We got a Colgate one and it is great! It is very lightweight, which you will appreciate very much the first time you have to strip the bed in the middle of the night. Plus- the one we have is very firm on one side and reverses to a softer side for when he is a little older. I have been VERY pleased with this purchase.
We went for the Colgate Classica Foam also. It is sooooo much lighter and there is no way in the world that it will get worn out, even if you want to use it for later babies.
Re: Crib Mattress
Here is what Baby Bargains says:
Best foam mattress (which they prefer over coil): Colgate Classica I ($100, www.colgatekids.com)
Best coil mattress: Sealy Baby Ultra Soft ($85 at BRU) or Simmons Super Maxipedic ($115 at BRU)
HTH!
We got this one from Costco:
