The 30-Night Guarantee

Try It for 30 Nights. If Your Sleep Doesn't Improve, Return It.

We stand behind every product in the Rest Theory catalog. If you use a product consistently for 30 nights and your sleep doesn't improve, we'll take it back and refund you in full. No forms, no return shipping labels, no questions.


What's Covered

  • All Rest Theory products purchased directly from resttheory.store
  • Full purchase price refunded — no restocking fees
  • Applies to the original purchaser within 30 days of delivery
  • One return per household per product category

How to Return

Email us at support@resttheory.store with your order number and a brief description of your experience. That's it. We'll confirm within 24 hours and process your refund within 3–5 business days of your email.

You don't need to ship the product back. We trust that if you're asking for a refund, you tried it and it didn't work for you. That's enough.


What's Not Covered

  • Consumable products — Sleep Strips (Mouth Tape) are single-use and cannot be returned once opened. If you received a damaged or defective batch, we'll replace it free of charge.
  • Products purchased through third-party retailers (Amazon, other platforms) — contact that retailer directly for their return policy.
  • Damage caused by misuse or modification of the product.

Why We Do This

Sleep is personal. What works in a controlled study doesn't always work in your bedroom, with your schedule, next to your partner. We can't know in advance which products will work best for you — and we don't think you should bear the financial risk of finding out.

The 30-night guarantee exists so that price is never the reason you don't fix your sleep.
