Howwe tested them

WEch checked resist anc resistance to garage liquid liquidsu ids( petrol, oil,br brake fluid etc.) and hohow easy the mmats were to clean. They wwere then draggdragged across the floor to rate build qualquality and their abilityy to withstand scuscuffing.

A larlargearge bolt was plaplaced beneath each matm to assess ststurdiness and knee pprotection. We ccalculated the products’ducts’ area, volume and density (g/cm3),), all of which wawas balanced against comfort,c pr ac tic practicality and price.

They fell into two broad groups: smaller mats, suitable for minor tasks, and larger choices for lonlonger jobs.
