This verion of Mata is ideal for class rooms and industrial areas - training rooms, dining, cafeterias and food halls. The Heavy Duty version adds an extra strong frame made from thicker 2mm steel tube. Rated to 140kg it is even more durable than the standard Mata Visitor. The flexible back and kick back legs make Mata very resilient to accidental tipping from even the most active sitter. The polypropylene shell will retain its flexibility and colour fastness for many years in indoor situations. Mata does not have UV stabilisers or rust proofing suitable for prolonged outdoor use.
