A foldable chair includes four supporting legs, each having a top portion, a bottom portion, and an intermediate portion, and four stretchers, each disposed to brace two adjacent supporting legs. When upper hook ends of the stretchers are slidably moved to a folded position to be proximate to the top portions, the two adjacent supporting legs are closer to each other. Four first coupling members are slidably mounted on the intermediate portions, and are connected to the upper hook ends. Four second coupling members are slidably mounted on the intermediate portions, and are disposed above and are engageable with the first coupling members. A flexible seat sheet is disposed to be grasped by gripping portions of the second coupling members and is tensed when the supporting legs are in the spread position. The length of the first coupling members of the front supporting legs is of a dimension such that, when the supporting legs are in the folded position, the top portions are disposed inwardly of the first coupling members. A pair of armrests are disposed at a desired position between the top portions of the two adjacent rear and front supporting legs for providing a satisfactory feeling of comfort when the chair is in use.
