Start here

Begin with the specific product you need.

Compare products one decision at a time. First identify the household task and product type. Then check important claims against a source that specifically identifies the product, and confirm current purchase details on the retailer's listing.

  • Exact crib and mattress dimensions
  • Which product or component a certification covers
  • Materials used in waterproof layers
What to check

Four things to verify before you buy.

  1. 1

    Put safety and fit first

    Follow current safe-sleep guidance and confirm exact dimensions, firmness, condition, and use instructions before comparing materials or appearance.

  2. 2

    Review each layer separately

    The mattress core, cover, protector, sheet, adhesives, and waterproof membrane may use different materials and carry different claims.

  3. 3

    Confirm the scope of each certification

    Use the certifier's directory to determine whether the standard applies to the complete product or only one material or component.

  4. 4

    Check cleaning and care instructions

    Make sure the protector or cover can be washed and dried in a way that works for your household without affecting its fit or performance.

Frequently asked questions

Common questions about this guide.

Is an organic claim the same as an emissions certification?

No. Organic, textile, material, and emissions standards address different parts of a product and should not be treated as interchangeable.

Where should I go for safe-sleep guidance?

Consult current pediatric and public-health guidance and discuss individual concerns with a qualified clinician. This guide is intended only to help organize your shopping research.
