Posh Pile mats feature: - A thermoplastic rubber backing on the 5TH Avenue mats; something Tom could not find even in Lexus OEM mats. - Fully sewn edges instead of inexpensive taped edges like on most aftermarket mats. - Woven Nylon heel pads instead of less luxurious vinyl or plastic. - Special universal sizing designed to fit the majority of cars on today's roads. - Stay Tuned has an innovative weight saving hook and loop anti-drift backing, normally only found on factory mats from Japan.
