I've only had my mattress for a little over 2 months, and it's already sagging in the spot where I usually sleep, in the butt area. I only weigh about 135 lb, and this shouldn't be happening yet. I'm I'm scared, if it's sagging now it's such a early point, what's going to happen six months from now.

It's been a week since I got my mattress. It's fantastic; I no longer wake up sweating in the middle of the night. However, the only downside is that I've noticed the area where I sleep feels a bit more sunken than usual. Even after spending hours out of bed, it doesn't return to its original state.

It's so thick and it's not to soft. It's big enough for me and my special needs daughter to have room to sleep. I absolutely love it!!

[This review was collected as part of a promotion.] This Serta Perfect Sleeper mattress is finally THE mattress I've been looking for. The mattress is so soft and plush. It forms to my body but does not lose its shape. The mattress is so comfortable and I fall asleep easily on it. There is a reason this mattress is called a perfect sleeper, This mattress is extremely soft to the touch but when you lay on it you can feel it firm up and you don't sink. The sides tend to be softer than I would love but not enough to be a problem. Each night that I have slept on it has been great to which it has been very comfortable. I would definitely recommend the mattress to anyone since it has improved my sleep and back pain.
