How the extender, organiser and pet stair work
The extender fills the footwell gap beside the seat, and a stable embedded hollow board gives the surface its structure. When a dog lies down in the seat, the platform supports its feet.
The same unit serves as a car organizer and seat storage unit, and it can be placed in the trunk for storage. Outside the vehicle, the unit works as a pet stair that helps a dog get on or off the car.
Cleaning and folding the Oxford cloth extender
The 600D Oxford surface wipes clean, which is how dirt and mud come off it. A non-slip bottom keeps the unit in position on the seat.
When the extender is not in use, it folds away for storage, and the two handles help with lifting it in and out. It can also sit in the trunk between trips.
Does this seat extender fit my car and my dog?
How much weight does the extender hold?
The extender is built for pets up to 120 lbs.
Which vehicles does it go in?
Most cars, trucks and SUVs accommodate it, and the front seat area or the back seat are both places where it works.
What size is it when expanded?
Fully expanded it measures 20.1"L x 11.4"W x 14.2"H.
Can the storage area be divided?
An adjustable divider lets you assemble the unit into 3 or 4 storage spaces.
What to check before you buy
The seat extender fits most cars, trucks and SUVs, but the gap it fills varies from one vehicle to the next. Measure that gap before purchase so the expanded size of 20.1"L x 11.4"W x 14.2"H suits your seat.
Check the space beside the seat in the back and in the front before deciding where the extender goes.
