Cocoon by Sealy tip
You have to sleep on the mattress for at least 30 nights before you're allowed to return it — your body needs time to adjust, so don't bother requesting a return in week one even if it feels off.
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.
