Mattress Firm Coupons & Sales

First, go to the Mattress Firm website or app. Add item(s) to your Mattress Firm cart, then click on checkout. Look for the promo code, coupon code, or discount code field on the checkout page. Enter the Mattress Firm promo code into that field, then hit the apply button.

There are several potential cases where a promo code may not work at Mattress Firm:

1. It might not be valid without reaching a minimum spend amount.
2. It might not be valid on specific items in your Mattress Firm shopping cart.
3. It might only be valid for first-time Mattress Firm customers.
4. It might be past its expiration date.*

If a Mattress Firm promo code doesn’t work at checkout, try another one if more are listed. Alternatively, you can try these promo code hacks to see if one of them works. You can also try abandoning your cart (while logged in) to see if Mattress Firm sends you an email with a coupon code as an incentive to complete your order.

*At Dealhack, we do the best we can only to show active promo codes, but there are some cases where codes can slip through the cracks.
