Kids Allergy Bedding
Children spend more hours in bed than almost anywhere else, and a young, developing immune system can react more strongly to the dust mite allergens that build up in an ordinary mattress and pillow over time. AllergyStore.com's kids allergy bedding is sized for twin and twin XL beds, the sizes most children sleep on from their first "big kid bed" through the teen years, so parents do not have to guess which of our regular encasements will fit.
Every mattress and pillow cover on this page traps 99.95% of common household allergens, based on the AAAAI and ACAAI Joint Practice Parameter on dust mite exposure control, which identifies allergen-proof encasements as the single most effective environmental control step a family can take. These are the same encasement designs we have sold to allergic and asthmatic households since 1989, just in the sizes kids actually sleep on.
Why Kids Need Their Own Allergy Bedding
Growing bodies, bigger reactions
Children's respiratory systems are still developing, which is part of why pediatric allergists frequently recommend dust mite covers as a first-line, non-drug step for kids with allergy or asthma symptoms, alongside whatever a family's own doctor recommends for their child specifically.
Bunk beds and twin mattresses take more wear
Jumping, spilled snacks, and the occasional accident mean a child's mattress and pillow need protection that holds up to more activity, not less. That is why several of the covers below combine allergen protection with a waterproof or bed-bug-rated barrier, useful for bunk beds, sleepovers, and younger kids who are still outgrowing nighttime accidents.
One size does not fit all bedrooms
A twin or twin XL mattress needs a cover built for that size, not a queen or king cover with extra fabric bunched at the corners. Every product below is available in twin and twin XL, and several come in a full size too for kids who have already moved to a bigger bed.

Frequently Asked Questions
What size mattress cover does my child need?
Most children's beds are twin (39" x 75") or twin XL (39" x 80", common in bunk beds and some day beds). Every mattress cover on this page is available in both sizes, plus full size for kids who have moved to a bigger bed. If you are not sure which size fits your child's mattress, measure the mattress itself rather than the bed frame, since mattress depth (how many inches thick) also affects which cover fits best.
Are these safe for children with sensitive skin?
The 100% cotton and organic cotton options are woven from chemical-free, naturally soft fabric, and several of the covers on this page are independently OEKO-TEX Standard 100 certified, meaning they have been tested for harmful substances. As always, if your child has a diagnosed skin condition or allergy, check with your child's doctor before switching bedding.
Can these covers help with bedwetting too?
The Bedbug Solution® Elite Mattress Protector and several of the other covers on this page include a waterproof barrier in addition to allergen protection, which many parents find useful for younger kids who are still outgrowing nighttime accidents.
Do you have covers for cribs and toddler beds?
Yes. Crib and toddler-size allergy bedding lives on our separate Crib Covers & Sheets collection, along with our guide on safe sleep and dust mite protection for baby's crib. This page is sized for twin and twin XL kids' beds.
How do I wash a kids allergy mattress cover?
All of our cotton and organic cotton covers are machine washable. See our full dust mite cover washing instructions for wash temperature and drying guidance, since washing at the right temperature is part of what keeps a cover effective against dust mites over time.
Do these covers come with a warranty?
Yes. Every mattress and pillow cover on this page carries our AllergyCare™ Limited Lifetime Warranty.
