Casper helped kick off the bed-in-a-box era, and it remains a sleep company in the fuller sense, mattresses at the core, but also bedding, pillows, and other sleep products designed as a system. Its enduring appeal is the low-risk way it sells a high-stakes purchase: a 100-night risk-free trial, free mattress delivery, and a 10-year limited warranty on mattresses take the anxiety out of buying a bed you can't lie on first. That structure suits online mattress shoppers who want to actually live with a bed before committing, and the trial is genuinely hassle-free, if you're not in love after the 30-night adjustment period, Casper arranges a courier to pack up and remove the mattress on your schedule and refunds your original payment in full, with returned products donated or recycled where possible. The savings landscape mixes sitewide sales with targeted discounts. Seasonal events like the Stay Cool Sale offer 25% off bundles and 20% off the Snow and Snow Max lines, applied automatically on casper.com. A generous referral program lets you give 30% and get 30% by sharing a referral code at checkout. Verified groups, military, first responders, healthcare workers, save through an ID.me-verified discount, and a broader community discount takes 5% off after verification, each issuing a promo code to enter in your cart. New subscribers to the email newsletter get a welcome offer, and Affirm financing brings rates as low as 0% APR for spreading the cost. For a mattress you can test for months with a painless return, Casper is a benchmark. Deals above are taken from Casper's own website and checked before we publish them.

Casper gives you 100 nights to try your mattress at home. You must sleep on it through the first 30-Night Adjustment Period before returning, since new mattresses take time to break in and your body needs time to adjust. If you are still not 100% in love after that, returns are free and your original payment is refunded in full.
No. A courier will pack up and remove the product on your schedule; there's no need to recompress it into the original packaging. The return pickup is complimentary, and your original form of payment is refunded in full. Casper also tries to donate or recycle returned mattresses rather than send them to landfill.
When a friend uses your referral code on their first purchase they get 30% off eligible items, and you receive an email with a code for 30% off one order. It is a give-30, get-30 structure, so both sides save. Your friend can also stack the confidence of the 100-Night Risk-Free Trial and free mattress delivery on that first order.
Yes. Active duty, retirees, veterans, military spouses and family members, as well as nurses, medical professionals and first responders, can verify through ID.me to receive a discount code. Once verified, the code applies at checkout. This community discount is one of several ways to save, alongside the 5% community discount and Affirm financing as low as 0% APR.
Casper mattresses include a 10-Year Limited Warranty, which covers defects in materials and workmanship over the life of the coverage. It works alongside the 100-Night Risk-Free Trial: the trial lets you decide if the mattress is right for you, while the warranty protects against manufacturing defects long after the trial ends.
