## Questions & Answers

**Q: What does the cooling gel infusion do, and will it keep my mattress cooler?**
A: Cooling gel is blended into the foam to help draw heat away from your body and regulate sleep temperature. The open-cell foam structure and ventilation channels also promote airflow for a cooler sleep experience than traditional memory foam.

**Q: Is there an odor when it arrives, and how long until I can sleep on it?**
A: A mild new-foam scent is normal and fades quickly. Unroll in a ventilated room for 24–48 hours. By the time it fully expands, the smell should be gone.

**Q: Will my current sheets still fit?**
A: Measure your mattress plus your topper height before ordering sheets to ensure a snug fit. The added height may require deep-pocket sheets (15"+ depth).

**Q: Which thickness is right for me — 2", 3", or 4"?**
A: The 2" adds subtle softness to a slightly firm mattress. The 3" delivers deeper pressure relief for back and side sleepers. The 4" is ultra-plush, ideal for very firm or worn mattresses.

**Q: Can I wash this topper?**
A: The foam can't be machine washed. Spot clean with mild detergent and a damp cloth. We recommend pairing it with a waterproof mattress protector to keep it fresh long-term.
