Rated 5 out of 5 by from So comfortable [This review was collected as part of a promotion.] I got this PS23 SERTA Mattress for me i needed something different and comfortable that wasn't going to hurt my back. I have back problems already so i needed something that wasnt hard and going to make it worse. This serta mattress is the most comfortable mattress i have ever slept on. I sink right into it and stay asleep longer. No tossing or turning at all. It has stayed pretty nice so far no fading or snagging and the mattress bounces back after getting up so it don't leave in imprint where you sleep. It's the best mattress for anybody who wants to sleep comfortable.

Rated 5 out of 5 by from Max comfort! [This review was collected as part of a promotion.] My husband and I love the Serta Perfect Sleeper mattress. It’s quite plush, cozy, so comfortable and we wake up refreshed. I love the cool-feel material fabric. I don’t wake up sweating during the night! The mattress gives nice back support while sleeping. We put it right over the box spring and fits great! It would work with any other bed frames just fine. We did put a mattress protector over for any spills and would love keeping the mattress as long as we can. Definitely a wonderful mattress for any back or side sleeper! Very comfortable and will enjoy for many years!

Rated 5 out of 5 by from Wow wow wow ! [This review was collected as part of a promotion.] I was never the one to believe a bed could help your sleep this significantly. I have bad lower back problems but after a couple week of sleeping on my new mattress , holy cow ! I sleep longer and deeper . I toss and turn less and have so much more energy through out the day . I need a firm bed to keep my back straight . But when you go to firm , it’s uncomfortable. This one hits the perfect combination of firmness . Crazy how a mattress can change your life . I’ll never go back to any other bed . If you’re on the fence , all I can say is that you won’t be disappointed.

Rated 3 out of 5 by from Not Exactly Perfect I recently bought a new Serta mattress and it is very comfortable - well, at least one side of it is. The other side has a large lump in the center of the bed, near the edge. I'm guessing that several coils were not anchored properly and they have pushed upward and, hence the lump. I'm afraid to sleep on that side thinking that maybe that will cause others to explode. I ordered the mattress on-line so will not send it back - too darn much trouble. Just to be clear, the lump was evident as soon as the plastic covering was removed from the mattress. This is the 3rd Serta I have recently purchased and two of them are fine. To say that I am unhappy with this latest purchase is an understatement. Every night when I go to bed, as I carefully avoid the lumpy side, I am reminded of my latest expensive mistake.

Rated 5 out of 5 by from So plush [This review was collected as part of a promotion.] Ok so about me..... I have tried a few different mattress types in the past all promising good rest. I have trouble sleeping for extended time because my back and neck almost settle too much (if that makes sense) and it's hard to move after being asleep. The mattress...... When they say plush they mean plush. My body sinks into the mattress but at the same time feels supported. It cradled my youngish bones with the cloud like sleeping that didn't leave me feeling like spaghetti. Overall this is a great mattress in this price point. Very well constructed and even looks good while the sheets are in the wash. Would definitely get another for our room

Rated 5 out of 5 by from Highly recommend [This review was collected as part of a promotion.] This Serta Perfect Sleeper mattress is finally THE mattress I’ve been looking for. The mattress is so soft and plush. It forms to my body but does not lose its shape. The mattress is so comfortable and I fall asleep easily on it. There is a reason this mattress is called a perfect sleeper, This mattress is extremely soft to the touch but when you lay on it you can feel it firm up and you don't sink. The sides tend to be softer than I would love but not enough to be a problem. Each night that I have slept on it has been great to which it has been very comfortable. I would definitely recommend the mattress to anyone since it has improved my sleep and back pain.

Rated 5 out of 5 by from Sleep in Comfort [This review was collected as part of a promotion.] I finally found the PERFECT mattress. PS23 SERTA PERFECT SLEEPER Blue Lagoon Nights 13.5 MED. After sleeping on a memory foam mattress for a few years my body was always sore. SERTA PERFECT SLEEPER Blue Lagoon Nights is an innerspring mattress with wrapped coils and a foam layer. It conforms to your body to help you get a restful peaceful sleep. I could roll over on my mattress and it feels like I'm getting a massage. It's temperature regulating and the comfort level is amazing. Serta knocked it out of the park with this mattress. 2 thumbs up and HIGHLY RECOMMENDED.

Rated 5 out of 5 by from Great mattress!!! [This review was collected as part of a promotion.] I’ve always gotten plush mattress but this time around I got this extra firm mattress. At first, I was scared to at it was going to be really hard and uncomfortable to sleep. However, it wasn’t even uncomfortable at all, it was actually super comfortable. I feel like now I can get better sleep and my body feels well rested. Also, I like how quiet the mattress is when you move around it doesn’t make no noise. In addition, I like how the mattress feels fresh and has a fresh sensation. Overall, I absolutely love this mattress it was way better than I expected it to be.

Rated 5 out of 5 by from Perfect Medium Mattress [This review was collected as part of a promotion.] If there were a mattress that I would fit the a perfect medium level of firmness, it would be this mattress. It is soft enough to be comfortable and firm enough to conform to you and give you the best night's sleep possible. The quality of sleep and comfort is spectacular. This Serta Perfect Sleeper mattress is pillow soft on top, supporting me where I need support and giving me exactly the level of firmness that I search for. This is a top notch quality mattress and I has exceeded my expectations. For these reasons, I would definitely recommend this mattress.

Rated 5 out of 5 by from Well made soft pillow top with firmness [This review was collected as part of a promotion.] Serta My son tried Serta’s Perfect Sleeper mattress. This blue mattress is 15 inches high with a pillow top. He said he felt like he was on top of a mountain in a cloud. Kids! haha The topper is very soft to the touch, however, the mattress itself still gives firm support to the body. After laying in it for a few, you start to settle into it as it cradles the body. He slept without tossing and didn’t move all night. He is a stomach sleeper and loved the feel. We highly recommend this mattress for people looking for a soft mattress with a middle firmness.

Rated 1 out of 5 by from Health code violation!! I never got to lay on the they we're so toxic!!! The smell was so bad it closed my nose every time I went in the room. I opened the window and that was better, until the air would come on at night and make me start itching in the other room - carrying the dispersed toxins from the beds. The materials in these mattresses are a serious health code violation!! Certi-pur is a obviously not governed properly bc this is the 4th mattress from serta that have caused extreme upper respiratory issues, and bad allergic reactions in me - including but not limited to itchy scalp, rashes all over my body, and bad headaches.

Rated 5 out of 5 by from 10 out of 10! [This review was collected as part of a promotion.] This mattress has significantly improved my quality of sleep! I suffer from chronic lower back pain and this mattress has greatly reduced my lower back issues. I no longer wake up with back pain. I am a side sleeper and my body feels well supported, the memory foam allows my whole body to be supported. The middle of the mattress does not sag. The edges do not compress when getting in and out of bed. Excellent quality, well made. I am so happy with this mattress - a good night sleep is so valuable and this mattress has greatly improved my life! Trusted brand!

Rated 5 out of 5 by from Love it [This review was collected as part of a promotion.] So this mattress is really nice. Very thick. It's thicker than my last mattress. Does sit up higher. It's a dark blue in color which is nice so you can't see stains if it does happen. As far as sleeping on it very comfortable. It conforms to your body very well. It's plushy which I love. I actually got a very restful night's sleep with this mattress compared to my other one which is a big difference. Serta really does make great mattresses once you find the right one for you. I think I found it with this one. The picture does not do this mattress justice. Yes you can see how fluffy it is but the quality I would say is great.

Rated 5 out of 5 by from Comfortable! [This review was collected as part of a promotion.] I have back and neck issues, so I’m incredibly particular on my mattresses and pillows. This mattress ticks all the boxes. The initial couple days I was a bit sore (normal for me when I sleep in a new bed.) Now it’s like sleeping on a cloud. This mattress is soft enough that it feels cuddly, yet firm enough that it gives my back the support I need. It’s thick and good quality, the edges don’t collapse when putting weight on them. Additionally, it seems like it will hold up. My sheets fit well also, though they are the deep pocket kind. Absolutely love it!

Rated 5 out of 5 by from Perfect level of firmness, very comfortable [This review was collected as part of a promotion.] I'm very happy with the Serta Perfect Sleeper mattress. It is medium firm with a pillow top. I've found that medium firm is perfect for me, as it offers sturdy support, but is still very comfortable with the added pillow top. My partner prefers a firmer bed and I prefer a softer bed, and this mattress has been a perfect compromise for us. My partner suffers from back pain and has found this mattress to be very comfortable and supportive. On an aesthetic note, the dark cobalt shade is very pretty and the top of the mattress has a beautiful design. This is my first time trying a Serta mattress, and I cannot recommend it enough!

Rated 5 out of 5 by from We both love it! [This review was collected as part of a promotion.] We needed a new mattress and this is perfect. It fits in our budget and it is something that me and my husband both like which is very important. We both like a soft but not too soft mattress and this is something that we both agreed about. It is soft but it has a good support. Another issue that we have before is that every time I have to get up in the morning, my husband wakes up because of the bed movement. Thanks to this mattress, we don’t have that problem anymore. We can both get up anytime without waking up each other. Definitely a good mattress!

Rated 5 out of 5 by from Firm Mattress is Great Have been sleeping on this for a month and it’s perfect for me. Very firm, lots of back support, height is not too tall. The first several days the mattress had a smell but it disappeared; definitely recommend airing out the mattress (without sheets) a couple of days if possible.

Rated 5 out of 5 by from Comfy! [This review was collected as part of a promotion.] This PS23 SERTA PERFECT SLEEPER Adoring Night 10.5" FIRM is just what it says. It is wonderfully firm yet soft and cuddly. It is super comfy and I get a great night's sleep. The 825 density coils do nicely support and also seem to relieve pressure in my knees as I sleep on my side. It doesn't seem to be too hot and fits most sheets since it is a normal thickness of a mattress. I do not feel my husband move nor does he when I move during the night. It is light enough to be able to flip and move as needed to keep the mattress maintained. The top is soft and comfy and you do not feel any coils nor do you feel them as you sit on the edge.

Rated 5 out of 5 by from Great mattress! [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!

Rated 5 out of 5 by from Sleeping like a princess [This review was collected as part of a promotion.] This mattress has been a wonderful addition to my sleep. It provides support and tremendous relief on my back. I have always preferred a firm mattress for the benefits to my posture and joints and this one is the ticket. It is solid with just enough give in it to provide that overall sense of comfort. Best of all I have finally found a mattress that doesn't cause me to overheat at night! All of my sheets have fit this perfectly and though I imagine this mattress will last a very long time- I will be loyal to the Serta brand from now on!

Rated 5 out of 5 by from So happy! [This review was collected as part of a promotion.] I love this mattress! I’m so happy that we got it! We switched from a 9 year old memory foam mattress and the difference is incredible. Our old mattress was very hot and developed a hump in the middle, with two valleys on the sides, where we sleep. This mattress is not hot at all! It is also pretty firm compared to our old one. The pillow top is really nice and firm too. It is a deep mattress, but I haven’t had any issues with sheets popping off the corners. My husband and I are side and back sleepers and it seems to be perfect for us!

Rated 5 out of 5 by from Amazing Sleep! [This review was collected as part of a promotion.] WOW! After sleeping on this Serta Perfect Sleeper is amazing!! I have lower back problems with constant dull aches to shooting pain. After sleeping on the Cobalt Calm, I can happily say that it has helped reduce my lower back pain! The firmness of the mattress and continued support has helped minimize the amount of stress on my L5 disc. It is such a peaceful sleep, that I'd rather nap on my bed than the couch in the middle of the day! We are now looking to swap out the mattress in our guest room for a Serta Perfect Sleeper so that our family and friends can get the same type of sleep that we do when they spend the night! Definitely Serta for life!!

Rated 5 out of 5 by from Comfortable mattress [This review was collected as part of a promotion.] The Blue Lagoon Nights mattress features Serta's patented CoolTwist Gel Memory Foam technology, which helps regulate temperature and provides targeted support where you need it most. The foam also helps to reduce motion transfer, ensuring that you and your partner can sleep soundly without disturbing each other. One of the best things about this mattress is its versatility. Whether you sleep on your back, stomach, or side, the Blue Lagoon Nights Plush mattress provides the perfect level of comfort and support to help you wake up feeling refreshed and rejuvenated. I have this mattress in my guest bedroom and my guests always comment how comfortable it is.

Rated 5 out of 5 by from Best sleep [This review was collected as part of a promotion.] I got this a few days ago, woooow, I had the best couple of nights sleep that I have gotten in so long. As soon as I laid on it, I sunk in like a cloud was hugging me and oh my, just amazing. Comfortable and so plush! If you love soft conforming beds then look no further because . Just wow. No words on how amazing this mattress is. I’m not for the memory foam technology no matter how much they claim it’s soft so this being a traditional mattress, it doesn’t get any better than this! I 100% absolutely recommend this mattress.

I absolutely love it and so does my husband my back literally doesn't hurt anymore!!!! I used to wake up every morning with back pain , I didn't realize that all I needed was a better mattress!! If you're looking for a mattress and waking up with unexplained back pain then you NEED this mattress!! Highly recommended.

Rated 5 out of 5 by from very pleased [This review was collected as part of a promotion.] I am very pleased with my New Matters that arrived today. I took a nap I was very impressed and pleased with the comfort the Matters provided. I sleeped more peacefully and felt very well rested than my old matters I had. I loved the fact I didn't wake up not feeling hot or cold while I was napping. My dog loved napping on the new matters as well. She slept peacefully as well. We didn't want to get up from our nap at all. This is the best Matters I have ever had in my life. Thinking of getting one for my daughters room.

Rated 5 out of 5 by from A Perfect Night’s Sleep! [This review was collected as part of a promotion.] I am incredibly impressed with the Serta Perfect Sleeper Blue Lagoon Nights mattress. It is the best mattress I have ever owned. It is very supportive and gives a cuddle feel when sleeping. I am a notorious side sleeper, and this mattress perfectly contours to my shoulders and hips. Also, the daily aches and pains I get when I wake up first thing in the morning are gone. I had no idea that my old mattress caused me so much discomfort. I just thought I was getting old. My only regret is not getting this mattress sooner.

Rated 5 out of 5 by from Love it! [This review was collected as part of a promotion.] I love this Serta mattress! I have been telling my husband that the mattress we have was hurting my back more since my car accident so I was very excited to get a new one. The first night we had this mattress I slept through the night for the first time in a long time and didn’t wake up with any aches and pain as I normally do. I love how this mattress has a cushion and is so soft! I highly recommend this to anyone who likes a softer, very comfortable bed! It is also lightweight so it was very easy to set this bed up.

Rated 5 out of 5 by from Truly a perfect sleeper [This review was collected as part of a promotion.] When I had my old mattress although I thought it was ok I was considering purchasing a foot pillow because I could not sleep throughout the night without hanging my feet off the bed. This mattress was a game changer. I sleep so good and comfortable with this. No need for a foot pillow. I love this mattress and it fits perfectly on my bed frame. Great quality. Although it's a pillowtop it has great support.
