Untreated Cotton/Linen Gliders
Look for brands that explicitly guarantee their fabrics are free from DWR (Durable Water Repellent) or PFAS treatments. Removable, washable slipcovers are the safest "stain-resistance."
PFAS (Forever Chemicals) in Nursery Furniture & Gliders
If a nursery glider is marketed as "stain-resistant," it is almost certainly coated in PFAS. Here is why you need to avoid them.

The quick answer
PFAS (per- and polyfluoroalkyl substances) are synthetic "forever chemicals" used aggressively in nursery furniture, specifically nursing gliders, rugs, and mattresses, to make them water-repellent and stain-resistant. These chemicals do not break down in nature or in the human body. They are linked to kidney cancer, thyroid disruption, and lowered vaccine efficacy in children. To avoid them, you must reject any furniture marketed as "Stain-Resistant," "Performance Fabric," or "Water-Repellent" unless the brand explicitly guarantees it uses PFAS-free technology.

Editor's note. This analysis tracks the migration of PFAS from textiles into household dust and human blood serum.
01
The Lure of "Performance Fabric"
"Performance Fabric" marketing on nursery furniture promises that the inevitable fluids of new parenthood (breast milk, spit-up, formula, blowouts) magically bead up and roll off. The stain-repellent chemistry behind it has a long history: the original Scotchgard formulation was made directly from PFOS, a highly toxic PFAS, and even after the formula changed in the early 2000s, scientists argue the replacement PFAS chemistries are just as toxic.
The magic trick is achieved by spraying the fabric with PFAS. The carbon-fluorine bond in these chemicals is one of the strongest in organic chemistry, making them incredibly resistant to breaking down (hence "forever chemicals").
As you sit on the chair, the physical friction causes the microscopic PFAS particles to flake off into the air and mix into house dust. Because your baby will eventually crawl on the floor, they ingest this PFAS-laden dust daily.
Stain-resistant performance fabric is a trade: a coffee stain on your chair for a forever chemical in your child's bloodstream.
Renee Says
In short
- PFAS coatings are what make "Stain-Resistant" fabric work.
- Friction causes the chemicals to flake into house dust.
- Infants ingest the dust via hand-to-mouth behavior.

What the Science Says
The toxicological data on PFAS is grim. Because the body cannot break down the carbon-fluorine bond, the chemicals bioaccumulate in the liver and blood over a lifetime.
In children, high levels of PFAS exposure have been strongly linked to metabolic disruptions, altered thyroid function, and a severely suppressed immune system (specifically, a lowered antibody response to childhood vaccines). The EPA recently released unprecedented health advisories indicating that some PFAS chemicals are unsafe to drink at literally *any* detectable level: a safe threshold of effectively zero.
The practical answer on textiles is third-party testing: certifications like OEKO-TEX Standard 100 explicitly test for and ban the presence of PFAS chemicals in the final fabric.
PFAS bioaccumulate in children's blood and liver, and EPA health advisories deem some PFAS chemicals unsafe to drink at any detectable level.
In short
- Bioaccumulates in blood and liver.
- Lowers vaccine efficacy in young children.
- EPA deems some PFAS unsafe at any concentration.
The bottom line
A stained chair is annoying; an endocrine-disrupting chemical is dangerous. Buy untreated, natural fabrics (like cotton or wool blends) or opt for OEKO-TEX certified fabrics. When the baby spits up, clean it the old-fashioned way: with soap and water.

Frequently asked questions
Common questions about toxicology: furniture, answered by our research team.
QAre PFAS the same as Scotchgard?
PFAS and Scotchgard are historically the same chemistry: the original Scotchgard formulation was made directly from PFOS (a highly toxic PFAS). The formula was changed in the early 2000s to use a "newer" generation of PFAS chemistries, but scientists argue these new replacements are just as toxic.
QHow do I clean an untreated chair?
Cleaning an untreated chair is easiest with a Little Green Machine or similar spot-cleaner plus a safe, enzyme-based stain remover (like Puracy). Better yet, use a washable blanket draped over the chair during the spit-up months.
