## Questions & Answers

**Q: Will the quality depreciate over time and is there a warranty on this topper?**
A: We have tested our products over a 10 year cycle and don't see any significant degradation of the product.  Our Serta toppers don't have a specific warranty, but we have partnered with Amazon to replace the product or refund your purchase if you are not happy with the performance.

**Q: Why is this $100 but the same model  at kohls $400?**
A: I just got the one sold at Kohls after returning this one.  On sale from $400 for $174 online.   This isn’t the same product.  The Khols mattress topper is much heavier, comes with a cover and the packaging was much better.

**Q: i sleep cold, will this keep me warm?**
A: Actually, just received ours 2 days ago. I slept on it last night. It was very comfortable and my back never felt better but it was HOT! I sleep cold too.

**Q: Is this certipur-us certified?**
A: yes. All Serta products certipur-us certified. Check this link  https://www.serta.com/standards
