cargo liner
EXCELLENT fitment...   awesome quality and sweet price
go buy one 
 
 
OH and i am not associated with these guys.  I just bought 2 liners, one for my dads 04 sunfire, and one for my 03 cav.  AND my woman bought one for her 06 rav 4.  ALL fit perfectly.
 
Do they have a hard bottom? Or are they just material?
 
 
It is not a cloth material if that is what you mean.
The material appears to be a  thick dense foam with a flexible plastic top layer....  It feels quite durable, yet VERY light weight.  it bends without cracking.... and goes back to its orignal position.    I hope that answered your question  
 
 
yup...
Im gonna get one for my car as soon as i get some extra cash.
 
 
That guy is making a steal on this item, prob cost him about 10 bucks per one he makes.
 
 
still a good deal for someone that doesnt know how to make one
