I am very pleased with this 3-inch memory foam mattress topper. It added an extra layer of comfort to my bed and made a noticeable difference in the quality of my sleep. The memory foam is soft and supportive, contouring nicely to my body while relieving pressure points. It hasn't gotten really hot yet, so I can't address the cooling feature. The topper expanded quickly after unpacking and fit my mattress perfectly. It feels plush without being too soft, providing the right balance of comfort and support. Since using it, I've been waking up feeling more rested and comfortable. Overall, this is an excellent mattress topper for anyone looking to upgrade their bed without purchasing a new mattress. Highly recommended for its comfort, quality, and value.

Update#2: Customer Service is phenomenal. I reached out with pictures of what was going on and they went above and beyond to help me and make it a hassle free fix. Based on this experience I would buy again. Update:Still comfy however it is getting tears everywhere which is insane. There is some kind of problem. I have no clue how long it's going to last. I will reach out to the company to see if it's a defect or what is going on and update. This is hands down one of the thickest densest yet soft cradling topper I've ever purchased. It's firm enough that it's heavy duty. Good quality. It's got some holes to let air come through so you don't overheat but it does not interfere at all with the mattress pad's ability to stay solid. It's amazing! Considering the price point, I was afraid that I'd be getting something really crappy. I would absolutely purchase this again. Bonus if you happen to have a padded mattress cover it would make this thing feel like a cloud. The topper on its own is phenomenal if you throw on a cheap plush mattress topper incredible.

I bought this for the 3/4 bed in my camper. It sure makes a difference in comfort level. It is just slightly big for the width, but not enough to be unusable, and a whole lot easier and cheaper than searching for a hard to find 3/4 RV mattress. I also bought a sort of shredded foam topper to go on top and between the 2, I am sleeping in greater comfort. I bought a duvet cover and put both of them inside to keep them clean.

After 1 night, this mattress topper is amazing. I didn’t wake up hurting because I was fully supported!! Game changer for sure! I opened it and let it sit out for 2-3 hours and it was fully expanded. A light smell , but went away. Great back, hip, and overall joint support. Super easy to set up. I was comfortable all night and never got hot.

It’s a nice mattress topper. I got the 2 inch thick padding and it was alright, Kind of stiff at first but then it squishes down and is comfortable. It didn’t have any type of smells or anything and it fit my bed decently. It might be slightly overpriced but nothing horrible.

The most practical purchase I've made so far this year! I was ready to buy a whole new mattress, but decided to try this topper first. I have a very firm hybrid (spring coil and memory foam) mattress that was starting to take its toll on my body after 6 years. I need something plush that will cradle me. This topper was the solution. I have a twin bed and I got this 2 inch topper. I'm 128 lbs and the 2 inch topper is thick enough for me. The width of the topper is almost as wide as my mattress, just slightly narrower. The length is perfect. The topper fluffed up within minutes. Mine came folded in half, so I was worried about the fold down the center, but it was gone when the topper fluffed up and you'd never know it was ever folded in half. I've slept so good on this and it hasnt made me too hot either! I wake up feeling refreshed and pain-free. Even if this only lasts a year, so what? It was only 20.

Amazing topper, just buy it. Great value for the money. Took about 30 ish minutes to fully fluff up after opening. No odor or smell from it. Very comfortable and super supportive in any position.

Feels great and has a nice give when you sleep. It does tend to slide around in the center as there is no middle strap to secure to the mattress. I have not had any of the corners come undone though. The thickness of the pad is true to size. I did find a slight odor upon first opening the package, but it faded within a few days. Overall the product does as described and I have been sleeping good on it!
