WHY HARD-BOTTOM?

A soft hammock covers the seat. Deck changes how the space can be used.

Dogs do not care that the footwell was designed for human legs. A rigid platform turns that broken-up rear cabin into a more continuous place to stand, turn and settle.

01

Bridge the gap

The platform extends the usable surface beyond the narrow rear bench.

02

Protect the cabin

Waterproof multi-layer construction and raised side panels help isolate upholstery and door trim from everyday dog mess.

03

Keep travel organized

Mesh visibility and built-in storage keep the dog’s travel zone more deliberate and less cluttered.

TWO DECKS. ONE EASY DECISION.

Start at $99.95. Upgrade to Signature for only $10.00 more.

Both use an 8-layer hard-bottom concept. Essential wins on value. Signature adds the 5 mm virgin HDPE board, higher supplier-rated load and premium storage setup.

BEFORE YOU BUY

Questions people should ask before clicking Add to Cart.

Is Signature worth the extra $10.00?

Choose Signature if the 5 mm virgin HDPE board, 450 lb supplier-rated capacity, premium cushioning and two oversized pockets matter to you. Essential remains the better-value choice if your priority is the core hard-bottom platform and waterproof cabin protection.

Are the 400 lb and 450 lb ratings crash-safety ratings?

No. They are supplier-provided platform load ratings, not crash-test certifications. Deck does not replace a dog harness, seat belt or other appropriate restraint.

Is Deck waterproof?

Both supplier specifications list PU and TPU waterproof layers. The products are intended to protect the cabin from ordinary spills, wet paws and travel mess.

Will Deck fit every car or SUV?

No honest product can promise that. Essential is listed at 52 in wide and Signature at 50.4 in, so measure your rear cabin and use the Fit Guide before ordering.

What does “+45% more space” mean?

That is a supplier claim for Signature based on extending usable surface over the rear footwell. It is not a guarantee that every vehicle gains exactly 45%.

Can Essential be cleaned easily?

The Essential supplier lists vacuuming, wiping, rinsing and machine washing as supported cleaning methods. Always follow the care instructions supplied with the final product.

THE BACK SEAT, RECONSIDERED

One car. One dog. A lot more usable space.

Choose Essential for maximum value or spend $10.00 more for the premium Signature build.
