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.

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.

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!

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.

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.

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.

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.

Sturdy, yet soft like a pillow.

[This review was collected as part of a promotion.] The bed is incredibly comfortable. The top is soft like a pillow, but the whole mattress feels firm. The pattern on it is cool but doesn't really add anything to the performance of it. This is a perfect choice for back sleepers or those who sleep on their stomach. Amazing product with an amazing quality feel to it.

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.
