As a furniture installer, your duties and responsibilities are to deliver and assemble furniture to be installed in a residential or office building. You may work in the construction industry, completing furniture installation to specification, and you may mount cabinets, counters, or bookshelves before occupancy. Or, you may work in wholesale or retail outlets, where you show customers around the showroom and discuss options for their furnishing needs. You then deliver furniture to the customer’s home or office and install it.
