Cool Seat Pad Passive Cooling Firm Chair Cushion Now you can always have the coolest seat in the house--everywhere you go! The passive cooling in these pads is activated by your body heat, so it keeps you cool with no energy and no noise whatsoever. They are also safe to use long term; they will never become so cold as to be dangerous--just pleasantly cool. You can even use them in the car or your favorite window seat: simply turn the reflective silver side up when it isn't in use so that the sun doesn't overheat and damage the minerals inside. Perfect for use at home, in the office, during road trips--anywhere you're in the hot seat! Never refrigerate or freeze Flexible design to fit any seat Flip over when not being used to preserve coolness Fun pirate and dinosaur pattern Dimensions: 17.3L x 15.7W x 0.5H (44cm x 40cm x 1cm) 1pc
