cot mattress?

hi all, was just wondering if anyone had any recomendations or suggestions on what to look for in a good cot mattress?

When we were looking for a cot & cot mattress ... every shop we went into the staff said " You MUST GET a SPRING cot mattress not foam" ;)

Yet i have been told by a midwife who works for SIDS that a firm foam matress is ok.

i have an innerspring 100% australian mattress for the cot. I think its worth hunting around for a good one... HTH

With my DS. I brough an ezibreathe mattress from Babies galore ( about $140)... it had special vents so if bubs did end up on his tummy air still was able to come through the mattress... Also i have noticed although the mattress is important also the mattress protector is too... I had one that had a plastic backing and was informed that if bubs did as mentioned end up on the tummy this would indead suffocate the little one...

Also i read that a new mattress should be brough every 2-3 yrs for cots. which is why we purchased a new one (same ezibreathe)
