Chair Cover Problem... {SOLVED}

Hello everyone! Today I have a little problem.... I created the Eames Side Chair and I would like to add the cover (upholstery) on the top of the chair so I converted a random plant into the cover and using the cheat: bb.moveobjects on I can place the cover on the chair... Untill there no problems but unfortunately the sim can't sit on the chair because of the cover!! :( Is there anything I could do on Sims 4 Studio to make sure the cover doesn't bother the Sims? Or I will have to convert the cover from an ea chair but then It would be two chairs on the top of each other.... I share some screenshot for you guys. Thank you in advance for your help and suggestions!
