I have a child seat installed in the center position. Due to the recessed seat belt receptacle, it's almost impossible to have a passenger sit on either side to the seat. To fix this, I went to the dealer and bought a seat belt extender. Note that the extender for the CX-5 only fits the front seats - the receptacle in the back and the front is not the same. Inspecting other cars on the lot, we noted that the Mazda 3 has the same receptacle in the front as the CX-5 in the back, so I ordered that instead and it works. Unfortunately it's quite expensive at around $45.
