This is a wonderful memory foam mattress topper with a very nice soft cover, and I couldn't be happier with it. This mattress topper has truly transformed my sleeping experience. I was getting ready to replace my old mattress but now it feels like a new bed.

1) The thickness of this mattress topper is a game-changer. It provides an extra layer of comfort and support that has made a noticeable difference in the quality of my sleep. I no longer wake up with aches and pains, and I feel more rested and rejuvenated each morning.

2) The cooling feature is another standout aspect of this mattress topper. I often struggled with overheating during the night. However, this mattress topper's cooling technology has kept me comfortable and cool throughout the night, which has greatly improved my sleep quality.

3) The soft cover is a delightful bonus. It's incredibly plush and feels luxurious under my sheets. It also adds a layer of protection to the mattress topper itself, making it easy to keep clean and maintain. The grippy nubs on the bottom keep it in place.

Overall, I highly recommend this mattress. It has transformed my sleep quality, and I wake up feeling more refreshed and comfortable than ever before. If you're looking for a way to upgrade your sleep experience, this mattress topper is an excellent choice.

Fantastic mattress topper

Im not going to give this product less than 5 stars because its not fair. People seem to like it. I however returned it as soon as I opened it because I could tell it wasnt what I needed. I bought a Zinnius mattress topper from Sams ages ago got rid of it after I had surgery cause i couldnt climb into my bed. Foolish because now I have MS and I am hot ALL the time and that mattress topper was cooling as soon as you sat on it no matter what  sheets you had on it. The foam was a blue color with a layer of beige at the top which was the cooling effect. It looked this way in the reviews so I ordered it but after it arrived and i opened it, the material was a light blue with white swirls and it didnt even feel the same so i returned it.

Not 5 stars for me.

This mattress topper is TALL but the memory foam quality is excellent. It truly has a cooling effect on the top and a textured bottom to help grip the mattress underneath it. My husband and I both have slept great on it, although we have had to increase the firmness of our mattress underneath so that we don’t feel too sunken in.

Wow. Perfectly squishy mattress topper.

This is a great topper if you want a super soft and fluffy bed. With this topper I felt like I was sleeping on a cloud. The way you slowly sink into it as you lay down was very comforting. It has gripping nubs on the bottom side to keeping from sliding around. It is just the right size to cover the whole bed without overlapping. Still fits under my sheets without any hassle.

A super soft mattress topper

We bought our mattress four or five years ago from a big box furniture store and it's not holding its shape. We were getting ready to shop for a new mattress when we received this mattress topper.  The topper has made a huge difference in our sleep quality. We like it so much that we're no longer considering purchasing a new mattress. The memory foam gives your back the support you need to get a good night's sleep. Both my wife and I sleep on our backs and on our sides with no issues.  I really don't have any complaints. There is a bit of a smell when you first get it, but if you follow the instructions about letting it air out for one to two days prior to putting it on your mattress, there are no issues.

Amazing!

I cannot say enough good things about this mattress topper. This topper provides amazing cushion. It provides balance and support as you sleep. You feel like it forms to you for the best night sleep. It also keeps it shape well.

Great sleep

Shipping was excellent! Only problem, after only a couple weeks use, it’s beginning to sag in the middle and I’m an older woman, 128 pounds, 5’ tall.  I don’t think this should happen.

Sagging Middle

Nice and thick. The softness seems plush. If you like firm mattress, this is not for you. However if you like plush support, it feels comfortable when I lay on it. It also feels cooler than my mattress.

Nice and thick but soft mattress topper

When I lay on it, it swallows me up . I think I need a firmer type mattress . This surrounds me and does not feel cool (keeps me hot). Almost difficult to get out of bed because how much you sink in. I'm not saying it's a bad product, it's just not right for me.

Like quicksand.

If you are looking for support, this is not the topper for you. It is very very soft and you sink down. It is also extremely HOT. You will sweat.
