[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.

Wish This was first choice when I pick out my first mattress sleep much better

[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.] Got this a few weeks ago and happy I did. My back feels great and so of the best night sleep I have had in awhile

[This review was collected as part of a promotion.] After a week of sleeping on it, I have been waking up with no back pain. The mattress really supports my back. I’m sleeping more comfortably and it is great! When I opened the mattress. I recommend this mattress to anyone who needs back support when sleeping!

[This review was collected as part of a promotion.] I've never been able to sleep well, and I usually toss and turn all night. This mattress has made a world of difference! It is so comfortable, and my body doesn't ache in the morning like it used to. It cushions my body to where I don't feel pressure on my back or shoulders, but doesn't feel too firm. I'm usually really hot when I sleep, and I wake up feeling sweaty. This has really changed that, because it's so breathable and keeps me cooler. I love the quality; it's sewn with no loose strings or frayed fabric, and I think it will hold up against wear and tear and last a long time. I think it's a good mix that it has both coils and foam, because it provides great support while still feeling soft and comfy. Serta has always made great products, and this is no exception.
