Rear seat depth difference CrewMax versus Double Cab

Hello:
I can find specs for the rear seat in terms of head, hip, leg and shoulder room, but does anyone know if there's a difference in the actual seat dimensions, particularly the bottom cushion depth? Does the CrewMax have a deeper seat than the Double Cab, or are they exactly the same seat with just more leg room in the Crew Max? Thanks!

 

My DC seat depth is about 18 inches. It’s tough to get an exact measurement because the seat back doesn’t meet the seat.

 

No sir. They are not the same rear seats. They both have different tops and bottoms

 

Thanks @Plumpy33 & @WestexSBK ! I found a great photo comparison on another, older thread here that shows photo comparisons. https://www.tundras.com/threads/double-cab-vs-crewmax-rear-seats.70008/
