Comparison
Two 100-night mattress trials, and the difference inside them
Both stores advertise a hundred nights. Only one lets you give up in the second week. What matters here is not the headline number but the conditions attached to it — read from the stores' own refund policies in October 2026.
| Zinus | Sweetnight | |
|---|---|---|
| Mattress trial | 100 nights from delivery | 100 nights, with a mandatory 30-night adjustment period before an opened mattress can be returned |
| Everything else | 30 days on toppers, frames, adjustable bases and furniture | Toppers follow a 30-day trial; unopened items 30 days |
| Condition required | Good condition, no stains, proof of purchase | Sanitary and donatable, free of stains, tears or excessive wear |
| Ships to | United States | United States only |
| Worth knowing | Buy a mattress protector on day one; the condition requirement is real | Returns for reasons other than quality are not covered |
