The Luxury insert is a 23” x 23” custom made 64 oz gel insert. It provides comfort and substantial fullness and will rest steady wherever you place it. Best used indoors, it can be a terrific option for outdoor use as well. The weight of the pillow can keep it from blowing around easily. It is recommended that all pillows be brought indoors during inclement weather. If the pillow cover and insert get wet – separate and air dry.
