It is as advertised and it puffs up to the full 4" as advertised and does come with a zippered cover which is nice, but it does move on the bed somewhat because it's a mattress cover, not a mattress pad. It is fairly easy to adjust, just pull it back where you want it every few days. It is comfortable and you sink into it as it cradles your body. As others stated in their reviews is that it does smell at first, but the smell does dissipate. If you can leave it uncovered for a few days before use, it will help with the smell greatly. I didn't have that option, so I just unzipped it most of the way the first couple of days and it helped a lot.

Bought the twin XL for my daughter’s dorm room. She said it’s so comfortable. The mattress topper that comes with it is not waterproof so I bought another waterproof mattress pad to make sure the memory foam was protected, then put the mattress topper over both. A little extra protection, may not be needed if you don’t care about protecting the memory foam, but the pockets on the topper were deep and covered everything no problem.

We bought this mattress topper to add some comfort for our RV queen size mattress. Had only mild foam odor when opened… the smell dissipated after one day of leaving the windows open. The to[per is fairly soft and added Great Comfort to our existing mattress. I would highly recommend!

I purchased this mattress topper for my parents and they love it. My Mom has back problems due to a car accident and she hasn't had any major pain since she's been sleeping on the topper. If you're considering this mattress topper, you should definitely give it a try!

Its actually pretty good. Im happy I bought it. I have my grandmother's handmade really thick and heavy quilt on top of the topper but it has made such a difference. Because of the added topper i dont have any more pain. Its thick and heavy and white and clean and cool. I pretty much love it. I was in the market to get a whole new mattress and i needed to wait a few months before getting the mattress so this was a perfect addition to my current old worn out mattress. Ill still get a new mattress in a few months but so far its been a few weeks and its still holding up greatly. Im very satisfied. Thank you

This product is always our ‘go to’. It has improved since we last bought one! We never thought it needed improving but the cloud I am sleeping on now is the softest, coolest mattress topper & memory foam combination ever!!! My husband and I love our bed again!

I bought a twin size for our pull out guest bed our daughter tried it out and liked it so much we bought one for her full bed. She loves it and really likes the cover that comes with it. We have had both for a month or less so can't answer how they will hold up over time.

I loved everything about this topper except for the smell. It took about 8 or 9 days for the smell from the foam to dissipate. I aired it for a day and wished I had aired it for a week. The smell is like a chemical smell. I have a sore shoulder, unfortunately, the one I have to sleep on and bursitis in my hips. It does help with that. The cover went on easily and zipped with no problems. I would buy another one, but would definitely air it out a good week before using it.

Even though my mattress is decent quality and fairly new, I just couldn’t get the “cocoon” feel that I sleep best in. Now I climb in, and sink into a dreamy cushiony, yet supportive surface. The combination of foam and top layer padding makes the bed comfortable and welcoming. Make sure you find super deep pocket sheets to fit over the extended thickness.

This is the second mattress topper I have owned. The first one had body; supported and hugged my back. I would awake and feel refreshed. I have slept on this topper for one week and so far I am not happy with it. It is too soft and not supporting my body. Now I wake up with an aching body. I was looking for a topper to hug and support my body.
