No, TEMPUR foam inserts cannot be washed.

TEMPUR-Pedic says not to wash or submerge its TEMPUR material pillow inserts. If the pillow has a removable cover, wash the cover separately using the care instructions for that product.

The insert and cover are different

The foam insert is not treated like ordinary laundry. TEMPUR-Pedic says its material is sensitive to liquids and that its pillows are not washable. Soaking or putting the insert in a washing machine can damage it. Do not put the foam in a dryer or try to clean it by saturating it with water.

Some pillows have a removable cover. TEMPUR-Pedic's general guidance for its covers is cold water with mild detergent, followed by hanging the cover to dry. Check the sewn-in label first because covers and pillow models can differ.

If the insert needs attention

Remove the cover if the product is designed for that, and wash only the cover. For the insert, follow the instructions supplied with the exact model. If those instructions do not explain how to handle a spill or odor, contact the manufacturer rather than soaking the foam or applying an unapproved cleaner.

Scope

This answer is specific to TEMPUR-Pedic guidance. “Memory foam” describes many products, and care instructions vary by foam, cover, and construction. For another brand, use its care label and manual instead of applying TEMPUR's directions automatically.
