QuiltLoft™ Memory Foam

CoolFeel® Plus Fabric

• Fabric treated with cooling performance technology pairs with a breathable wool layer to help create a refreshing, cool-to-the-touch feel as you settle in—so you stay comfortable from the moment you lie down.

Responsibly crafted

Care

• To protect your mattress from stains and spills, we highly recommend using a mattress protector; This will also help with the overall health and lifespan of your mattress.
• We do not recommend applying liquids to the product; Applying liquids may stain the fabric and make the soiled area worse; Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.
• We suggest applying baking soda to the soiled area, let stand about 15 minutes, vacuum, and repeat as needed; Air the product out as much as possible.
