The Kolcraft Crib mattress was the first mattress I purchased for my daughters crib. Initially I thought that it felt firm, would be easy to wipe clean and was at a great price. However, once I got it home and took it out of the bag I decided that this wasn’t going to be the mattress she would be sleeping on. First of all as soon as I took it out it had a lot of off gassing, it needed to be left out to air out for several days and even then the surface still had more odor than I would ever want for my little one to be sleeping on, regardless of the protector and sheets over it. The second thing I noticed was once I put it on the crib it felt like it wasn’t as firm as it should be. Both of these reasons along with the low price tag were enough for me to look at other mattress options.
