Serta 3" Cooling Coppergel Memory Foam Mattress Topper, California King

This is a great memory foam topper. It was shipped in a Serta box and came in a Serta bag. This is quality memory foam with a little support. It takes awhile to expand so dont pull it apart. Let it expand on its own. I highly recommend!

When I took it out of the box I looked at it and thought, this will be going back for sure. I decided to do as the instructions suggested before totally writing it off as a bad purchase. I let it sit overnight and when I checked it the next morning it was perfect. I was very surprised. It is nice and thick and it responded as most memory foam, it forms to your body. As for my arthritis, well I still feel soreness when I am on my side even with this topper but I don't think many mattress/toppers will totally eliminate that. So if you order one, don't judge it by how it looks when you take it out of the box, do as instructed and check it the next day.

I love the Cooling, Antimicrobial Memory Foam Mattress Topper, CopperGel Infused 3" Queen. This foam mattress topper really does cool me down at night. The thick memory foam conforms to my body and gives me a better nights sleep. I am very happy with this product and the cooling end results.

But a new good name, brand hybrid bed, which was slightly too firm and this mattress topper made it perfect. It's not too mushy. It's just right for my comfort and the whole thing is still firm but soft.

Very comfortable and thick! We sleep great now.

Mattress was way to soft. This topper was just what I needed. Much firmer.

This Serta mattress topper is great! We tried it out on a queen air mattress we had to use. It was slightly larger than our queen air mattress and hung over the edges. Upon taking it out of the box, it is extremely compressed. The instructions say to let it expand over 24-48 hours. We didn't have that long, so I found a trick: gently shake the topper from various sides and gently stretch. It expanded within 20 minutes! Deep pocket sheets fit fine, and we even had a mattress pad on, too. Unlike other toppers, this one did not have any weird odor!

First of all I'm glad we got to try this in the winter first before the summer, because I slept pretty warm. Makes me worry about the summer coming up though. We might have to remove it. It wasn't very cooling, but all we had was a sheet on it, not mattress protector. Both me and my boyfriend are warm sleepers, just so you know. This might work for you if you have a hard bed. It does make our bed softer. I can sleep on my side better with this topper (female/hips) but not other positions. My boyfriend can sleep better on his back. It's a little short, which I thought was weird (see photo) We got a new mattress cover and we'll try it with that over the foam topper to see if it fixes the warm factor.

The way that it's shrink wrapped, I'm not sure if it caused the foam to be deformed on the edges, or if they cut the foam after it was wrapped. But the edges and sides are deformed. They claim it's a cool gel foam, but it's just foam so it's sleeps hot just like sleeping on foam.

The worst product that I have ever bought it doesn't fit and it looks like it was cut by a 5yr old very disappointed in this product and that's supposed to be a queen
