Hard-bottom dog back seat extender panels bridge the rear footwell to create a broader platform for supervised vehicle trips. Chumajor combines three honeycomb boards with a six-layer cover made from 600D Oxford fabric, PP cotton fill and non-slip backing. The assembled platform is listed to support up to 400 pounds when correctly installed, while extended side flaps help cover the rear bench and door areas from fur and everyday dirt.

A mesh viewing window supports airflow and lets a dog see the front area, while the storage pocket keeps small travel items together. Seat anchors, four headrest straps and two side-flap straps help hold the cover in position, and openings remain available for compatible pet restraints or child-seat access. Choose the Large version for listed pickup trucks, cars and mid-size SUVs, or the XL version for listed full-size trucks and SUVs; measure the vehicle’s rear seating area before ordering. Remove all honeycomb boards before machine washing the fabric cover. No seat cover replaces a suitable pet restraint or careful driving.

Frequently Asked Questions

Which Chumajor extender size fits my vehicle?

Measure the rear seating area and compare it with the selected size; Large is listed for cars, pickup trucks and mid-size SUVs, while XL targets full-size trucks and SUVs.

How much weight can the hard-bottom platform support?

The correctly assembled three-board platform is listed for loads up to 400 pounds, but it should still be checked for stable installation before every trip.

Can the dog seat cover be machine washed?

Yes. Remove every honeycomb board first, place only the fabric cover in a laundry bag and follow the care directions.

Does the extender replace a pet restraint?

No. Use an appropriate vehicle restraint through the provided access openings and drive carefully; the platform mainly expands and covers the rear-seat area.
