re: Attic flooring questions

The joists are 2x6 running from the existing bedroom into the attic. The end game is to have the small nook there for her to use and after she leaves it will be attic storage again. We were going to put a desk in the room but already have a bed, nightstand, chest of drawers, and another long chest of drawers with a hutch and shelves on top. Plus a chair in the corner with an ottoman in front of it. Didn’t want it to be too busy even though the room is quite large. House was built in the late 60s and didn’t have a true master until we did renovations about 5-6 years ago. This was the largest room in the house and the one we slept in for years. Converted a den into a master bath with claw foot tub, walk in shower, dual sink vanity and walk in closet. After that was complete we moved downstairs and our son used the room. He’s moving to her old room and she’s moved into this one as of this past weekend. The full size door replacing the short door will also help down the line to easily access storage.
