  "question": "Which crib mattresses have a waterproof surface?",
  "answer": "Naturepedic Breathable Organic 2-Stage Baby Crib Mattress: The removable washable cover over a wipable waterproof surface is described as solving a real overnight-leak and spit-up problem. The removable machine-washable breathable layer doubles as a built-in mattress protector.\nBabyletto M5321C: The cover is removable and waterproof, with a soft quilted cotton face and a PVC-free waterproof backing made of food-grade polyethylene. The cover has a zipper closure and square corners designed so a crib sheet fits seamlessly.\nNaturepedic Breathable Organic Oval Crib Mattress (SKUs MK46V2 and MK46V3): Breathable crib models have removable machine-washable covers and the waterproof surface underneath is wiped clean. The maker's own store sells the V2 mattress with cover as SKU MK46V2 and the V3 with cover as SKU MK46V3, and a cover-only option for each size.\nLullaby Earth Healthy Support Crib Mattress 2 Stage: Review calls it an affordable non-toxic crib mattress with MadeSafe and Greenguard Gold certifications, recycled materials, dual firmness, a waterproof wipe-clean surface and decent edge support.\nLullaby Earth Healthy Support Crib Mattress: LeafScore describes recycled polyester and a food-contact-grade polyethylene waterproof surface; sources disagree on construction, with SleePare listing two foam layers.",
