Product Description

More Room. Safer Rides. Less Mess.

Turn one side of your back seat into a secure, comfortable space for your dog without taking over the entire rear row.

The Petkera™ Single Back Seat Extender features a reinforced hard-bottom platform that bridges the rear-seat footwell, giving your pup more usable space while helping prevent slips and falls. Waterproof, tear-resistant materials also help protect your interior from scratches, dirt, fur, and messes.

Its single-seat design leaves the rest of your back seat available for passengers — ideal for everyday drives, family trips, and longer adventures.

Reinforced Hard-Bottom Support 

Give your dog a stable surface instead of an open rear footwell. The reinforced structure supports up to 110 lbs, creating more usable space for sitting, lying down, and relaxing during the ride

 Protects Your Car Interior 

The waterproof, tear-resistant construction helps shield your seats from muddy paws, fur, scratches, and everyday messes. High side panels add extra coverage while keeping your pup's space contained.

 Half the Seat. Full Flexibility. 


Unlike full-width dog hammocks, Petkera™ uses only part of your back seat. Your dog gets a dedicated travel space while the remaining seat stays available for another passenger

Testimonials

    Finally, my dog has room to relax.

    My dog used to slide toward the floor whenever I had to brake. The hard bottom gives him a much more stable area to sit or lie down. I also like that it only takes up one side of the back seat. I can still have someone sitting next to him.

    Perfect for road trips.

    I wanted something more supportive than a regular hammock-style seat cover and this was exactly what I needed. It gives my dog a nice flat area instead of leaving the footwell open. Setup was straightforward and it feels sturdy once installed.

    My back seat stays so much cleaner.

    My dog loves getting muddy at the park, so protecting the seats was a big reason I bought this. Hair and dirt stay contained and cleanup is much easier afterward. The high sides are also great for keeping him in his own space.

    Love the single-seat design.

    Most dog covers I looked at took over my entire back seat. This one gives my dog his own roomy section while still leaving space for a passenger. That's exactly what I needed for family trips.
