Savvy Rest doesn't allow returns unless there's a manufacturing defect. This is because the company would want to sanitize returns for resale, and it's not willing to do that because of its chemicals policy. While laudable, this avoidance of chemicals needn't mean no returns or refunds. Plenty of other, much smaller, mattress companies do allow returns; they just donate usable products to charity rather than reselling mattresses. Happily, there's a bit of wiggle-room for the Serenity. Savvy Rest does offer a 90-day Latex Exchange program, meaning you can switch a layer to reconfigure the mattress. You have to pay an upgrade fee for Talalay latex though and pay shipping both ways.
