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.

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.

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.

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

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.
