NAICS 337910

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to support collection, analysis, and publication of U.S. economic statistics. Developed under the Office of Management and Budget with the Economic Classification Policy Committee in cooperation with Statistics Canada and Mexico’s national statistics agency, NAICS replaced the SIC in 1997 and is updated on a five-year cycle; the current vintage is 2022. ¹
NAICS 337910 covers establishments primarily engaged in manufacturing innerspring, box-spring, and noninnerspring mattresses, including mattresses for waterbeds. It is used by federal statistical programs (e.g., the Economic Census) to tabulate industry activity and by many acquisition stakeholders for market definition and reporting. ²
