An accommodation device includes a seat assembly, at least one flexible adjustment strap and an accommodating cavity having a bearing portion and a flexible circumferential surrounding portion. The accommodating cavity is rotatable between a lying state and a sitting state. When in the sitting state, a side of the circumferential surrounding portion reaching a topmost point is a first side portion, and a side opposite to the first side portion is a second side portion. The bearing portion has at least two foldable portions forming a first portion close to the first side portion and a second portion far from the first side portion. The adjusting strap is tensioned by the seat assembly and the first side portion when in the sitting state. The second portion is moved to form a seat portion during rotation to the sitting state, and the first portion is supported by the adjusting strap to form a backrest portion.
