Quick Answer
Whether a mattress topper can be washed depends on its material and construction. Check the care label first. Many foam toppers should not be machine-washed or soaked; spot-clean them instead. Some fabric or fiberfill toppers may be washable according to their label.
How to Wash Mattress Topper
Remove the topper cover if it is designed to come off, and wash it separately according to its care label. Do not assume the topper itself is washable. Foam, memory foam, latex, and toppers with bonded layers can be damaged by machine agitation or soaking; spot-clean these with a small amount of mild detergent and a damp cloth, then blot with a clean cloth. For washable fiberfill or other fabric toppers, follow the item's label for cycle, temperature, and detergent. If there is no label, check the manufacturer's instructions before washing.
How to Dry Mattress Topper
Air-dry a spot-cleaned topper thoroughly in a well-ventilated area before putting it back on the bed. Avoid wringing or twisting foam. Use a tumble dryer only if the care label explicitly allows it; heat can damage foam, adhesives, or other materials. Make sure the topper is completely dry to help prevent mildew.
What to Avoid
Do not put a topper in the washing machine or dryer unless its label permits it. Avoid soaking foam, using hot water or high heat, wringing the topper, and returning it to the bed while damp.
Important Warnings
Mattress toppers vary widely in materials and construction, so care instructions are not universal. Keep foam and other water-sensitive materials from becoming saturated. Follow the care label or manufacturer instructions whenever available.
