Used this mattress for my son for a couple years until he outgrew it over a year ago. Was hanging onto it in case the family grew but plans have changed. Organic two sided crib mattress with infant and toddler sides of different firmnesses for infant safety. We didn’t use the infant side because my son was 18months old when I bought the mattress. Mattress is clean and seems comfortable and durable. Always used it with mattress cover. Waterproof mattress covers are machine washable in cold water, hang dry only, do not put in dryer. Please take mattress and covers as a set. Having two covers means you can use one while the other is being washed/hanging to dry (which takes about a day or two depending on the room temperature). I liked to hang them inside out to assist with drying. Mattress and covers are from TJ Kiddies Victoria. You pick them up please.
