aPillow are proud to have been allowed to use the Folding Pillow Patent. This Folding Pillow pillow concept was developed for hygiene purposes as moisture and bacteria build-up can easily be aired/washed out. This is particularly beneficial for those who suffer from symptoms of asthma and allergies. Folded they fit a standard pillowcase. Roll one panel before folding provides neck support. A very unique pillow indeed.
