      We're new grandparent and know more grandchildren will be on the way. We wanted a durable yet inexpensive crib and mattress. This mattress is exactly as described. It is sturdy but not stiff. Our grandbaby seemed very comfortable and we know this mattress will last through many more overnights. Very glad we bought it!

    • A Winner!

      I purchased this as a gift. It arrived very quickly and in great condition. It was exactly what was wanted and the price was considerably less than the one on the baby gift registry elsewhere.

    • Not firm enough for a baby mattress

      NO baby mattress should be this soft - you need a hard mattress to prevent SIDS. Not acceptable. It's also plastic and smells like chemicals when you take it out of the box...

    • Nothing but the best for my baby!

      We shopped thoroughly for a crib mattress. This is a truly great value -- excellent quality and excellent price. Shipping right to the door was quick and much appreciated. Highly recommend.

    • Great mattress for a great price!

      This is a great mattress for a great price. It arrived extremely well wrapped in heavy plastic, so it was well protected from damage or moisture. It arrived only a few days after the order was placed & just in time for the EARLY arrival of our first granddaughter!

    • 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.

    • great crib mattress

      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!
