Adjustable pillows let you unzip and remove as much filling or as little fill as you like. People can keep the pillow full, take out half the fill, or take out the majority of the fill to make the pillow flat. This is a great feature that other types of pillows do not have. One of the major adjustable pillows is bamboo shredded memory foam pillow. Bamboo pillows have filling of memory foam. You can take out the memory foam as required.
Even though most people know memory foam doesn’t flatten out with use, they’re often confused about shredded memory foam, because it’s different, it’s shredded. However, the foam is absolutely the same as the one used in solid fill. So to answer your question, no, shredded memory foam pillows don’t go flat.
