This mattress topper is a life saver!! I bought a new mattress that was way to firm. I bought this mattress topper and it has made my bed amazingly comfortable! Soft, cozy and not saggy or hard to change positions on. I am not tossing and turning to get comfortable. It shapes to your every move like a hug from a cloud. I absolutely love it and I will be purchasing a couple more for the other beds in the house! When I unpackaged and rolled it out it filled out right away. I took someone elses great advice and opened it on the bed. I cant believe it fit into that box! I would reccomend having deep pocket sheets. I put a mattress protector over everything and the sheets stay on with no problem. It is a true 3" thick unlike cheapies I have tried. I have a bad back and hips. I feel like a new person! Did I forget to mention I love it?

Saved my back and saved me $$

[This review was collected as part of a promotion.] First off, this comes packaged so small! I highly suggest opening on your bed so you don't have to move once expanded. It fluffed up to about 3" rather quickly once removing plastic. I noticed no smell. Fits great on my bed. Its amazingly comfortable,  you literally sink into it and it  conforms around perfectly. I sleep great on this and wake up very refreshed!

Very comfortable

influenster.com

[This review was collected as part of a promotion.] This mattress topper is overall a great value. It helps keep you cool at night while providing comfort and support. I used to wake up every morning with back problems, but since using this, they have stopped. The material is super spongy and durable.

Excellent Mattress Topper

[This review was collected as part of a promotion.] I was so excited to try CopperCool’s Memory Foam Mattress Topper and WOW! did I not expect how comfortable it actually is! I have been having such bad back pain recently due to our current mattress being old and unable to replace at the moment. Of course whenever I got my mattress years ago I never thought a pillow top would be an issue but it is. Now that my husband and I have used it over the years, it’s creating divots on both our sides and not supporting our backs. We’ve been using our new memory foam mattress topper for about a week and a half now and we don’t remember when the last time we slept this good! The other important feature we look for in a bed or mattress topper, other than the comfort level, is the coolness. Especially now in the summer months, we tend to have night sweats more often but we haven’t had ONE since trying our new topper. I would think because the mattress topper is thick that it would also be hot but that couldn’t be further from the truth. I cannot say enough good things about our new CopperCool mattress topper, I would recommend this to anyone and everyone that’s looking for support, comfort, and breathability in a new topper.

This saved my back & is keeping me cool during the

[This review was collected as part of a promotion.] We’ve finally found the secret to better sleep—the Copper Cool 3" Memory Foam Topper. From the moment we unboxed it, we could tell it was going to change the way we sleep. The topper instantly transformed the bed, making it so much softer and more inviting.

He says, “It feels like I'm sleeping on a cloud now. I knock out so fast and sleep like a baby!” And it’s true—no more tossing and turning or waking up with a sore back.

The copper-infused cooling tech is a total game changer, too. It helps regulate body temperature, which is perfect for hot sleepers. The foam contours just enough to support pressure points without that “sinking in too far” feeling.

Turn your bed into a cloud with the Copper Cool 3"

[This review was collected as part of a promotion.] Very soft and cushy mattress topper. It's very breathable and feels really cool against the hot summer. It's easy and lightweight to move and feel very durable.

Soft and cool

[This review was collected as part of a promotion.] I am still trying to get comfortable with it while sleeping, but have noticed that the comfort is getting better and my sleep alpha is improving too. It does take some time getting used to, but once you overcome that, it should be worth your time.

Restful Results!

[This review was collected as part of a promotion.] Before the review I should mention that I have always used a mattress topper on my beds, and this one is a very comfortable and useful topper. It’s extremely plush and I sink into it making it conform to my body perfectly. My only knock is its claim of being a cooling topper. I run very hot at night so I was excited to get a product that helps me not sweat throughout the night and keeps my body temp regulated. I used a very light fitted sheet with this topper and it works great (I would recommend getting a deep pocket set of sheets if you are new to the mattress topper game). But on my first few nights of use I didn’t notice a difference when it came to my temperature throughout the night. I still got a very comfortable nights sleep with the topper as opposed to just my standard mattress, but I wished it gave me more of a cooling sensation. It’s still a great topper and a deal for the price and I would recommend it to anyone who is in the market for an upgrade to their standard mattress, but I would keep looking if the cooling factor is very important to you.

Comfortable but not very cooling

[This review was collected as part of a promotion.] I used this topper under a papasan cushion and cut it to fit. It seems to be good - although it seems to be flattening out something without popping back up like it did at first.

Decent topper

My main reason for buying a 3in memory foam topper was because I mainly sleep on my right side and my shoulder had been sore in the morning.  I've already had surgery on it so I didn't want to get another.  The cooling feature was just going to be an added bonus. Unfortunately,  I have been hot, not cool since using it but it's pretty comfy for my shoulder so I figured 3 stars would be fair. Plus I  couldn't be mad at the price for a King size. My dog disagrees! I may need to build a pit bull step lol
