The average time it takes to reupholster a piece of furniture is around eight hours, but it varies significantly based on the piece. A professional can usually reupholster smaller furniture units like dining chairs or small ottomans in two to three hours, while an entire sofa might take several days or up to a week. Antique furniture tends to take longer to reupholster because greater care needs to be taken to preserve the piece. Your timeline might be a bit longer if you need other repairs done, like sanding and refinishing wood components.
