Spindle offers a full year’s sleep trial, which is more than Nolah, Essentia, Plushbeds, Naturepedic, and Savvy Rest. It is the same, however, as Avocado (for adult mattresses) and Awara. The trial is a comfort guarantee, during which you can contact Spindle to arrange to try a different layer in your mattress. You have to pay shipping for the new layer and to ship back the original layer (this is similar for Savvy Rest and other layered mattresses). Spindle says that around 85 percent of its customers love their mattress right out of the box. Some 13-14 percent realize they need a different level of comfort and need to switch out a layer. That means just 1-2 percent of customers remain unhappy. If, at the end of the year, you’re one of the 1-2 percent and still aren’t comfortable with the Spindle mattress, and you’ve worked with the company to try to remedy the situation, Spindle will refund all your money. Before they do this, though, they require you to cut the tags off the mattress, send them to Spindle, and arrange for your mattress to be donated. They also require proof that the donation is complete before they refund your money.
