Abstract: A floor structure for use on an ice surface includes sheets of rigid, lightweight material each having a topside and a bottom side which includes a margin and geometric recesses and recess dividers. Only the margins and recess dividers are in contact with the ice surface when this floor structure is laid upon the ice. The recess dividers effectively seal the geometric recesses creating sealed pockets which trap ambient air thus creating a thermal insulating effect which substantially prevents the coldness from the ice from penetrating the sheets to the topsides and prevents condensation from forming on the topsides making it safe for the users to move about upon this floor structure unlike other floor structures which are used on ice. In addition, this floor structure does not stick or freeze to the ice unlike the other floor structures, because it has a substantially smaller surface area which is in direct contact with the ice, making it much easier to remove and reuse.
