When it comes to mattress shopping, we always advise waiting for a big retail holiday. However, 4th of July sales are still a few weeks out, so if you need to shop for the best mattress right now, Mattress Firm has a killer deal right now. 

For a limited time, Mattress Firm is taking 20% off select mattresses via coupon code “SAVE20”. Plus, use coupon code “ELEVATE” to get a free adjustable base on select purchases. (Eligible purchases are marked as “Free Adjustable Base.” You must manually add the base to your cart). That’s one of the biggest mattress sales and best Mattress Firm promo codes we’ve seen.
