Do mattresses have a break in period and become softer after a couple of months?

So in september I got a Sealy Cooper Mountain firm... (I was stupidly assuming I needed a "firm" mattress because of back aches coming from a very worn out mattress that was soft...)... I slept on it for 3 months but it was just so uncomfortable I exchanged it for the Sealy Cooper Mountain plush eurotop; the plushest on us-mattress.com... well I get it.. and it has this huge thick soft pillow top but when I lay on it, it's still rock hard.. what the hell? I think it's because the springs are so firm..

basic foam in a bed (regardless of polyurethane, latex or memory) needs to be broken in. If you walk or crawl on it ( I like an even pattern from head-to-toe and side-to-side) allows you to "crack" any and all foam cells so that it is pliable like a broken in foam layer.
think of it like a new pair of dress shoes that you only wear a short while the first couple of times (or at least do not walk in for 8 hours) so that you "break them in" and you do not kill your feet the first day.
give it a couple of weeks if you only sleep on it to break it in but then do expect to have a dip (both seen and felt) where you sleep and enter the bed vs where you never touch...

I think because the foam layers are weak and have compressed bringing your body directly in contact with the spring architecture. You may experience a "hammock effect" resulting in low back pain, especially if you side sleep.
I'm new here so I would not suggest surgery but the same thing happened to me years ago with a sealy pillowtop. After 9 months I ripped the pillowtops off but I still ended up ditching the set. Plus, I think sealy uses the Bonnell coil. Not good as they lock up after any amount of compression
Good luck. I am so glad I found this room because I have gone thru many ordeals just to get a good sleep

Sealy's coil used to be the bonnel (posture-tech coil) but they went to a pocketed coil in the last 18 months... their introductory Posturepedics still use the wire-laced as well as the "Sealy" line, but the majority of the Posturepedic line is now pocketed, "titanium blend", tempered coils. I will say whenI asked how much titanium, I was informed that it was "enough" to do the job.
Also, since he has not had this bed but a short time, I doubt he has compressed all the way to the coil structure so quickly.
