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!

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

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!

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.

Best sleep I’ve had in a long time!

[This review was collected as part of a promotion.] This mattress is amazing! I didn’t know how badly I needed a new mattress until I received this one. I had the best nights sleep ever, I woke up feeling refreshed and ready to go for my day! The mattress itself is so comfortable and has just the right amount of firmness. I also like the quilted material of the mattress and the height of it. It is definitely worth the price and I am so happy to have it.

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.

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.

Super comfy

[This review was collected as part of a promotion.] I couldn’t be happier with it! From the moment I unboxed it, I could tell it was a high-quality mattress. The hybrid design combines the best of both worlds with a comfortable foam layer and supportive innerspring coils, making it incredibly cozy yet supportive. The medium-firm feel is perfect – it strikes just the right balance between softness and support, making it ideal for a restful night’s sleep.
