An oak window seat - Part 2

Installation day for the oak window seat.  This one starts out pretty standard with building a platform on the floor and covering it with mdf for a base.  I've then built a small "wall" with 2x4's and applied the face that I made up and prestained in the shop.  Scribing is a critical skill here, because you want everything as tight as possible to the walls. Even though this house is only 3 years old, the walls are not totally square.
