Pilo redefines the shape, texture and function of a pillow. Its shape resembles that of a stone, although the pillow, filled with so-called shape-memory polymer (memory foam), feels soft. Manufactured using ergonomic data, Pilo offers pressure relief for the nape of the neck. A special feature is the accompanying Dream Cloud app: a built-in, invisible speaker that works with low output impedance and without an external power source, creates gentle ambient background sound.
