## Questions & Answers

**Q: How does an entire mattress fit in a small box?**
A: Lull uses advanced compression technology for easy shipping and instant bounce-back comfort. And don’t worry—you don’t have to fit it back in the box to return it! We’ll schedule a free pickup and donate it to a local charity.

**Q: Does the mattress sleep hot like other memory foam mattresses?**
A: The Lull mattress is designed to keep you comfortable all night long. The top layer of the mattress is made of gel-infused viscoelastic memory foam. This layer provides dramatically enhanced air flow and draws heat away from your body.

**Q: How does the 365 Night Trial work for the mattress?**
A: Try your Lull mattress stress-free for 365 nights. If you don't love it within the first 365 nights, we'll arrange a quick and easy return.

**Q: Do Lull mattresses off-gas harmful chemicals?**
A: All foams used in Lull mattresses are CertiPUR-US Certified, which means that they meet rigorous standards for minimizing off-gassing.

### ⭐⭐⭐⭐⭐ GREAT quality mattress!
*by A***R on February 6, 2026*

My second Lull mattress. My first one was 10 years old. It still was not in to bad of a shape. (It is being used as a cushion on a homemade bench!) I bought the same Lull again. The 10 inch. Love it! It is as perfect as the first one. No smell at all. Not to soft and not to hard. Just right!
