I love latex bedding. Our bed is latex. That being said I wanted to get a nice latex pillow so I ordered a kingsize medium. The density and firmness was just right. The pillow comes in a flame retardant cover, followed by a cotton zip case. Well I've had this pillow for a year and haven't put the cotton zip case through the wash since I just wash our linen pillow case that protects it. Today I decided to remove the cotton zip case and saw through the flame retardant cover (its a mesh) that the pillow is disintegrating. There are big tablespoon chunks missing and traveling around in the pillow case. This pillow hasn't been exposed to temperature extremes, just regular use. I'm really dissappointed. The good news is that at this point you can't feel the unevenness but at some point you would.
