Do these covers fit bucket seats and bench seats, or just one type?

Fit varies by seat shape and contour. Your vehicle's seat design determines how snugly they wrap. Test-fit before committing to permanent placement, especially if your seats have unusual bolstering or headrests.

Will these stay in place while driving, or do they slide around?

Slip-on covers rely on tension and friction to hold position. If your seats are very smooth or heavily contoured, you may need adhesive strips or fasteners to keep them from shifting—mounting method is up to you.

Can I remove and wash these covers?
