Quick Answer: Costco Mattress Return Policy

Costco accepts mattress returns at any time, with no time limit. You get a full refund. No receipt needed — they can look up your purchase with your membership card. Works for both in-store and online purchases.

How the Costco Mattress Return Policy Works

Costco's return policy on mattresses is one of the most generous in retail. Here's exactly what you need to know:

  • No time limit — You can return a mattress 6 months, 1 year, or even 3 years after purchase
  • Full refund — You get 100% of your money back, no restocking fees
  • No receipt required — Your membership card tracks all purchases
  • In-store returns — Bring the mattress to the returns counter. They handle everything
  • Online returns — Schedule a pickup through costco.com or call 1-800-774-2678

In-Store vs. Online Returns: What's Different

Returning In-Store

Drive the mattress to your local Costco warehouse. Go to the returns desk (usually near the entrance). Show your membership card. That's it — they'll process the refund on the spot. Most refunds appear on your card within 3-5 business days.

Pro tip: Bring the original packaging if you still have it. Not required, but it makes the process faster. If your mattress is too large for your car, ask Costco about pickup — some locations offer this for large items.

Returning Online Purchases

  1. Log into costco.com → Orders & Returns
  2. Find your mattress order → click "Return Item"
  3. Choose pickup or drop-off
  4. For mattresses, Costco typically arranges free pickup
  5. Refund processes within 5-7 business days after pickup

You can also return an online purchase in-store — just bring your membership card.

What Costco WON'T Tell You

The policy is generous, but there are a few things worth knowing:

  • They track return frequency — Returning mattresses repeatedly can flag your account for a membership review
  • Mattress must be returned, not just the box — You need the actual mattress
  • Costco.com purchases of certain brands may have different pickup logistics (call first)
  • Some Costco mattresses are online-only — Check if your model is also in-warehouse before driving over
