It just fit in, was a bit worried about the assembly but it a fun project, just make sure you have a hammer and philips head screw driver (star as we call it) preferably a powered screw driver will be great will make your life way easy and your palms will thank you for it, you will need an extra pair of hands if your screw driver is not powered.
It quite easy to assemble, what you see on the pick is what you will get, a lot of storage no more visible remotes when not in use.
