4.5 it is very comfortable, plush and thick. And it comes with a cover. I put it in my guest room and they could tell difference. Would definitely buy in the future and its thick enough on my mattress that you have to buy deep sheets but worth it.

Super soft 4" pillow-top gel memory foam topper. We got this for our son's bed and it has made a huge difference in his sleep. The first night he slept on it he commented "I slept the best ever!" It is so soft and comfortable. The topper seems to be good quality and feels so smooth and comfy. Definitely recommend. Getting more for our other kids. Impressed!

Super super squishy. I guess we just don’t like a super squishy bed. We are in our 30s but more squish actually means more pain. The beds that are great are the ones that can mold to your shape while still giving support and firmness. This is just way too much squish with no amount of hold. Might work for someone looking for that though . Came vacuum sealed for the blue mat and then had a kind of pillowy sheet cover come with it too

We got this topper for our son's mattress which has always seemed uncomfortable. This is just what it needed. He's a hot sleeper so cooling feature was important, so far so good according to him. It arrived packaged efficiently and was easy to get it ready for use.

We were cautiously optimistic when we unboxed this topper—it came flattened (as expected) and included a nice cover, which was a bonus. After letting it expand and putting it on the bed, we looked at each other like, “Well…we’ll see.” Three nights later, there’s nothing left to question. We’ve both been sleeping great—my husband’s snoring has even decreased—and our two furry companions at the end of the bed are sleeping better than ever, too. Highly recommend if you’re looking to upgrade your sleep without buying a whole new mattress!

This mattress topper is one of the best toppers i have ever slept on. The foam is super thick and durable. It's an easy set up takes little to no time at all. I would have normally woke up with backaches and with the first night of sleeping on this topper my backache was gone and i rested well. It is so worth the money.

This 4" memory foam mattress topper exceeded my expectations! We put it on an older mattress in our guest room and it instantly upgraded the comfort level. I only slept on it one night to test it out but I slept great. No complaints. It’s incredibly soft and squishy and has that wonderful sink in feeling without it being too much. I love that there are no added flame retardants and the machine washable cover is a huge plus. We have a thick mattress and the cover fit over it well. The topper also adds a bit of height to the bed, which makes it feel luxurious. Unboxing was very cool! Once you cut the plastic, it expands quickly and takes perfect shape. Highly recommend if you’re looking to revive an old mattress or add some serious comfort!

This plush memory foam topper adds an extra measure of comfortability. It’s made of a high quality foam and comes with a cover that has deep pockets to secure the topper to your mattress! My only suggestion is making sure you have deep pocket sheets as well.

This foam mattress topper is so comfortable. If you love a soft mattress this is heavenly! Fits a full size mattress perfectly with zero overhang. The plush thick cover has deep pockets so it never pops off the corners. Made my mattress feel like im sleeping on clouds! This foam topper is 100% certiPUR-US certified which brings me peace of mind sleeping on it every night.

I'm using this memory foam topper on my queen size guest bed. It's 3 inches thick, blue, and so cushiony! After opening the package the foam topper practically rolled itself out onto the bed and expanded instantly. The fabric cover is also cushiony, I might be sleeping in the guest room tonight lol
