    • exactly as advertised

      I read a lot of reviews for various mattresses before settling on this mattress. This mattress fit our crib perfectly (Ava by BabyMod from Overstock). The mattress seems thick and firm enough, and made of high quality material. Very satisfied with this mattress!

    • Poor Quality

      I purchased this crib mattress for our new baby. He was only sleeping in it for about 4 weeks when I noticed it sinking where he slept. It did not bounce back like a normal mattress does, and you would think it would since a newborn is not very heavy. I contacted the manufacturer Kolkraft about this issue, and they asked me to email pictures of this mattress so the quality team could review it. I sent it with the sheet on since it was easier to see the sink hole, because the plain mattress has an all over pattern on it. That wasn't good enough and they wanted to see pictures without the sheet. I re-sent pictures with the sheet removed and that wasn't good enough. Now they want to see another picture taken at a level angle. I'm sorry, but I have a newborn that does sleep a lot and I work. I don't have time to keep going back and forth taking pictures, and not to mention that it is hard for a baby to learn to roll over when he is sleeping in a hole. I am very disappointed with the quality and the customer service concerning this product.

      This is a great crib mattress. There are cheaper mattresses out there, but you get what you pay for. This is a high quality mattress that will not wear out before you are done using it. Thanks Sealy!

    • Great Buy

      I started my mattress search by researching standards and recommendations to look for while shopping. This mattress not only hit each of those categories of safety and quality, but also came with a reasonable price tag. After comparing multiple websites and mattresses, coil counts, reviews, etc. I landed on this mattress as my final decision. I am still very happy with my research/decision!
