This heated car seat cover was deemed The Best by the Hammacher Schlemmer Institute because it provided the most heat, was the easiest to use, and was the most comfortable. During evaluations, it reached an average of 88° F on low and 98.3° F on high—while lesser models only reached an average of 62.6° F and 87.6° F, respectively. It also provided the most consistent coverage by evenly distributing heat across its surface. Rated as the easiest model to use, it was simple to secure onto a car’s seat and had an easy to read, well labeled remote control. It also provided an ideal level of cushioning. Unlike other car seat covers tested, The Best unit came with a removable lumbar cushion and had a cooling function for hot days. It attaches to a seat back with hook-and-loop fasteners, has a tethered remote, and is powered via a vehicle’s 12V adapter or indoors via AC. 48" L x 21" W x 3" D. (41/2 lbs.)
