We can see concrete blocks, gym mattresses, plastic crates, inflatable objects with tapes and a few things on the floor. We can see papers with text, a clock, bags, hanging objects and some objects on the walls. We can see ceiling lights and the objects in the racks. We can see windows, window blinds and other things. Through these window blinds, we can see poles in the background.
