Bedding is the category where students most often over-pack or buy too early. Rooms range from a bare cot to a fully made bed, so measure first and buy second. The types below cover a cot that needs a mattress, sheets that fit a narrow bed, and nights that are colder or buggier than you expected.
Single-bed mattress or topper
Some rooms come with only a bare cot or a thin, well-used mattress. A foldable mattress, or a topper over the existing one, can make the bed usable.
Check before you buy
Measure the cot (length and width) and buy to that size rather than a generic "single" label.
Foldable or roll-packed types are easier to carry on a train or bus.
A removable, washable cover is worth having in a shared room.
Read the listed thickness, material and the seller’s return terms before ordering.
Skip or avoid
Buying before you have seen the room; it may already have a mattress.
A mattress wider than the cot, which will sag over the edge.
