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: Doesn't seem to run hot! - Package arrived on time and was well packed. We removed it from paking and removed shipping plastic, then allowed it expand per the instructions. It had no offensive odor at all; in fact it was a pleasant smell if anything. The next day we placed it onto our mattress (it was easy to placeand it stays in place well), put the sheets on, and at bedtime we climbed in. The topper provided an excellent mixture of softness and support. It has not run hot at night and is very pleasant to sleep upon. It appears to be a very durable topper. ## Features - Breathable gel infused memory foam engineered for comfort and support - ThermaGel particles help provide a cool, comfortable sleep surface - Adapts and conforms to the individual contours of the body to provide enhanced support and comfort - Enhances the sleep surface and extends the life of your mattress - Made in the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0889898S8 | | Age Range Description | Adult | | Best Sellers Rank | #75,180 in Home ( See Top 100 in Home ) #82 in Fiber Beds | | Brand | Serta | | Brand Name | Serta | | Closure Type | Blue | | Closure type | Blue | | Color | Blue | | Colour | Blue | | Customer Reviews | 4.3 out of 5 stars 3,001 Reviews | | Fabric Type | 100% Memory Foam | | Included Components | ThermaGel Memory Foam Mattress Topper | | Item Display Dimensions | 7.6 centimeters | | Item Firmness Description | Soft | | Item Type Name | Serta ThermaGel Memory Foam Mattress Topper | | Manufacturer | Elite Comfort Solutions | | Manufacturer Part Number | 12275 | | Material Type | Memory Foam | | Model Name | ThermaGel | | Model Number | 12275 | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | Breathable | | Product Care Instructions | Machine Wash | | Size | King | | Special features | Breathable | | UPC | 094325278879 | | Unit Count | 1.0 Count | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Serta - **Colour:** Blue - **Fabric Type:** 100% Memory Foam - **Size:** King - **Special features:** Breathable ## Images ![ThermaGel Memory Foam Mattress Topper, King, Blue | 3 inch king gel memory foam mattress topper, ThermaGel cooling, deep pressure relief, CertiPUR-US certified - Image 1](https://m.media-amazon.com/images/I/919fn1VWB+L.jpg) ## 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.

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! ## Frequently Bought Together - Serta ThermaGel Cooling, Pressure-Relieving Memory Foam Mattress Topper, 3 Inch, King,Blue - SafeRest 100% Waterproof King Size Mattress Protector - Fitted with Stretchable Pockets - Machine Washable Cotton Mattress Cover for Bed - EASELAND King Size Mattress Pad Pillow Top Mattress Cover Quilted Fitted Mattress Protector Cotton 8-21" Deep Pocket Cooling Topper (78x80 Inches, White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/263473838-thermagel-memory-foam-mattress-topper-king-blue-3-inch-king](https://www.desertcart.sn/products/263473838-thermagel-memory-foam-mattress-topper-king-blue-3-inch-king) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-29*
