The modular pillow with nested cooling layers. Peel back the heat, reveal the cold. No AC required.
Inspired by matryoshka dolls, SnowNest uses phase-change material to prevent night sweats and overheating. Each layer peels back to reveal a fresh cool layer beneath—customize both temperature AND pillow height.
You insert the pillow and feel an immediate cooling wave cascade around your head and neck like fresh snow. Then you realize: when this layer warms up, you just unzip it to reveal another perfectly cool layer underneath. You finally sleep through the night for the first time in years—while your partner marvels at not being woken up by pillow-flipping anymore.
