New Serta Mattress

Comfy and supportive, everything my back needs! Worth every penny!

Amazing mattress!

2 1/2 months in and my husband and I still haven't adjusted to this mattress. It does not have a cooling effect whatsoever, in fact it holds heat. We both wake up with back pain. Now we're stuck with it and stuck with poor quality sleep. If you're looking for a new mattress, don't buy this one.

Horrible

We absolutely love our Serta mattress! At first, it felt a bit stiff, but after a few days of breaking it in, it became incredibly comfortable. We made the switch from our previous pillow top options because they kept breaking down too quickly, and we're so pleased with our decision. This mattress provides great support and feels much more durable. Overall, we couldn’t be happier with our purchase!
