You've got a full 100 days from the delivery date to decide if your Secret Mattress is right for you. We ask that you give it at least 30 nights. Switching from an old, worn-out mattress to our hybrid comfort can take a bit of adjusting. Ready for a return? It's straightforward. Drop us an email at care@secretmattress.com and remember to pop in your order number. If you're still within your 100-night window and your mattress is good condition, we'll give you the green light to donate it to a local charity. Share proof of the donation with us, and voilà, you get a full refund. Plus, someone less fortunate gets a cozy bed. It's a win-win! Just ensure you get our donation approval via email before proceeding. Oh, and about that compact box your mattress arrived in? Toss it! We promise never to make you play mattress Tetris again. Our confidence in our product lets us offer you one of the industry's most RISK-FREE trials. We genuinely believe you'll adore our product. But if it's not a match made in heaven, rest assured we keep things hassle-free. At the heart of it all, your happiness is our ultimate aim.*
