Mattress Suggestions

[katharsis]

I know this might not be the right forum, but hey we all need to sleep!

I'm way overdue to get a new mattress.
Currently we have a coil mattress and start to feel the springs popping out.
It's a few years old and becomes really bothersome (keep tossing and turning and wake up a few times during the night).

I'm a side sleeper as where my g/f mostly sleeps on her back.
We have tried a few but are really unsure of what to get and each store you check at the sales associates tell you something different.... it's almost like going to car dealership!

The only things we do know - it needs to be queen size to fit the current frame and be somewhat firm.

Any suggestions? What do you use?

I was mostly checking out latex mattresses but heard that you need to make sure that they are all organic as some people actually developed allergies towards "processed" latex.
