Firm support, yet comfortable

[This review was collected as part of a promotion.] This mattress is firm and provides strong support. We lay it on the ground to sleep to nurse our newborn. You can lie down or getup without rocking it or disturbing each other. High quality mattress and well constructed.

Great for the price

[This review was collected as part of a promotion.] I recently got the Perfect Sleeper Quilted Hybrid 24 Knox FM TT Queen size mattress, and it's been a game changer for my sleep. The hybrid design offers the perfect balance of support and comfort. The firm feel is ideal for my back, yet the quilted top adds a layer of softness that makes it very cozy. I wake up without any aches, and I notice an improvement in my overall sleep quality. It’s also well-made and feels durable. Overall, a fantastic mattress that delivers both comfort and support for a restful night's sleep!

Cooling technology

[This review was collected as part of a promotion.] After a month of sleeping on the **Serta Perfect Sleeper Quilted Hybrid 24 Knox Plush Tight Top (Queen)**, here are some impressions I have: ### Comfort and Support: - **Plush Feel with Firm Support**: The plush top provides a soft, welcoming surface, while the underlying firm support ensures proper spinal alignment. This combination is ideal for back and stomach sleepers who need solid support but still enjoy a softer surface for comfort - **Pressure Relief**: The memory foam and gel layers do a good job of relieving pressure from key areas such as the shoulders, hips, and lower back, which is particularly helpful if you're prone to waking up with aches ### Cooling Features: - **Cooling Tech**: One of the standout features is the **Cool Twist Gel Foam** and **graphite-infused memory foam**. These layers work well to dissipate body heat, keeping the mattress relatively cool even on warm nights. If you're a hot sleeper, you may notice an improvement in temperature regulation ### Motion Isolation: - **Minimized Partner Disturbance**: The mattress's coil and foam construction does a great job of isolating motion, so if you share your bed with someone, you’re less likely to be disturbed by their movements during the night ### Adjustability and Durability: - **Early Durability Observations**: After a month, the mattress should still feel as firm and supportive as when it was first purchased. The **edge support** is strong, preventing sagging when sitting or lying near the edges. Additionally, it’s compatible with adjustable bases, which adds flexibility for various sleeping positions ### Potential Downsides: - **Plush Might Be Too Soft for Some**: Although the plush top feels luxurious, some users might find it a bit too soft, especially if they prefer firmer surfaces or are heavier individuals, as they might experience more sinkage than they prefer Overall, after a month, this mattress should still feel new, with excellent support and comfort, making it a solid choice for those who value pressure relief, motion isolation, and cooling technology.

Supportive and so comfortable

[This review was collected as part of a promotion.] This is the most comfortable mattress that I've ever owned! I've bought all sorts of toppers in the past to try to make our old mattresses more comfortable but this one has been amazing straight from the box! It didn't need to air out and had zero off gassing smells. I usually feel unsupported on my lower back but this pillow top really fills out your curves and supports everywhere. The floral design is very cute, I do worry that it might pill but haven't had any issues yet.

Best Sleep Ever

We got a new mattress and after much deliberation, went with a Serta. We have no more back or hip pain when we wake up in the morning, it has great support, and I haven’t slept this great in years. Another thing that impressed me was the attention to aesthetics; the embroidered flowers on the mattress top are lovely. Thank you Serta!

The best sleep in years

I had my other mattress for 15 years, and it was great until the last week. I knew I had to replace it. I went to Mattress Peddler as I had been there when friends mattress shopping and was impressed with the professionalism and kindness of the owner. I love the mattress I purchased. Just the right firmness. I am so happy

Great night sleep on this firm, pleasant cooling effect, high quality material and beautiful design pattern

[This review was collected as part of a promotion.] Great mattress! I was very excited to finally get a new mattress and I had such a great night of sleep after sleeping on this Serta one. My previous mattress was softer, and I had been waking up with some back pain, but this mattress is firm and helps a lot with my back and hips not sinking in as I sleep. It has a pleasant cooling effect so I didn’t feel overheated at night, and I love that it’s thicker as I like to sleep higher up off the ground since I am tall. It was such a shame to have to cover up the mattress with my bedding as I loved the design and dark blue and white color patterns. It also has helpful handles on the side so you can adjust it as needed on your bedframe. It’s on the heavier side, but most of my mattresses in the past have been heavy as well so I didn’t mind that. I prefer a heavier mattress, so it feels more sturdy when I am on the bed. I would definitely recommend this to anyone looking for a firmer high quality mattress!

It offers everything I need

[This review was collected as part of a promotion.] This mattress strikes the perfect balance between firmness and softness. The hybrid design combines the support of coils with the plush comfort of memory foam. It’s firm enough to provide excellent support for my back, which is crucial after long days of household chores, yet soft enough to feel like I’m sinking into a cloud every night. One of my biggest concerns with mattresses has always been overheating during the night, but the Perfect Sleeper has really impressed me. The quilted top layer seems to do a great job of regulating temperature, keeping me cool. The build quality of this mattress is outstanding. It feels sturdy and well-made, and after several weeks of use, there’s no sign of sagging or wear. I believe this mattress will last for many years, which is a relief because I definitely don’t want to go through the hassle of mattress shopping again anytime soon! One unexpected bonus is the excellent edge support. I can sit on the edge of the bed without feeling like I’m going to slide off, which is great for those moments when I need to slip out of bed quietly without waking anyone else. Overall, it has been a wonderful addition to our home. It offers everything I need in a mattress: comfort, support, durability, and a cool sleeping experience

Have you ever wanted your bed to give you a hug?

[This review was collected as part of a promotion.] This bed was put into our guest room and it might be more comfortable than my bed. With the right mattress protector, the mattress is surprisingly cooling and cozy in both hot and cold weather! The mattress has the perfect balance of plushness and support for your body. I would recommend to anyone looking for a new mattress.
