you should be able to remove it but you dont need to, i think the couch will be back to normal when a new mod-patch comes. the object is still accessible:

so you should be able to take it or destroy it

"we" decided to just wait for a mod-patch bc now we have the biggest sofa in the world and our entrance fee is 100 element or 500.000 element dust ;) - the people come from far away bc it looks so inviting. come here - sit down - rest a bit
