The outer quilted layer on an Avocado Natural Latex Topper features a brass zipper, which is intended to make it easy to readjust the internal 2-inch natural latex layer, in the event that is needs to be repositioned.
This zipper also makes it possible to remove the outer ticking layer entirely. Even so, we do not recommend washing this outer layer in a washing machine. It's very bulky and the cotton and canvas base layers may shrink.
Instead, it is best to spot clean it with natural cleaners.
