Yes — but only when you need it to be. Our ParaTherm technology runs through the layers of the Parallel pillow to keep you at the perfect temperature, all night long and year-round. Our outer cover's TENCEL fibers have a temperature-neutral touch that is never too cool or too warm. It is treated with our plant-based Move+Cool treatment that maximizes the cover’s natural wicking, heat dissipation and evaporation qualities. And our hybrid inner fill is a blend of downy, hypoallergenic fibres and precision-cut gel visco foam enabling twice the airflow of conventional foam fills. So the Parallel Pillow is much MORE than a cooling pillow. It's a complete thermal regulation system inside and out, designed to deliver unmatched comfort! Just right, all night.
