The invention discloses an improved sofa which comprises an elastic cushion and a backrest connected to one side of the elastic cushion, wherein a gap is formed between a side wall of the elastic cushion and a side wall of the backrest; a dust absorption chamber, which can be compressed and restored along with the elastic cushion, is formed in one side of the elastic cushion; a dust absorption hole communicated with the interior of the dust absorption chamber is formed in one side wall of the elastic cushion; and a stopper, which can movably cover the dust absorption hole, is formed in the dust absorption chamber. When a user arises, the elastic cushion and the dust absorption chamber needs to suck air from the outside to restore to original shapes, the stopper is opened to act under the action of outside air, and meanwhile, fine sundries in the gap can be absorbed from the dust absorption hole along with air to enter the dust absorption chamber under the action of outside air; and when the user sits down, the elastic cushion and the dust absorption chamber are required to exhaust air to the outside due to the action of pressure, the stopper is closed to act under the action of air, and the fine sundries cannot be discharged from the dust absorption chamber under the obstruction of the stopper.
