I have a gym with a wooden floor and wanted to protect it from damage. Use these mats is very simple. The mats can be put together in any form, only to an inner corner (to the chimney around) I had to cut off a small piece, so that it fits.
The only drawback: the mats slipping heavily on floor, I would have liked a non-slip layer on the bottom. For that I had an extra anti-slip mats buy and place underneath
