Hard Bottom Dog Car Seat Extender

A Dog Car Seat Extender With a Hard Bottom, Not a Sling

This dog car seat extender puts a rigid support base across the gap between the rear seat cushion and the backs of the front seats, so the whole rear footwell becomes a flat platform. A waterproof quilted cover wraps the seat, the seat backs and the door panels, and the base takes the weight instead of sagging under it.

A Rigid Base Does Not Sag

• No sagging middle: the rigid base holds flat rather than dipping into the footwell the way a hammock does.
• Room to stretch out: the extended surface is wider than the seat cushion alone, so a big dog can lie full length.
• Covers what he can reach: the seat, the backs of the front seats and the door panels, against claws and mud.
• Seat belt openings: the car's own belts pass through the cover, so it stays on when a person sits back there.
• Mesh window and pockets: you can see him from the front, and his leash and bags live in the side panel.

Sized for a Dog That Stretches Out

The rated capacity is what separates this from a fabric hammock. The base spreads the load rather than concentrating it in the middle, which is why a large dog can stand up and turn round on it without the surface folding.

The Difference on the First Journey

Without a support base, a dog spends the drive finding his footing and slipping into the gap. With one he lies down once and stays there, which is the whole reason people buy a platform rather than a cover.

It Covers the Doors and Seat Backs Too

The side panels carry a mesh window so you can check on him from the driver's seat, and two pockets for the things that otherwise roll around the footwell.

Waterproof, and It Takes Claws

The quilted cover is layered so water does not pass through to the upholstery, and the surface resists the scratching and abrasion that finish an ordinary blanket in a season.

Installed in a Few Minutes, No Tools

Buckle the straps over the front and rear headrests, thread the seat belts through the openings, and tighten. Nothing is screwed or clipped to the car itself.

Size

One size, cut for a standard rear bench and adjustable at the straps, so it fits sedans, SUVs, pickups and vans. The dimension diagram in the gallery gives the laid-flat measurements if you want to check it against an unusually small back seat.

Specifications

• Weight capacity: Up to 280 lb (127 kg)
• Base: Rigid hard bottom that bridges the seat gap
• Cover: Waterproof quilted fabric, scratch resistant
• Protection: Back seat, front seat backs and door panels
• Fittings: Seat belt openings, pet safety belt, mesh window, side pockets

Safety note: clip the included pet belt to a properly fitted harness rather than a collar, since a collar can injure the neck in a sudden stop.

The Whole Back Seat Becomes His

There is no footwell left to slip into and nothing to brace against on the bends, so he lies down once and is still asleep when you park.
