I am very pleased with this mattress. My son was sleeping on it as king! All swedes, I guess, have this one for their kids and they can't have wrong! This mattress is soft but not too soft so it comfortable for baby. It is eazy to wash! Removable, machine washable cover.I did it many times and nothing happened with form or how it looks. I recommend that the mattress should be at least 3,9 inch, for you as a parent should be easier to lift up or put down your baby in the crib, then it is the right depth on this IKEA mattress. We used the mattress rather just a year, but with the quality they had children safely sleep on it for several more years.
