Review: Ordered a mattress in a box and found it had good support, but FAR too firm so we ordered this topper. In so glad we did! It's like sleeping on a cloud! The best sleep I've had in a close to a decade!
Review: EXACTLY what i wanted. My family bought me a similar Serta topper 5 yrs ago after a major surgery. My matress has seen better days. The first one was very comfortable and I was still using it but my large dog digs at the bed before laying down and did rip it. Honestly, the first one was a little too soft. I had a full open abdominal so those muscles were cut and I have bad joints , so sitting up can be tricky. I found you sink in and had to actually roll to get up. This Serta topper is much more comfortable & much easier to get up from because all though soft, it is firmer. It bounces right back after you get up. . It gives but doesn't make you sink. This helps sleeping when you have joint pain. I didnt feel as hot with it as much as the first either but could just be me. It came in a solid box ,( grandkids LOVE the box with the sheep and large flaps lol) compressed, well wrapped and in a duffle bag. It was fully expanded as soon as I opened it. I didnt notice any smells. This was the best sleep I've had in a long time and at this price I've considered buying an extra when it inevitably rips and wears down but I've read some reviews online that toppers didn't fully expanded after stored a long time. Ill just enjoy this till it dies and replace it then. It was very fast shipping also. I HIGHLY RECOMMEND THIS & WILL buy again!

## 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
