Query: Stron chemical odor

When I opened the shipping carton I was hit by a strong chemical odor. If you have small children you might want to leave these outside for a year or two untill the ordor dissapates. Also the rear mats are tiny. I had to use them in conjunction with the old mats to covetr the rear. If I did not have to pay for shipping I would have send them back
