We dont use a floor so bring your "camp slippers". We just find a nice gravelly area to setup on (Not hard where we go). Once the gravel is warmed up from the heat of the stove it helps keep the tent warm also.
I put a small strip of carpet by my bed so I have something to stand on when I change, thats it though.
