Casper Promo Codes & Mattress Discount Codes

1. Buy while a site-wide sale is running

   Up to 25% off mattresses (Oct 2026 sale)Low effortEveryone

   Casper's sale prices show on the product pages without a code, and its Promotional Details page lists what each sale covers and when it ends. On October 17, 2026 the Friends & Family Sale took 20% off The One and Cloud One and 25% off Dream, Snow, Dream Max and Snow Max, plus 30% off bundles and adjustable bed frames, through October 21, 2026 at 11:59pm PT. It leaves out Final Sale and Clearance items, the Nap Pillow, the Original Foam, Original Hybrid and Element mattresses and digital gift cards, and can't be combined with another offer.^{[1, 2]}

   1. Open the Promotional Details page on casper.com for the current sale and its end date.
   2. Check that the model you want isn't on the excluded list.
   3. Compare the dollar price, since the percentages are measured against Comp. Value.

2. Buy the mattress, base and protector as a bundle

   30% off bundles (Oct 2026 sale)Low effortAnyone who needs a base as well as a mattress

   During the Friends & Family Sale, which ends October 21, 2026, bundles of a mattress, a foundation or adjustable base and a mattress protector were 30% off, while a foundation bought on its own was 10% off. Bundling also stretches the base's trial: furniture normally has 30 nights, but gets the mattress's 100 nights when bought with it. The catch is that a bundle can only be returned whole, and the referral and Upgrade Program codes don't apply to bundles.^{[1, 2, 3, 4, 5, 11, 12]}

3. Ask about a price match if a sale starts during your trial

   The sale price, if your order qualifiesSome effortBuyers still inside the 100-night trial

   Casper's Promotional Details page says that if you spot a sale during your 100-Night Trial, you can contact its Sleep Specialists to find out whether your order is eligible for a price match. It's a question, not a promise, so ask with your order details at hand.^{[1, 4]}

   1. Note your delivery date: the trial runs 100 nights from it.
   2. When a new sale appears on casper.com, contact Casper by chat, at support@casper.com or on 1-888-498-0003.
   3. Ask whether your order is eligible for a price match.

4. Use a friend's referral link on your first order

   30% off your first orderLow effortFirst-time Casper customers in the US, 18 or older

   Through Casper's Refer a Friend program, a new customer who follows a friend's invite link and enters an email gets a one-time code for 30% off their first order on casper.com; the friend then receives a 30% code for one order. The code excludes bundles, Final Sale and Clearance items, the Nap Pillow, the Snug, Original, Original Hybrid and Element mattresses, digital gift cards and Casper Outlet purchases, and it doesn't stack with other discounts.^{[11, 14]}

   1. Ask a friend to send you their invite link from Casper's Refer a Friend page.
   2. Follow the link and enter your email to get your code.
   3. Apply it at checkout on your first casper.com order and compare the total with the sale price.

5. Verify with ID.me for the Community Discount

   5% offLow effortMilitary, teachers, students, healthcare workers, first responders

   Casper's Community Discount takes 5% off for active duty, veterans, retirees, military spouses and family members; teachers and students; and nurses, healthcare professionals, first responders and hospital employees. You verify through ID.me and get a code to paste into your cart. It excludes Clearance and Final Sale products and can't be combined with other offers: Casper accepts one discount code per order.^{[7, 8]}

6. Owners: use the Upgrade Program code after a year

   10% off plus a free pillowLow effortPeople who have owned a Casper mattress for over a year

   If you've owned a Casper mattress for more than a year, the Upgrade Program gives an extra 10% off a purchase that includes a mattress, plus a free Original Pillow (king size with a king or California king). Casper emails the code on your one-year anniversary if you're on its email list, or you can call 888-498-0003. Bundles, Clearance, Final Sale, the Snug, Original Hybrid, Original Foam and Element mattresses and digital gift cards are excluded, with one code per person.^[12]

Codes and offers kept by David Jones, who keeps this guide's deals current.

Casper puts sale prices straight on its product pages and lists its live offers on its own Promotional Details page; its terms say codes promoted by unauthorized third-party sites aren't valid. We list only the dated sales Casper publishes on casper.com, each with its end date.

  Ends Oct 21, 2026

1. No mattress returns in the first 30 nights

   The 30-Night Adjustment Period is part of the trial: Casper doesn't accept a mattress return before it ends, and the request has to come by night 100.^[4]

2. Sale percentages are measured against Comp. Value

   Casper bases its savings on Comp. Value, which it defines as a price at which Casper or third parties have offered the item or a comparable one. Judge a deal by the dollar price you pay.^{[1, 2]}

3. A return can cost you the next trial

   Casper's terms say that once you return a product from an order, you and your shipping address lose the trial period on later orders of that same product — return a pillow, and the next pillow comes without one.^[14]

4. Clearance means no trial and a shorter warranty

   Clearance runs at 30–75% off, but items marked Final Sale or Clearance can't be returned or exchanged except for a defect, and a clearance mattress is covered for 5 years instead of 10.^{[15, 16]}

5. Some charges stay paid after a return

   The $249 in-home delivery and setup fee isn't refunded if the products go back. Neither is the state recycling fee that California, Connecticut, Oregon and Rhode Island add to each mattress, foundation and bed frame.^{[5, 6, 18]}
