Twin XL Gel Memory Foam Mattress Topper
Dorm mattresses are vinyl stretched over a spring board. Three inches of foam is the highest-impact thing you can add to a room you did not choose, and it rolls up small enough to survive move-out.
Compact Air Circulator Fan
Most dorms have no air conditioning and radiators you cannot turn off. What actually helps is moving the air across the room rather than blasting it at your face, which is why a circulator beats a bigger fan.

Adjustable Bed Risers
Raising the bed turns dead floor space into the only real storage a dorm gives you. Measure first: most housing contracts cap how high you are allowed to go, and they do check.
Under-Bed Fabric Storage Bins
These go under the risers. Off-season clothes disappear into them in September and you genuinely forget they exist until the week you need a coat.
