You’re current code does nothing with the clone. The item is being cloned but because it has no parent it doesn’t show up. I would also recommand putting the clone in a variable so you can easily acces the clone.
Try doing this and see if it shows up now:
local clonedObject = workspace.Items.Seating.Chair:Clone()
clonedObject.Parent = workspace
Objects must be parented to the workspace or they will not showup, they still exist but they aren’t visible. You must parents them to workspace (or a descendant of) workspace.
Upon cloning the object, it disappears. Lets say you have a part in workspace, you then say workspace.Part:Clone() if i’m correct, it should keep the part you’re cloning, then clone it, and default parent is nil. Whenever I’m cloning it, the object I am trying to clone gets parented to nil.
If the object you’re trying to clone gets set to nil that means there’s something else in your code what does that. :Clone() doesn’t do that. Maybe you’ve created a variable which targets the base object instaid of the cloned version?
