The $92.4million in furniture expenditures equates to spending about $6,000 for each one of the EPA's 15,475 disclosed employees, according to analysis from OpenTheBooks.com
The bulk of that spending, $48.4million, was on products from high-end retailer Herman Miller.
The 100-year-old-plus company 'places great importance on design, the environment, community service, and the health of our customers' and it had approximately $1.8billion in sales in 2013.
The EPA also spent $5million on modern furnishings from Knoll, the Washington Times
OpenTheBooks founder Adam Andrzejewski said: 'While private companies and citizens face more and more hardship from government regulation, the EPA literally sits in the easy chair.
'The EPA can't relate to the financial hardships regular Americans face.
'It's Herman Miller furniture for the bureaucrats, but Ikea for the taxpayers.'
The EPA defended its spending and said many of its offices had to move in the last ten years.
The agency said: 'New furniture purchases provided the agency the opportunity to obtain space efficiencies.'
The agency was previously criticized in 2003 for spending too much on furniture following a report by Public Employees for Environmental Responsibility.
Pete Sepp, president of the National Taxpayers Union, said: 'Apparently the long arm of the regulatory state needs a lot of comfortable chairs and desks to rest its collective elbow on, and EPA's 'elbow-print' is a big one.'
