A support ring for holding a fabric seat on an inclined frame tube of a portable chair frame allows the support ring to rest horizontally on the inclined frame tube so as to enable the fabric seat also resting horizontally on the chair frame. The support ring has a supporting hole contributed by two semi-circular portions and an intermediate portion extended between the two semi-circular portions. Each of the semi-circular portions has a diameter equal to or slightly larger than a diameter of the inclined frame tube. The intermediate portion also has a width equal to the diameter of the semi- circular portion. When the inclined frame tube fittingly passes through the supporting hole and is supported inclinedly with the horizontal, the support ring can be horizontally mounted on the inclined frame tube while a lower half of the frame tube resting on an upper edge of one of the semi-circular portion of the supporting hole and an upper half of the frame tube supporting by a lower edge of the another semi-circular portion of the supporting hole. Therefore, the fabric seat can be mounted horizontally on the chair frame and the downwardly force applied on the fabric seat can be evenly distributed and supported around the support ring.
