Sweet Zzz Mattress tip
You must sleep on the mattress at least 30 nights before you're allowed to start a return - trying to return in week one won't be accepted even if you already hate it.
Zinus tip
If you bought your Zinus mattress through Amazon, Walmart, Costco, or another retailer instead of Zinus.com directly, this policy doesn't apply to you — that retailer's own return window and process governs your purchase instead.
