In Season 1 the bedroom layout was slightly different. The Room had a drum set instead of a bed. The window was an octagon with a grid instead of a circle. The door was facing front instead of being on the side. There was a couch where Josh slept. There was also a shelf on the right side of the door. However on Seasons 2, 3 and 4, the bedroom layout was changed without any explanation of how or why it changed.
On Season 2, 3 and 4 the set had a circle window. It also had a bed which belongs to Josh. The door was moved to the right. Half of the room had a taller floor and the Milencollin Home from home poster was on the upper wall and there were books on the new shelf in the wall taking place of the old shelf in the Season 1 version.
