We have had our mattress a little over 6 months and the top half where we lay our heads has already flattened more than the rest of the mattress. It's already lopsided as well. For the money we paid this should be in brand new too top shape.

Proud to support a company manufacturing in the USA. We are six weeks in with sleeping on our new queen cobalt calm medium mattress and have no complaints. Both of were comfortable from day one.

My husband and I love it because it sleeps so much better than our old firm mattress. The height of the mattress is high with the box springs, but easy to make up in the mornings because I don't have to bend my back very much. Great purchase!

I was sinking into my old mattress and therefore tossing and turning through the night. My medium Cobalt Calm mattress was the answer to a deep restful sleep that I have not experienced for some time. Very pleased.

It's good for what it is I suppose, but the top layer of memory foam is not doing my back any good. At this point, I intend to return it when my 30 day trial period soon ends. I will never purchase any kind of memory foam mattress again.

We chased down this specific mattress to get as close to the same model that we purchased 15 years ago. We will keep coming back to Serra and this particular mattress every time!

The bed is a perfect fit for my bed frame. Super comfortable and soft but would probably like it a smidge firmer just not totally firm. Overall it's a great bed.

My husband and I have just about opposite needs when it comes to a mattress and this is perfect for us!! Firm with a soft pillow top. We are both sleeping very well.

Supportive, comfy, do not sink down and disappear into the abyss of memory foam. We are very happy with our purchase and look forward to more time on it. 🙃

We tried this mattress out in the store, loved the feel. When we got it delivered, my wife and I both said this ain't as firm as the one in the store was. A little disappointing but decent mattress overall
