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!

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.

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

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.

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.

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.

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 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.

Great mattress - beautiful, well designed, and very comfortable

Love this mattress. Beautiful design and very comfortable. It has good support and a lovely cushioned top. Independent coil design with five comfort points is ingenious. We looked at every other brand, and this mattress was by far the best-designed and most competitively priced one we could find. Highly recommended.

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.
