Buying a new mattress for cosleeping, but which one?!

[ovumahead]

Hi everyone

We currently have a latex mattress (natural but a bit warm and squishy so I don't think any good for cosleeping). Just looking online for new mattresses, and getting confused. Have read up a bit about cosleeping safety, some sites seem to recommend organic mattresses to avoid the chemicals that get released into the air from standard mattresses. When we Co slept with my ds we didn't have a fancy mattress at all,but also didn't research things quite as much! Any tips or advice welcome....

Well we bought a ridiculously expensive organic mattress with a gazillion springs so hopefully that will suffice!
