2009 base model seat replacements available?

Didn't see a board for interior questions..........
This 4 Cyl base model with auto trans has the full bench seat which isn't very comfy, and also has no arm rest, which I miss a lot. The lever for access behind the seat is crude, and the entire backrest must move forward to get at stuff back there. All that to say,..... can the other Tacoma model seats fit in place of this one? I have been looking in other trucks, and there are some nice split bench seats out there. Will they bolt in?

 

Usually only seats from same generation will bolt directly with little mods such as seat airbag sensor.
