On my Micra with the Vinyl door trims, you just pull in a circle around the edges, moving inwards and inwards until it's all loose. Remove the window winder and door handle and you're away. However, if you have a higher range model (Mine IS only an L spec), then I don't know. I gave up trying to get them off of an SGL model where my new seats came from, so it's an un-noticable mismatch.
