I have a DellaRobia sofa in my large room that has not been used under COVID conditions; Note that it sits on a smooth, high quality laminate floor. We have a puppy and a 9 year old dog who had "pied matches" in the outer corner of said sofa. No one has sat on this couch since I installed these replacement plugs, and the only movement has been to push the couch (which isn't a heavy couch) to the side to wipe up puppy pee about a half-dozen times. I've already had to replace 2 of the 4 plastic plugs in the last 4 months - and not the ones on the legs which dogs like so it's not like dog pee is failing them or anything. Keep shopping or buy a few extra bags.
