For me it was extremely uncomfortable felt like just a piece of regular foam. If you like to sink into a piece of foam it would work really well for you. I am sure it is a good product but didn’t work for me.

I was having back issues and hoped this would help. Not only has my back pain disappeared but I am sleeping great! This mattress topper is wonderful! Even my teenagers love it!

When we first receives our topper, we put the foam into the cover and zipped it up and the zipper pull came right off the end. It had not been sewn at the end. I contacted Serta and they immediately sent out a new cover. Great customer service.

This topper is like great. It added enough padding to the top of the camper mattress so that it wasn't hard anymore and was very comfortable to lay on.

I have back problems and was hoping the Serra pillow topper would assist as my mattress is so firm and uncomfortable but I didn’t notice a difference so ended up returning this product.

My mattress was a little too firm for me. I didn’t want to buy a whole new one so I bought this 4 inch memory foam topper. I sleep so much better without the aches and pains in the morning.

Our 1 year old Casper mattress is too hard for us and we were on the verge of throwing it out. Replaced a 2" topper we had before and this made all the difference. Saved us from buying a new mattress up to now.

Bought this last month to spruce up our not so comfortable guest bed. So far we’ve had 2 visitors stay over and they both slept great. I like that the cover is removable for washing. It’s a good buy.

Omg! This was worth every scent that I paid. I had broken my back a few years back, it is like sleeping on a cloud. This is the perfect pillow topper around! My only complaint, is that my eldest cat, has a hard time to get up onto the bed.

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.
