I admit that it could get annoying, hehe. But thank you for answering some of my questions, even the QM guidePeroK said:

SUMMARY
Quantum tunneling probability decreases exponentially with increasing mass, making tunneling of large objects like sofas effectively impossible. Particles bound within atoms or molecules do not behave as free particles; their tunneling probabilities are constrained by binding energies and potential barriers. Stable molecules have lower net energy than their separated components, preventing spontaneous decay via tunneling. Macroscopic objects experience rapid decoherence due to many degrees of freedom and environmental interactions, collapsing superpositions and localizing wave functions, which suppresses tunneling at large scales. Phenomena like alpha decay exemplify tunneling in nuclear physics, but macroscopic tunneling remains negligible due to these quantum and environmental constraints.
