摘要： The disclosure relates to a sofa armrest. The sofa armrest includes a main body made by blow molding, the upper end of the inner side surface of the main body is recessed inward to form a fabric mounting groove for mounting armrest fabric, and the lower end of the inner side surface of the main body is provided with clamping-connection grooves for being connected with connectors of a sofa underframe. The sofa armrest is made by a blow molding process, and compared with traditional solid sofa armrests, the sofa armrest has the advantages of low weight, high production speed and less manufacturing materials; and the fabric mounting groove is used for mounting the armrest fabric, then the armrest fabric is prevented from protruding from the inner side surface of the sofa armrest, and the clamping-connection grooves are used for mounting the connectors of the sofa underframe, so that the sofa armrest and the sofa underframe are connected without gaps, when the armrest fabric is squeezed and deformed, debris accumulates on the lower wall of the fabric mounting groove or on a seat cover fabric, cleaning of dust and debris is facilitated, and the overall hygiene of a sofa is maintained.
