How did you actually know when you found the right mattress?
I've been realizing how hard it is to judge a mattress in a store. You can lie on one for 10 minutes and think it feels great, but that's obviously very different from sleeping on it every night.
For those who recently bought one, what made you feel confident that you'd found the right mattress? Was it firmness, support, the way you slept on it for the first few weeks, or something else?
I'm starting to look around and honestly have no idea where to begin.
