We’ll be the first to admit it: no mattress can be perfect for everyone. And that’s exactly why our 100-Night Trial exists to make your decision pressure-free—so you can focus on sleep, not second-guessing.

At Sunday, we’ve spent years refining three thoughtfully engineered mattresses designed to suit most sleep styles. And the good news? Over 95% of our customers genuinely love their choice.

But what about the rest?

There’s a small percentage—low single digits—who don’t fall in love with their Sunday mattress. Maybe it feels a touch too firm. Or perhaps a bit too soft. Either way, we understand. Comfort is personal, and your bed should feel just right.

That’s why we’ve made our return process simple, transparent, and genuinely stress-free. If you’re not sleeping well, we’ll pick it up and refund the full amount. No awkward questions, no hoops to jump through.

Returns, the Sunday way

Most mattress companies talk a good game about trial periods. We actually mean it. At Sunday, we welcome returns with the same warmth as we welcome orders. After all, your trust matters more than any sale.

Return rates are consistent across all three models:

Why do some people return their mattress?

It mostly comes down to feel—too firm, too soft, or just not “the one.” And honestly? That’s okay. We’re not here to push a one-size-fits-all solution. We’re here to help you discover what good sleep feels like—for you.

No regrets, just rest

If Sunday doesn’t work for you, we’ll make things right. But if it does (and it usually does), you’ll join thousands of well-rested folks who found their match in a mattress built with care, curiosity, and a whole lot of research.
