What Happens If I Order the Wrong Size Costco Mattress? 

Costco encourages you to measure before buying a new mattress. This helps to prevent any extra shipping or the headache of re-ordering. That being said, Costco’s return policy is focused on the complete satisfaction of customers. This means if you don’t like your mattress or got the wrong size, you can bring in the mattress for a full refund. 

Another option is to have it hauled away. This is only available for some mattresses, though, so you’ll have to call customer service. Schedule a time for it to be picked up and then you can get your refund.
