Large Dog Car Seat and Half-Backseat Extender with Hard Bottom, Mesh Sides and Leash Slot – Instraella

Large dog car seat space turns half of a rear bench into a supported travel area while leaving an adjacent passenger position available. Instraella uses a hard-bottom frame with 360-degree wraparound sides, helping a dog rest on a broader platform during short drives or longer road trips.

The 27.5-by-21.6-by-20-inch enclosure supports pets up to seventy pounds and can install on the left, right or middle of a compatible rear seat. Dual-layer waterproof Oxford fabric resists dirt, scratches, wet paws and loose hair, while mesh windows on both sides support airflow and visibility. A nonslip base, seat anchor, rear strap and tightly fitted connector tubes stabilize the structure. The integrated slot accepts the dog’s existing safety leash, and a leash-compatible buckle is attached to the seat-back strap. Choose Black or Grey in Large. Insert both tubes fully, close every surrounding zipper to the top and tuck the anchor into the seat gap before travel. Confirm the enclosure dimensions against the vehicle and dog, attach a suitable automotive pet restraint to a harness rather than a collar, and never use the seat as a substitute for responsible driving or supervision.
