I've had my mattress for about 9 months now and I'm pretty disappointed. I'd say by month 6 it was already feeling like we were sinking into the middle. The topper was really nice at first but now it's just kind of bunched up in places. Overall it's still an okay mattress, it just didn't live up to my expectations for the cost. I was deciding between this and the Purple mattress and I wish I would've gone with the Purple.
