  "title": "Kids' mattresses with a firmer infant side and softer toddler side that flip",
  "question": "Which kids' mattresses have a firmer side for infants and a softer side for toddlers, and can be flipped between them?",
  "answer": "Moonlight Slumber Little Dreamer Mini Crib Mattress: The dual-sided design is presented as a way to flip from a firmer infant side to a plusher toddler side instead of buying a second mattress. Flipping: To change stages, flip the mattress following the arrows on the mattress tag.\n\nBabyletto M53102A / BYL-M53102A: The infant side is firmer and the toddler side is softer. The mattress is dual-sided, with different firmness levels intended to grow with the child.\n\nOeuf Dual Firm Crib Mattress: One side is extra firm for infants and the other side is plush for toddlers, so the mattress flips as the child grows. A 2-inch firm edge guard runs around the whole perimeter to support children who are learning to stand.\n\nModera Baby MOD-CBN1222: The 5.5-inch build is described as firm and flat for infants, then softer gel foam for toddlers. Some customers report zipper issues, and some parents find the memory foam too soft for newborn safety comfort.\n\nMoonlight Slumber Little Dreamer Crib Mattress: The review named it an upgrade pick for foam, praising true dual firmness, clear side labels, a seamless wipe-clean cover, and light weight.\n\nKalon Dream No.1: It is flippable with dual firmness for infants and toddlers. The mattress is not waterproof and does not come with a washable cover; the blog recommends pairing it with a wool puddle pad for moisture.",
