Yes, Diono Radian's. I have two of the r120's on the 60% side and it gives JUST ENOUGH room to slide the 40% seat forward to get the 3rd row. The seat behind the driver has always been forward facing while the seat next to it (middle) has been both rear and forward facing. Both worked fine but there seemed to be just a bit more room to slide the seat forward when the middle seat was rear facing.
Looks like the r120 might not be available anymore though. I suspect the new model is the 3rx.
R100 replaced by 3r
R120 replaced by 3rx
RXT replaced by 3rxt
