WORST MATTRESS After four days i'm sleeping in a sinkhole

[This review was collected as part of a promotion.] Excellent mattress. It's soft but offers great support. Very comfortable. Prior to this mattress I'd wake up with back pain. I now sleep more comfortably and I get a good night's rest. Very happy with it.

[This review was collected as part of a promotion.] I'll admit our last mattress was beyond its years so anything likely would have been an improvement. This mattress goes above and beyond. It is on the firmer side, but not anywhere near hard. Firmness is perfect for our family. Bed the mattress is on is in our college sons' room so not only is it a sleeping place, but game playing and whatever else goes on in his room. He has stated it is much better than what he had before. Guests also use this room when visiting and college son is away; comments about sleep have always been positive.

[This review was collected as part of a promotion.] This bed was absolutely terrible. It broke apart in less than 3 weeks. I was sleeping on it and woke up in a hole because the inside of the mattress broke apart. And then two days later the other side of the mattress that my other half was sleeping on had the same thing happen to them. I am very unsatisfied with this and will not be getting another mattress like this anytime soon.

[This review was collected as part of a promotion.] The Cobalt Coast PL TT 13” Mattress has exceeded my expectations! It’s definitely the most comfortable mattress that I’ve ever slept on! It has just the right amount of cushion, but it’s still firm and supportive. The quality is superb, it’s stitched beautifully and extremely well constructed. A huge plus is that the mattress doesn’t bounce around, and when my wife or I roll over, the other one doesn’t feel a thing. I feel like a king sleeping on it & haven’t ever gotten such great sleep! This is an awesome, comfortable, supportive yet soft mattress, we absolutely love it!

[This review was collected as part of a promotion.] Serta has made an amazing matress. The Cobalt Coast Plush Pillow Top has improved my sleep exponentially. It is such a soft, comfy feel. I paired it with the Serta Motion Perfect Adjustable Base. The matress is 15" deep and is compatible with any Serta base. The inside of the matress is a coil system encased in a gel foam. The HexCloud gel system is designed to be cool to the touch and stays cool throughout the evening. The matress top is pillow soft and makes me feel relaxed. The matress holds its shape as I don't sink into a spot over the course of the night. It is nice to lay in this bed to watch TV, read a book or converse with my significant other. My quality of sleep has improved so much. Serta hit a home run with this Cobalt Coast matress. Highly recommended.

[This review was collected as part of a promotion.] It is like sleeping on a cloud so comfortable. My husband is able to get a full night sleep which has been impossible for years. I do have to use a stool to get in bed but it is worth it for the comfort. I will be recommending this to family and friends who are looking for a new mattress.
