Review on Husky Liners 98921 Weatherbeater Front & 2nd Seat Floor Mats for 2012-14 Toyota Prius Two/Three/Four/Five – Black by Carlos Abood

Trust the manufacturer's description: It's 12-15, not 10-15. It fits 10-12 Prii but the rider's mounting hooks are in a slightly different position so it doesn't fit the rider mat exactly. You can either punch your own holes (I highly recommend installing grommets if you do) or just ignore the slight bulge. These mats are quite thin and light (the latter is good for high fuel consumption vehicles) but very hard. You will have almost no trouble folding them or otherwise losing their shape. Bonus: They significantly reduce street noise.
