Compass four-legged chairs come in six sizes to cover the range of needs in the school. The Compass-LuPo chair has a comfortable air-cushion seat shell made from double-walled polypropylene – an environmentally friendly material that is very robust and can cope with the hardest conditions in the school day. The Uno-M is a classic amongst school tables. It can be fitted with an extremely robust LIGNOdur safety top. Under the table top it has a grid bookshelf.
