[This review was collected as part of a promotion.] This is a super thick and ultra firm mattress that took my back pain straight away. Aside from being extremely comfortable this is super cooling and breathable, I live in Arizona and this made night time so much better. I would definitely recommend this mattress to a friend!

[This review was collected as part of a promotion.] I was beyond excited to receive and review this mattress for Influenster. I was struggling to get good sleep and my mattress was causing me a lot of joint pain. I have never liked firm mattresses before, so I thought I had chosen a medium firmness. When I received the mattress it was very firm. I decided to give it some time. Quickly I noticed I was falling asleep faster and staying asleep. I felt more rested, even as a new mom. Over time the mattress began to soften a little, but still provided a lot of good support. My body and joints don’t hurt as much, and I find the cooling technology seems to be working. I am really impressed with this mattress.

[This review was collected as part of a promotion.] The comfort of these mattress are unbelievable. I am a mom of two my back was hurting so bad until I got this . There so much deport. I feel awake it breathable. All my kids and adults can jump on this mattress super durability.

[This review was collected as part of a promotion.] The flat and stable mattress surface, high hardness, can support the entire body of the person lying on it, the mattress is very effective for people with spinal pain. Convenient for moving and cleaning. Both mattress surfaces are flat, have even thickness, and are not concave or convex, so they effectively protect the back area. The mattress is suitable for all customers, especially children in the development process, the elderly with bone and joint deterioration, people with back pain, office workers with neck and shoulder pain... The completely flat mattress surface with a cool, smooth feeling is very beneficial for shaping a straight skeleton, good blood circulation during sleep. It is a perfect choice for a good night's sleep.

[This review was collected as part of a promotion.] My Mattress: Serta Perfect Sleeper X Quilted Hybrid - Queen, Level 2, Plush Pillow Top Upon delivery, it was immediately apparent that this is a quality mattress. From materials, to design, to craftsmanship, it embodies luxury. It's plush, stable, and supportive. It also comes with conveniently placed handles on the sides that make it extremely easy to move. I also really love the fact it's not white, which can quickly show signs of wear even with a mattress protector. The first time I laid my weary bones upon my newly bequeathed mattress, it felt like my body left the mortal plane and ascended to the stars. It was like sinking into a cloud of hugs and marshmallows. I'm not ashamed to admit that it brought a tear to my eye. (Ok, several tears). Long story short, sleep is my frenemy. I have a connective tissue disorder that causes weak joint connections and severe chronic pain. My joints shift and dislocate easily, especially if I sleep "wrong". In the past, I've woken up more injured than I was before I want to sleep. I love sleep, but it doesn't love me back. In a month of sleeping on this mattress, I have experienced such pain relief that I am not the same person I was prior. My joints feel more stable, my back muscles stopped constantly spasming, and my hips and shoulders no longer feel like they’re collapsing in on themselves. I wake up feeling genuinely rested, which has been nearly impossible for me in the last few years. The pillow-top layer is perfect for side sleeping. It has a memory foam quality that conforms to my body, leaving my shoulders and hips supported without feeling crushed. The layer beneath the pillow top is supportive with great bounce and weight distribution. I never wake when my husband gets up for work, which attests to the quality design. I also love that I never feel too warm, which has been incredible as a very hot sleeper. My only complaint is that I never want to get out of bed!! Serta, you have ruined me for all other beds. This mattress has given me more than a good night of sleep, it has completely changed my life. If you're shopping for a new mattress, look no further than the Serta Perfect Sleeper X. It's worth every penny and then some!! TLDR// Pros: Perfect for side sleeping, luxuriously plush and supportive, significantly reduced chronic pain and joint stiffness, distributes body weight evenly, very cooling, quality craftsmanship Cons: You will never want to get out of bed ever again I received this product in exchange for my honest review.

[This review was collected as part of a promotion.] I’m coming from a purple mattress. I wanted something g a little bit more firm. This did the trick for my lower back. I think the combination of the hybrid of foam pan springs that gives optimal support. I live in Phoenix, the cooling this mattress has beat my purple hands down.

[This review was collected as part of a promotion.] This mattress changed my life. I previously had a complete memory foam mattress, and didn’t realize over time how they wear down. When I got this mattress I was surprised to see how well built and sturdy it was, and immediately noticed when I laid down on it how plush it felt. I’ve had this mattress for about a month now, and I can say with certainty I sleep better now than I have the last 10 years. I no longer wake up with aches and pains, I feel well rested, and actually look forward to laying down for bed at night. One thing that also really stuck out to me, was that it actually has a cooling sensation to it as well. As someone that likes to sleep cold, I had doubts about this feature. Tested and true though, I am OBSESSED with my bed!
