My son loves it

[This review was collected as part of a promotion.] We put this serta mattress in my son's room and he loves sleeping in it. It's really comfortable for us as well for those nights he wants us sleeping with him. My husband and I don't wake with any back pain like we did with his old mattress. 10/10 would recommend

Good Mattress

[This review was collected as part of a promotion.] This bed is comfortable and not too big or small. It's not lumpy or flat. I get really good sleep with this mattress. It holds its shape, even when it's adjusting to my body. It's has a nice pattern on it and it doesn't leave me feeling too hot or cold.

Perfect

[This review was collected as part of a promotion.] The most comfortable bed I have ever slept on in my life. It’s cooling too so it’s perfect for the summer when it’s too hot to sleep. Breathes easy and supports my body weight and heavy dogs with me.

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.

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!

Great support and breathability

[This review was collected as part of a promotion.] This is an absolutely comfortable bed. Didn't know how our old bed was wore out until we felt the support this bed provides. We seem to sleep cool and it breathes well. Great packaging and should last a long time.

Great mattress with wonderful support!

[This review was collected as part of a promotion.] This Serta Perfect Sleeper Quilted Hybrid 24 Knox FM TT Queen mattress is wonderful! It’s comfortable and has improved my sleep quality immensely! I no longer wake up with back pain and it keeps me cool and I do not wake up in the middle of the night sweaty anymore either! This mattress has been a godsend and I love the fact that it’s dark and not the typical white like other mattresses I’ve owned. I really love this mattress and have been recommending it to everyone I know! It’s honestly the best mattress I’ve ever had!

Fantastic support!

This mattress is so comfortable! Perfect amount of softness on the top to support my curves with great firm support beneath. I am just giddy to climb into bed each night. I don't know why I didn't buy a new mattress sooner. I had no idea what I was missing!

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

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
