  "answer": "Oeuf Dual Firm Crib Mattress: A 2-inch firm edge guard runs around the whole perimeter to support children who are learning to stand. One side is extra firm for infants and the other side is plush for toddlers, so the mattress flips as the child grows.\nBundle of Dreams Flagship Organic Crib Mattress 6\" Dual Stage: It has a 2-inch full perimeter edge guard to support children as they stand. It has a dual-stage design: extra firm for infants and plush for toddlers.\nLullaby Earth Breathe Safe 2-Stage Crib Mattress: The mattress has two-stage dual firmness plus edge support for infants and toddlers. It is a two-stage mattress with a firm infant side and a cushion-firm toddler side.\nLullaby Earth Healthy Support Crib Mattress: Yahoo Shopping describes a firm, durable woven-plastic interior with extra edge support for a standing toddler; sources disagree on construction, with SleePare listing two foam layers.\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. This is a two-stage crib mattress with a firmer infant side and a cushion-firm toddler side.",
