Crib Mattress Buying Guide



Information Important things to know about crib mattresses safety:

  • ALL crib mattresses sold in the USA must meet state and federal flammability standards in order to be sold in the USA. As of this writing include both 16 CFR 1632 Cigarette Burn Testing plus the more stringent 16 CFR 1633 Open Flame Test which includes 2 torch tests that examine heat and burn time. If the materials don’t pass these tests, they are not on the market today.

  • ALL crib mattresses sold in the USA pass the Consumer Product Safety Improvement Act of 2008 (CPSIA) which tests for 6 types of phthalates, lead, and other potentially harmful substances. If the mattress components don’t pass these tests, they are not on the market today.
  • CRIB FIT: Crib mattresses are designed to fit inside USA-standard full size cribs and toddler beds. The dimensions will soon be mandated by ASTM and eventually the ASTM standard will become federal law in order for mattress sizes to be consistent.

  • How to take Crib Measurements: When possible it is a good idea to measure the inside dimensions of your crib to ensure they comply with the standard.

  • Measure the INTERIOR of your crib to the below specifications. The inside of your crib should measure somewhere between 27 3/8 to 28 5/8 inches wide and between 51 ¾ and 53 inches long. Mattresses are designed to be slightly smaller to allow them to fit within these tolerances.

  • Make sure there is no more than an 1 ¼” gap between the mattress and crib

  • All crib mattresses must not exceed 6 inches in height (when lying down in a crib) when measuring seam to seam. Sometimes shipping dimensions of a crib mattress are shown thicker if they are bagged or boxed but they should not exceed 6 inches seam to seam.
