This work presents a hybrid polyurethane nanocomposite coating reinforced with functionalized nano-SiO2 and graphene oxide for high-performance furniture applications. Surface modification via APTES silane coupling promoted uniform nanoparticle dispersion and robust interfacial bonding within the polymer matrix. Multiscale characterization using SEM, XRD, FTIR, and Raman spectroscopy confirmed successful hybrid nanostructure formation and strong matrix-filler interactions. The nanocomposite exhibited synergistic reinforcement: pencil hardness increased from HB to 3H, flexural modulus improved by 22%, and pull-off adhesion strength rose by 18%. Taber abrasion testing revealed approximately 40% enhanced wear resistance, while thermogravimetric analysis showed elevated thermal stability with the onset of degradation shifting from 284 to 308
