## Questions & Answers

A: I don’t know but fits my Jeep Grand Cherokee Overland

**Q: Where should the buckle/straps be placed to secure in vehicle?**
A: buckles would not work w my seat either. i like the cushion though!

**Q: Is the cover removable to launder?**
A: Mine has a removable cover, but the zipper broke off and tore from the seams when I washed it on the delicate setting. Very annoying.
