Depending on how long and the item is on the flooring will determine really how long the indentations will last. If the items are only on the flooring for a short period, then the indentations should subside after some time. If the furniture is left on the flooring for several weeks or months, then you may still have some indentations even after the furniture has been moved. Our tiles are made from a different type of foam compared to to the typical rebond that is used as carpet padding. Rebond is made not to hold memory and typically what you see as an indentation is really the carpet fibers being pushed down. Over time with regular vacuuming and cleaning, the fibers and pad return to their original state. Our foam tiles, on the other hand, are not like that as they are made from more dense foam.
