Hypoallergenic nursery bedding: what to check

Infant sleep guidance comes before any allergy question. The American Academy of Pediatrics (AAP) and the US Consumer Product Safety Commission (CPSC) each describe what belongs in a crib, and the answer is short. This page explains how to read “hypoallergenic” against that guidance. Allergy-related choices do not override it. We research from documents and have not tested products ourselves.

What the AAP and CPSC say about the crib

The AAP’s HealthyChildren.org page says a firm surface “shouldn’t indent when your baby is lying on it” and that the mattress should fit the crib snugly. It says: “Use a fitted sheet only—nothing else should be in the crib with your baby.” It says soft objects and loose bedding “can increase your baby’s risk of entrapment, suffocation or strangulation”, and lists pillows and pillow-like toys, quilts, comforters, mattress toppers, non-fitted sheets and bumper pads. For warmth, it points to layers of clothing or a wearable blanket instead of loose blankets.

The CPSC’s Crib Safety Tips page agrees in substance. It says to place the baby on the back in a crib “with a firm, tight-fitting mattress”, not to put pillows, quilts, comforters, sheepskins, pillow-like bumper pads or pillow-like stuffed toys in the crib, and to use “only a fitted bottom sheet specifically made for crib use”. It says to consider a sleeper instead of a blanket, and if a blanket is used, to tuck a thin one around the mattress, covering the baby only as high as the chest.

We are reporting those statements, not extending them. Questions such as how to dress a baby for a cold room, or whether a medical condition changes any of this, belong with your paediatrician.

What this means for “hypoallergenic” shopping

Most bedding that is marketed with the word is made for adult beds: pillows, comforters, toppers and duvets. Those are exactly the items both organisations list as things to keep out of a baby’s crib. Our roundups on pillows, comforters, duvets and mattress toppers are for older children and adults, not for an infant’s sleep space.

That leaves the sheet and the mattress as the items where an allergy-minded choice is even possible. Our guide on what “hypoallergenic” means covers why the word is a marketing claim rather than a legal standard. Our page on the allergy-certified bedding label and the Asthma and Allergy Friendly certification explain the certification marks you may see on adult bedding. We did not find a source saying those marks apply to infant sleep products, so we do not say they do.

The textile label worth knowing

OEKO-TEX describes STANDARD 100 as “a label for textiles tested for harmful substances”, and says every item bearing it has passed those tests, with a list of over 1,000 substances. It says the requirements get stricter as skin contact becomes more intensive and skin more sensitive, and it names a product class for babies and children up to 3 years, which “has the strictest requirements and limit values”. The page gives a label check: a QR code or certificate number can be entered into its Label Check to confirm validity. Our OEKO-TEX explainer goes further.

This is a harmful-substances label, not a statement about allergy. It cannot tell you that a sheet will not bother a given baby, and we do not claim it.

Dust mites in the nursery

NIEHS says dust mites can live in mattresses and bedding, that they cannot be completely eliminated however clean a home is, and that their numbers can be reduced. Its list for adults and households includes keeping humidity at or below 50 percent, encasing mattresses and pillows in allergen-impermeable covers, and washing bedding weekly in 130 to 140 degree Fahrenheit water. Those lines are general, not infant guidance. A crib sheet is washable, but we did not find a source giving a wash temperature for infant sheets, so check the care label and ask your paediatrician. See our guides on dust mites in bedding and a mite-proof cover’s pore size.

The strongest study we read is a randomised, placebo-controlled trial (PMID 12153962) in 1,282 allergic pregnant women’s children. Covers went on the child’s and the parents’ mattresses. It reported a lower prevalence of night cough in the second year of life with active covers (adjusted odds ratio 0.65; 95% CI 0.4 to 1.0), and no effect on other respiratory symptoms, atopic dermatitis or atopic sensitisation in the first 2 years. A 2025 systematic review (PMID 40774466) found only three high-quality studies among 54 on home interventions for childhood asthma. The abstracts do not discuss crib safety, and neither we nor those abstracts say a cover is suitable for a crib. Ask the mattress maker and a paediatrician.

Washing and the rest of the room

Our pages on laundry detergent, sheets and the laundry routine cover washing questions, and the hypoallergenic bedroom guide covers the wider room. Those pages are written for general use. Check any item you take from them against the AAP and CPSC statements above.

Where a clinician comes in

If your baby has eczema, a diagnosed allergy or breathing symptoms, the decisions about bedding, washing and the room are medical ones. An allergy or dermatology society, or your paediatrician, can advise on them. No product or label described on this page substitutes for that advice.
