A non-toxic nursery checklist, zone by zone

It is a goal, not a certification. Nothing on a product tag certifies a whole room, and a product described as non-toxic may or may not have been tested by anyone. So this checklist avoids the word where it can and names the specific concern: lead dust, volatile organic compounds (VOCs), or what a fabric was made from.

It also keeps two kinds of risk apart. Material choices are about long-term, low-level exposure, where EPA itself says not much is known about health effects at the levels usually found in homes. Sleep position, loose bedding and unanchored furniture are immediate hazards with clear rules. When the two compete for your attention or budget, the second kind wins.

The American Academy of Pediatrics (AAP) and the Consumer Product Safety Commission (CPSC) agree on the basics, and none of them depend on what the mattress is made of. If you have questions about your own baby's sleep, ask your pediatrician.

Once the safety rules are met, labels can help with materials. For a mattress, GREENGUARD Gold is the one aimed at air: UL Solutions says it sets lower VOC emission limits meant for places such as nurseries and schools, and limits emissions of more than 360 VOCs. It does not tell you what the mattress is made from.

For that, look to GOTS, the organic textile standard. GOTS says a certified product must contain at least 70 percent certified organic fibers, and at least 95 percent to be labeled organic. Check what the certificate covers. A GOTS certified cover is not a GOTS certified mattress.

Our pages on organic crib mattresses and organic crib sheets state which part of each product is certified. An organic mattress still has to be firm and fit the crib.

Start with the age of the house. EPA says a home built before 1978 is more likely to have lead-based paint, and that dust and chips from that paint are among the most common sources of lead exposure at home. Paint in good shape is usually not a problem. Peeling paint and renovation dust are.

That makes sanding or scraping old paint in a future nursery the wrong do-it-yourself job. EPA's Renovation, Repair and Painting rule requires anyone paid to disturb painted surfaces in pre-1978 homes to be certified and trained in lead-safe work practices. Ask for that certification.

New furniture is another source. EPA lists building materials and furnishings among the things that emit VOCs, and names formaldehyde as one of the few indoor air pollutants that can be readily measured. Its advice is to identify and, if possible, remove the source, and otherwise to ventilate. Unboxing and assembling furniture early, in a room with open windows, follows the same logic as painting early.

For labels, GREENGUARD Gold applies to furniture as well as mattresses. See non-toxic cribs and nursery furniture for which pieces carry it. Solid wood, FSC certified wood and water-based finishes are material claims, not emissions tests, so treat them as separate facts.

Then anchor it. CPSC's Anchor It campaign says anchoring all furniture with drawers, doors and shelves to the wall prevents tip-over injuries and deaths. CPSC notes that a federal rule to prevent furniture tip-overs took effect on September 1, 2023. Older and secondhand pieces predate it.

At the changing station, the AAP recommends a sturdy table with a 2-inch guardrail on all four sides and a pad with a concave top, and says never to leave a baby unattended on it, strap or not. It also says not to use baby or talcum powders. Our page on organic changing pads covers pad materials.

EPA reports that levels of several organic compounds average 2 to 5 times higher indoors than outdoors. The reliable fixes are plain ones: fewer sources, and more fresh air. Our guide to indoor air quality basics goes deeper on what the certifications measure.
