We have a medium firmness bed and wanted a little more softness without going too far. This seems to be just about right for our comfort presences. It is pretty soft but still feels supportive. We haven't experienced being too hot, but we have not owned during summertime yet.

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.

Soft and very comfortable to lay on. The quality of sleep has improved significantly since I added the mattress pad. I suffer from fibromyalgia and definitely notice how the pad cradles me.

I’m overall pretty happy with my purchase, especially for the price. However, when it first comes out of the bag it wreaks of fish. You have to let it air out. I let it air out in my living room for a couple of hours, flipped it, and sprayed it with febreze odor remover and it got rid of the smell. As for comfort, this has helped my back pain/sciatica a ton compared to sleeping on just my mattress with no topper. It’s worth noting it is definitely one of those that traps heat. Luckily, I’m not a super hot sleeper and I crank the A/C when I sleep, but if you sleep hot/sweat when you sleep, this is probably not for you.

4 inch is okay if your not worried about getting in and out of bed. It is very high. My husband being 5'4 had a very hard time. Also I found it comfortable but since you sink it I can imagine how hot it would be especially in the summer.

My wife and I both love this topper. We are using it on an RV Murphy bed mattress which is uncomfortable until this topper is used. We actually love it so much we will look and see if they make a king size we can use on our bed at home.
