Is the bedding, floor, or carpet considered impure if touched by feet or trousers contaminated with urine drops? And does the impurity transfer when they touch the bedding or anything else?

Sitting down to urinate is recommended, and it is advisable for a husband and a son to explain the Sunnah to them. One does not rule that feet and clothes are impure unless there is absolute certainty that impurity has touched them. With doubt, the original state of purity is presumed. If impurity is certain, the impure area must be washed, and prayer is not valid without doing so. If there is no certainty that impurity has transferred, the original state of what they touch is purity. When there is certainty of impurity and an impure area touches something wet, there is a difference of opinion and detailed discussion among scholars regarding the transfer of impurity. One must be wary of obsessive doubts (waswasah).
