innersping vs foam cot mattresses

We have innersprung, were told at AN that foam doesn't breathe plus from experience we had a foam mattress for guests and it somehow went mouldy though not sure why exactly!

To me, foam mattresses seem more 'chemically' (I imagine a machine that just pumps them out into moulds.... bleugh!! ) so we bought an innerspring one for our son.

We also have an inner sprung mattress, I was the same as caliandjack - I wouldn't want to sleep on one so I wouldn't expect DS to either!

I found the foam too spongy and just not good for his back - especially for babies who would sleep so often on it!

We also have an innerspring cot mattress.  Foam probably wouldn't last as long either, I'm guessing.

If you go with foam you need to make sure you get a dense foam as they hold their shape better than the cheaper versions. Foam mattresses are less suspectible to allergens as springs can often collect dust particles.
Innersprung are said to provide better support - however, I understood that when they are so little that level of support is redundant as they don't weigh enough to necessitate it IYGWIM. I think if you are looking for a mattress to use with more than one child though, innersprung would be the way to go as they last longer. For us the allergy thing was a big consideration with DD2 as I have terrible allergys as does my oldest child... still haven't decided what we're gonna do this time...

We went with a dense foam. As freckle pointed out, the teeny weight of a baby means the lumbar support of an inner sprung mattress isn't actually necessary. I spent ages trying to find info/studies/anything online about which was "better" and then ended up talking about it with my SIL and a few friends with older kids. A couple of them pointed out the weight thing. Even at >10kg DS didn't "sink into" his cot mattress at all!

He has an inner sprung mattress now that he's in a bed as he will be in that for a good few years to come, I hope!

A got a free mattress when I purchased my cot decision made.

We use foam and it's not a problem I am intending on getting a new one for the next baby. I put it in the sun to air on sunny days and regularly flip it too.

I agree that they don't make a dent in it at all! It is dense foam. When she goes into a proper bed she'll have a inner sprung mattress

The cot we were gifted came with a foam mattress, quite a nice firm dense one. Bubs sleeps well on it and sleeps well when he's with us on our sleepyhead kingsize. We've got no preference at the moment but wouldn't go for the cheapo flimsy foam mattress at all. Might as well sleep on nothing they're such poor quality unless you layer it with a thick blanket before the cover sheet.
