Nope, it's easy. Need a few tools - socket and a small extension (or a spanner and some patience). The seat belt bolt can be a POA, as can be the belt height tensioner, but other than that....
...just have at it. Motors are pretty well up there. Just start with the seat at it's highest/furthest forward (to remove back bolts), then slide it back and down, push forward, and pop it out.
