420 lb Hard-Bottom Dog Back Seat Extender with Seven-Layer Cover and Mesh Window – ROUWINNE

Hard-bottom dog back seat extender construction bridges the rear footwell to provide a broader platform for supervised road trips. ROUWINNE uses a reinforced 3.7-pound base plate listed to support up to 420 pounds, while a seven-layer Oxford cover combines PU and TPU barrier layers with non-slip dotted backing. The featured platform expands to about 53 inches wide and 24.8 inches deep when installed.

Full rear coverage and side sections help shield the bench, footwell edges and doors from fur, damp paws and routine abrasion. A zippered mesh window supports airflow and visibility, and two large pockets organize travel supplies. The platform can fold on one side for a passenger or compatible child seat. Choose Large for listed cars, mid-size SUVs and small trucks, or XL for full-size trucks and SUVs, after measuring the vehicle. Secure every attachment before travel and use a suitable pet restraint because the extender is not a crash-tested restraint system.
