In a Corolla 96, it fit perfectly. I can rest my elbow on it when it's empty. I highly recommend it without hesitation.

I have it for about a month. The truth is that it helped me in the car and it doesn't bother the seatbelt too much. It hasn't presented any problem although it's early. I only use it from the passenger side.
Attention to the pieces.

Really useless invention! It is advertised as a universal, well-designed application to serve as a "small object organizer" but if you have a modern semi-bucket seat, it doesn't fit in any position between the seat and the horizontal console. But even if you find a makeshift way to secure it, its length has not been considered and it either gets in the way of the handbrake lever or the gear selector. I literally wasted €31 on it....
