Frequently Asked Questions
Will these protect my car from urine or heavy spills?
Most of the picks use a waterproof membrane or multi-layer construction that resists small accidents and spills. Hard-bottom extenders and premium layered covers provide the best barrier. For heavier liquid exposure, look for multi-layer 600D fabric with a confirmed internal waterproof layer and follow care instructions to maintain the membrane.
How do I know which size will fit my vehicle?
Measure your backseat width (door-to-door) and depth (seatback to seat edge). Compare those measurements to the product dimensions — extenders list length/width/depth while throws list overall blanket size. If your car has bucket seats or a small bench, choose a more compact cover or a throw; full-size extenders are better for SUVs and trucks.
Are these easy to clean after road naps or muddy trips?
Yes — most models are machine washable or have removable elements (like the bottom plate) that let you wash covers easily. Quilted and sherpa throws typically machine wash; hard-bottom extenders often require removing the supporting boards before laundering. Always follow the manufacturer’s care instructions to avoid damaging waterproof membranes.
