[This review was collected as part of a promotion.] I received the SERTA PERFECT SLEEPER Cobalt Calm 14.5" FIRM PT a few weeks ago. I was a little concerned that it might be too firm but I can't sleep well on softer mattresses so I wanted to give it a try. Let me just say, I haven't slept better and I can't wait to crawl back in bed! It's firm but not hard. I have bad hips and this has even helped my hips to not feel sore in the morning after sleeping on my side all night. It stay cool throughout the whole night. That's big for me because I'ma very hot sleeper. I also love the fact it's anti microbial, so it will start feeling and smelling fresh longer than a typical mattress. Well done!

[This review was collected as part of a promotion.] I received my mattress a few days ago, and let's say it's an excellent mattress for my backache and desk hernia issues. It's very thick and rigid that it feels you are sleeping on the clouds or being carried. I have never felt this comfortable sleeping.

After three nights, my wife and I both are adjusting to the feel and comfort offered by this mattress. We switched from a “foam “ type mattress to this inner spring type and are glad we did. Hopefully it will maintain its shape and firmness longer than our previous mattress.

[This review was collected as part of a promotion.] I got this bed and was so excited to start using it. I have pain in my lower back and this mattress is magic! It's super thick and comfortable. I enjoy that when my significant other gets up, it doesn't wake me up. Great quality.

[This review was collected as part of a promotion.] My current mattress is at least 15 years old and it makes my back pain getting worse. I'm glad that I got this Serta mattress and I can tell my back pain reduces rapidly after the first week. The most notable difference from this mattress is the blue color. But since I use a mattress cover, it doesn't make a big deal. However, even if you dont use any cover, blue is a good choice because it helps to hide stain or any remark really well, thus the mattres always looks clean and neat. By the way, the mattress is firm and very well made. The surface is covered with CoolFeel fabric so I can feel the chill as soon as I lye down. I guess that may be a factor to help my back pain getting better. It also helps me to sleep better, especially during any heat wave days. Now I do believe the saying that you can have a good sleep in a good mattress.

I wake up feeling refreshed!

[This review was collected as part of a promotion.] I have been sleeping on this mattress now for a couple nights. It's amazing what a good mattress does for your back. All of my sheets seem to stay on it overnight. It is the perfect depth and has great comfort for my husband. He was not wanting to get up this morning. I think I will be upgrading all of my bedrooms to this mattress.

[This review was collected as part of a promotion.] I recieved the serta perfect sleeper firm mattress to try in exchange for my honest review. This mattress is firm and gave me the best sleep i have had. You dont sink into it. Helps my back really good. The mattress is 14.5 inches thick.

[This review was collected as part of a promotion.] This is an amazing mattress! The extra pillow top is where the manic is at. I seriously might upgrade to a king just because it is that comfortable! Serta is an amazing brand that goes above and beyond for their customer.

[This review was collected as part of a promotion.] This is a fantastic mattress, and I know exactly why it is named “Perfect Sleeper”. Since sleeping on this new mattress, I have had some of the best sleep I've ever had. The mattress is the perfect combination of softness and firmness. The thick, plush pillow top feels like a comfy cloud but with the firm support, my body doesn't sink and is gently supported from all angles. The mattress has a nice cooling aspect and doesn't make me feel too warm. Fabric is sleek and smooth as well. Even the color scheme and design on this mattress look high end and it's a shame it gets covered with a sheet. Sleeping on the Serra Perfect Sleeper, I have never woken up stiff or sore. Mattress height is quite high, at 14 inches so it is important to note that some sheets won't fit all the way around and I needed to use deep pocket sheets. This is a quality made mattress with a lot of advanced comfort features. I am very happy with it.
