Frequently Asked Questions
How do I stop orthopedic foam from getting moldy on a porch?
Use a waterproof liner under a removable outer cover to prevent moisture reaching the foam, place the bed on an elevated or ventilated surface so air can circulate underneath, and wash the cover frequently. If foam gets wet, remove the cover and dry the foam thoroughly in sunlight or a dry, ventilated area as soon as possible.
Will a waterproof liner make the bed hot or uncomfortable?
A thin waterproof liner under a breathable outer cover usually has minimal impact on comfort. Choose breathable, quick-dry outer fabrics (polyester or mesh) and avoid thick plastic directly against your pet. Most reviewed beds combine a soft microfiber cover over the liner to keep the surface comfortable while still blocking moisture.
What’s the best way to remove odors from orthopedic foam?
Start by removing and machine-washing the outer cover per its care label. Wipe the waterproof liner with a mild detergent and allow it to air dry. For lingering odors, sprinkle baking soda on the dry cover and vacuum after an hour. Avoid saturating the foam; if the foam itself smells, let it air in sunlight and good airflow, or consider replacing the foam core if the odor persists after thorough drying and cleaning.
