Upholsterers add coverings and cushions to new and old furniture. Though some upholsterers specialize in creating new furniture or repairing old furniture, most work with both. Since many upholsterers do custom repair and design work for clients, it's important that they remain up to date with current trends and fabrics. Listening to the needs of a client and helping them choose the right fabric is an important part of this job. Balancing the client's style with the functionality they require can be tricky at times, and requires a knowledgeable upholsterer. For instance, some people want fashionable material that won't be harmed by their pets.
