Bests & Worsts Reviews from Amazon

***Is NOT waterproof*** OR urine proof for that matter. I bought this since it was Amazon Choice and lots of good reviews. Well, that was a mistake. My son has accidents maybe once every few months and had one last night. I removed the soiled linens and "waterproof" liner and found that mattress already soaked! Unless you enjoy extra work cleaning a mattress and smelly urine residue then DO NOT BUY!!!
