipt can help expedite the return, you can return an item without a receipt; a store associate can access your purchase history by looking up your membership account.
Once your return is accepted, you will be refunded in full, including shipping and handling charges when applicable.
Keep in mind that if your mattress has normal wear and tear, Costco can refuse the return. This means that you can’t return a mattress you’ve been using for a few years just because you want a new one.
