Bad packaging
The mattress arrived in a shipping box with plastic wrap covering only the center, forming a roll, and the edges were discolored. While it's unclear if I received a used mattress, it is unacceptable to sell a hygienic product without proper packaging and sealing—such as in a dirt- and water-proof bag.

3-inch foam mattress cover
We actually loved this but found it was actually too firm so we selected another type of cover.

Do not buy
It’s pretty firm, not soft or cloud-like. The smell is horrible. I have taken the sheets off every day for the past week and opened my window in hopes that it would air out, but no. Every night I sleep inhaling the plastic-y smell. Would not recommend.

Unusable
The topper will not flatten out and remains twisted as it came.

Great memory foam topper for extra firm matress.
Excellent memory foam mattress. Just bought an extra firm mattress set and needed something softer for my back. Love this it’s perfect. 2” wasn’t quite thick enough.

Will Return
Haven’t slept on it yet, but there is a stain on one side and it has a crease it in that will not go away. It also seems to run short.

Better sleep
[This review was collected as part of a promotion.] I recently received this product and started using it for the first time. I think this is a really good product if you are looking for something to make your bed more comfortable. I love this and have slept better since I received it.

Wonderful for Sofa Beds
[This review was collected as part of a promotion.] I got this mattress topper for our guest room sofa bed because the original mattress was too springy and uncomfortable. Once I added this topper it was a game changer for my guests comfort level. Everyone slept so much better.

What pain!
[This review was collected as part of a promotion.] I cannot say enough good things about the topper. Before I go on about everything I love about it. I'll start with issues that someone might find troublesome. Firstly, you have to be careful when opening the topper. It goes without saying, however, it's possible you might open it and see tears. I opened the topper and noticed in a section where it was wrapped, a tear had occurred. Not an issue for me though. Secondly, it will stink for a few days. Lastly, do not place sheets with prints on the topper because it will transfer. Didn't realize this could happen, but discovered it when I was changing the bed sheets. Now the topper has imprints of the images from the sheets. I found it funny and it doesn't bother me. Now for the good stuff. It's super soft! It has changed everything for me. The mattress I have started to feel rough and I was waking up in pain. Not anymore. Since I started using the topper I no longer have that issue. The issue I do have is mustering the energy to get out of bed because I'm comfortable. It hasn't lost its shape yet either! I've been enjoying it.

Copper 3” full topper
[This review was collected as part of a promotion.] I was sent this product to try. I really haven’t “used” it yet as it’s on our guest bed and we haven’t had guest since adding it to the mattress. The feel of the thickness of the product is nice so I’m sure it will add extra comfort.

So comfortable
[This review was collected as part of a promotion.] I got the Copper 3" Topper in size king about six weeks ago and it has brought new life to my older mattress. Ive been sleeping better and waking up feeling much more energized than i did before. I love my new Copper Topper and encourage anyone to try one out.

Good nights rest
[This review was collected as part of a promotion.] I was kinda shocked by the weight of this when it came. pretty easy to unroll. It did take a few hours for the shape to calm down and lay flat.Even though I just got a new mattress it hasn't been very comfortable. I love how it really shapes to your body in a good way.

Love this topper
[This review was collected as part of a promotion.] We had a 4 inch topper on our mattress and it just was too soft. So I got this 3 inch Copper Topper and we absolutely love it. It is firm but cradles our body perfectly. I wake up feeling so much more rested and my body feels amazing. My hips usually hurt if I sleep on my side. Not with this topper. I'm sleeping more comfortable than ever on my back and my sides. It's a firm topper, but in a good way. It came rolled up nice and tightly in a decent sized box. But once unpacked, it unrolled and fluffed up quickly.

Nice mattress
[This review was collected as part of a promotion.] I got this a few weeks ago. I set it up so it could expand for a few days while I was out of town. Came home it was fully expanded and is so comfortable to sleep on. I definitely would recommend this mattress

First time
[This review was collected as part of a promotion.] This was my first time using a topper and I have to say it is pretty awesome. It came in a box and was so easy to unwrap. I left it on top of the mattress for the entire day and it really opened up to the full queen size and was a perfect fit. After getting the bed together and going to sleep it was great. I felt well rested and refreshed. It has added more support and the memory foam is really nice and conforming to my body. I have really enjoyed sleeping on this and have loved the improvement it has provided to my bed.

Love it
[This review was collected as part of a promotion.] Wow! What a difference the Copper RX 3" Topper King has made for my sleep! I am no longer in pain every morning even though my mattress was pretty new. After going through many toppers in the past, I highly recommend this topper.

So comfy!
[This review was collected as part of a promotion.] I’ve never had one of these but really wanted one so I’m happy I was finally about to try one and let me tell you it’s so comfy! At first I thought it felt weird and strange when I went to lay down to sleep but that’s because I’m not used to it. I can say that when I’m laying in the middle of the bed it feels like I’m leaning to one side? I don’t really understand that. So I just sleep towards the side

Sleeping on a cloud
[This review was collected as part of a promotion.] I was excited to try the Copper Rx topper on my full bed. My initial impression was that it smelled. I am happy to report that disappeared quickly. When I placed it on the bed I found it did not completely cover the mattress leaving a small border area uncovered. It did not have corner straps to hold it the mattress so there is a bit of shifting. All in all it does improve the comfort of my sleep.
