Casper is one of the most popular bed-in-a-box brands, and for good reason. It offers some of the best mattresses you can buy for every type of sleeper, shipped straight to your door. It's also a more reasonably priced option, especially if you can find a good Casper coupon or promo code.

Our mattress expert has tested dozens of beds, the Casper lineup included. He does more than just sleep on them — he holds them to an objective testing process involving measuring edge support, breathability, temperature retention, motion isolation, and more. Each model is designed with different features, meaning models like the Casper Snow are great for hot sleepers, while the Casper Element best suits stomach and back sleepers.

Although the biggest savings events of the year are over, Casper is still holding a holiday sale to help make mattress buying a little easier. But that's not all — if you apply one of the coupons I've gathered below, you can save an additional chunk on your new mattress. While something like a 5% discount may not sound like much, it's worth remembering that these stack on top of the retailer's ongoing sales, and with prices well over $500, that small percentage marks a hefty savings.

Today's best Casper coupons and promo codes

• Save an extra 5% with the code BRWSBDN-EXTRA5
• Get an extra 5% off with the promo code CABDN-PR-EXTRA5

As of writing, these are the best Casper coupons you can score on your next purchase. I've put them to the test and found that they work on already-discounted items, so you can save an extra 5% in addition to Casper's ongoing 20% off holiday sale. Coupon codes cannot be combined, so you'll only be able to apply one to your cart.

How to use Casper coupons and promo codes

Casper coupons are pretty easy to use. Copy the code you're planning to apply. Add the product you're buying to your cart, then click on "Apply promo code" to open the entry field. Paste your discount code there and click apply.

Can you stack Casper coupon codes?

Casper coupon codes are not stackable, meaning you can only apply one to each purchase you make. With that in mind, it's important to use the best one available to you.

Luckily, the coupon codes work with any ongoing Casper sales.

Can I use Casper coupons in-store?

Casper coupon codes vary in whether they can be used in-store. Most often, they are limited to online use, but in-store associates can price-match any discounts you have proof of.

What mattress should I buy from Casper?

Do Casper mattresses have a warranty?

Casper offers a 10-year limited warranty that automatically comes with mattresses purchased on Casper.com. It covers defects including abnormal deterioration, physical flaws in the foam, and manufacturing errors in the zipper assembly. If you purchased your bed from another retailer, you can register your bed here.

Final sale and clearance items receive a shorter warranty than other purchases.

What is Casper's returns/refunds policy?

Casper's return policy aims to be as painless as possible by being free anytime after the 30-night adjustment period. Just reach out to support within the first 100 nights of your purchase to have the brand remove the mattress from your home and provide a full refund.

Other products, like pillows, sheets, and accessories, can be returned by printing out a given shipping label and sending it back for free.

Does Casper offer free shipping?

Every mattress order with Casper receives free, no-contact delivery. As the term "bed-in-a-box" suggests, each mattress arrives tightly coiled in a box for you to place on your bed and unfurl.

Other items like headboards and bed frames can incur a shipping fee depending on where you live. Learn more about the specific costs here.

Does Casper offer white glove delivery?

Casper offers an in-home delivery and setup service starting at $199. After placing your order, you can schedule a delivery date for two to four weeks in the future. From there, you'll receive a four-hour delivery window the day before so you can be prepared for your new product's arrival.
