memory foam mattress owners- did yours get harder or softer over time?

i bought a queen memory foam mattress (not a topper, a full mattress), either posted here on HD or on FW, from Amazon about a year and a half ago.
it was a good deal, around $500 iirc. obviously not a $1.5k temperpedic or anything.

reason i got it was because i sleep on my side and used to wake up in the morning or even middle of the night with severe shoulder pain.
i tried a 2" foam topper and it instantly went away, so i thought a full mattress must be even better and it did not disappoint.

1.5 years later, i'm having shoulder pain again and was wondering if the mattress is no longer contouring to my body.

so for you guys out there that have one, have you noticed whether this was the case or not?

hmm... i thought it was perhaps just mine.
or because it's colder so it's not as reactive. but i didn't notice it last winter.

It's Vehemence. Take nothing seriously that he says.

Mine became less squishy. As in, it got squished down and stayed there.

i knew there was going to be innuendo with that thread title but i decided to go with it anyway.

ok, so basically the opposite of mine. mine feels pretty firm, much like a regular mattress.

I recently purchased a simmons beauty rest and after a year it has completely sunk. I was looking at buying one of the memory foam mattresses or the sleep number bed, so it would be good to know if this they change density.

Mine was hard for over 4 hours one day so I didnt call a doctor, I called every chick I know and even some I didnt. Then all of a sudden it was soft again.

Ours has stayed the same. It'll be firmer in a cooler room and slightly softer when you lay in one position for a few hours or keep your room/house warmer.

I have a temperpedic and it's pretty much the same as the day I got it 2 years ago.

I've noticed that with my memory foam pillow. In the winter if the bedroom gets really cool that thing can turn into a brick. Not something you just want to drop your head onto. But it gets a little more comfortable once it warms up a bit.

Same here. One of the best purchases I have ever made. :)

i have a 4" topper. it worked beautifully for a year or two. then i started having some of the backaches i had prior to getting it.

the foam is still as soft as before, but it lost a lot of its supportive ability over time. what happens is the outer surface develops fissures/tears/rips in the foam from your body rolling around and other motions. the effect is like scoring the surface with a knife. instead of being supported by one large surface of foam, you are on top of a bunch of small cubes of foam. since each section is no longer connected to each other, an individual cube/section is able to compress more than it would if the surface was intact and surface tension was keeping any point from being compressed too much.

full foam mattresses with inner cores may do better, but nothing will prevent the foam from tearing and losing supportiveness.

I've had mine for two or three years. I think the memory foam top of the mattress has gotten a little softer (less resistance) where I normally sleep, but the result is that I sink down to the normal foam bottom more easily, which is harder. So I can feel my hip against the harder foam now whereas before, I couldn't.

That said, it is still so comfortable that I hate sleeping on normal beds. Whenever I get home from a trip and lay down for the night, it's like "yeeeeeah..."

Your memory foam has developed Alzheimer?s.

Interesting about the shoulder pain. Mine's been killing me lately too, might have to go full foam matress if that works!
