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 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.

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.

Best Night’s Sleep

[This review was collected as part of a promotion.] I was so excited to receive this mattress! This is the most comfortable bed that I have slept on. Everything from the cooling technology to the perfect balance of firmness to plush. I’ve never had any discomfort from sleeping and I am a side sleeper. I would recommend this mattress to anyone in the market for something new that has great cooling technology and molds perfectly to make a great nights sleep!

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!

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.

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

Such a comfy mattress

[This review was collected as part of a promotion.] So excited to have a Serta mattress! This mattress is beyond beautiful and so stinking comfy. The quality of this mattress is unbeatable and you can tell it’s a quality mattress just by looking at it. I love that this has a plush top but has enough firmness to keep you sleeping comfortably all night. I also love that it is a cooling mattress and doesn’t make you to hot threw out the night. Super impressed with this mattress and can’t wait to continue an amazing night sleep with this beautiful mattress.

Perfect Hybrid Mattress

[This review was collected as part of a promotion.] This Serta mattress has a beautiful design pattern. It provides proper support no matter if I sleep on my back or on sides. The mattress actually has firmness that I was expecting, other mattresses I’ve used in the past deforms memory foam overtime with weight. Hybrid technology indeed brings best of spring and memory foam mattress together.

Sleep Cool and Comfortable

[This review was collected as part of a promotion.] I have spent a full month sleeping on this mattress. I love it! I am a bit of a princess and a pea when it comes to mattresses. Most importantly for me, I am a woman who wakes up hot in the middle of the night. Not sweaty but just hot, not in a snuggly way but an uncomfortable way. I have not had that issue at all with this mattress. It conforms and cradles your curves if you are a side sleeper and it is a very tall mattress which I like. For reference, my previous mattress was a tempurpedic so I was worried about it being too soft but while the top is thick and plus, it has plenty of support. Very pleased with this mattress!
