UNICITII Car Seat Extender for Large Dogs—120 lb Capacity, Front or Back Seat Organizer

Meet the UNICITII Car Seat Extender, a versatile upgrade designed for large dogs and busy households. It expands usable space in the back seat or up front, letting your furry companion settle in without crowding the cabin.

Expanded space for comfort

Designed for dogs up to 120 lbs, this extender offers a stable, roomy surface when your pet lies down. The fully expanded footprint measures 20.1 inches long, 11.4 inches wide, and 14.2 inches high, and it fits most cars, trucks, and SUVs. Before purchase, please measure the gap to ensure a good match with your vehicle.

In practice, the extender helps your dog relax during drives, reducing perceived space constraints and encouraging a calm, upright view of the road. This can be especially helpful on long trips or busy city commutes.

• Capacity and fit: supports pets up to 120 lbs with a low-profile footprint in many vehicle types
• Dimensions: 20.1 L x 11.4 W x 14.2 H inches for ample room to stretch
• Material and care: 600D scratch-resistant Oxford fabric that’s easy to wipe clean
• Non-slip base: bottom designed to stay in place while you drive

Secure travel and easy organization

Beyond space, the extender acts as a travel anchor, helping your dog’s feet rest comfortably and reducing movement during sharp turns and quick stops. It also creates a clear line of sight to the outdoors, which many dogs find stimulating and reassuring. For tidy trips, an integrated divider can be reconfigured into 3 or 4 storage sections to keep leashes, treats, toys, and blankets neatly in reach.

• Three or four-compartment divider keeps items from rolling or tipping
• Removable or reconfigurable layout to match your pet’s needs
• Foldable when not in use for compact storage

Versatile design for more than one use

This product doubles as a car organizer. Use it to fill gaps with food, blankets, and pet toys, or place it in the trunk to hold essentials on longer trips. It can also serve as a pet stair for getting on or off the car, helping your dog access elevated seats with confidence.

• Car organizer that can fill with essentials
• Can be placed in the trunk for additional storage options
• Pet stair functionality supports easy in-and-out access

Design and durability you can count on

Crafted from 600D scratch-resistant Oxford fabric, the extender is designed for easy cleaning after muddy paws and accidental spills. A lid, two handy handles, and a stable embedded hollow board contribute to a sturdy feel, while the non-slip bottom enhances safety during movement. The unit folds away neatly when you don’t need it, helping you reclaim cabin space quickly.

Note: Always measure the gap and verify compatibility with your vehicle before purchasing to ensure a good fit and smooth operation on the road.
