Comfortable

[This review was collected as part of a promotion.] ABSOLUTELY AMAZING! I can't believe I received a mattress, an extremely comfortable one at that! It adds so much to the room. The height is great & completes the room. The design on the mattress is very intricate. Good support, durability, and comfort. It's soft yet firm. Love this mattress!

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!

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.

Firm and hefty!

[This review was collected as part of a promotion.] The Perfect SIeeper Quilted Hybrid was aesthetically, a very clean beautiful mattress with quite a bit of thickness and heft, which made setting it up a bit challenging without assistance. The weight does add to the sense of durability and sturdiness. I was pleasantly surprised to find no odor, which is often an issue with newer mattresses. Most notably though, the mattress is quite firm, which is the style I selected. It's exactly as advertised, very firm. There is little cushion or give but provides great support. I would not recommend this mattress if someone wants to "sleep on a cloud" but rather, would be ideal for those needing extra back support. For anyone looking for a firm mattress that feels built to last, this one would be a great choice.

Better sleep and comforting! Great for my back.

[This review was collected as part of a promotion.] This mattress has been a huge help to the quality of sleep that my wife & I get. Before we had a firm memory foam mattress & it was causing some morning discomfort for both of us. After receiving this mattress it took a week or so to break it in but we have both been sleeping so much better & having little to no discomfort in the mornings. I will say it’s a bit too stiff to sleep on your side with but other than that it’s a great mattress overall. Great material & quality which makes me hopeful it’ll last many years.

Bad quality

I just started sleeping on this mattress and it has a horrible bubble in the middle. This is the cool calming queen mattress. It's a replacement for a different mattress from serta and it only lasted 6 months before the sides started caving in. I will never buy a serta mattress again.

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.

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 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!

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.
