No, you should not put a memory foam pillow in the dryer. Memory foam pillows are made of viscoelastic foam, which is sensitive to heat and can be easily damaged by high temperatures.
The high heat and tumbling action of the dryer can cause the memory foam to deform, lose its shape, or even melt. Additionally, memory foam can absorb moisture, and putting it in the dryer may not effectively remove the moisture and could potentially lead to mold or mildew growth inside the pillow.
If your memory foam pillow needs cleaning, it's best to follow the manufacturer's care instructions. Most memory foam pillows are spot-clean only and should not be submerged in water or placed in the dryer. To remove stains or odors, you can spot clean with a mild detergent and water, then allow the pillow to air dry in a well-ventilated area.
If your memory foam pillow is severely soiled and needs a more thorough cleaning, consider using a pillow protector or cover that can be removed and washed separately. This will help extend the life of your memory foam pillow and keep it in good condition for a longer time.
