WHAT IS A GUSSET AND WHY DOES THE CASPER PILLOW HAVE ONE?

A gusset is an extra piece of material that helps expand or give structure to a pillow. It creates a side panel, in addition to a top and bottom. To get the most out of our innovative double layer construction, Casper chose to include a gusset in the pillow design. Since the filling has more space to move around, the pillow feels consistently comfortable no matter how you’re sleeping on it.
