At what age did you stop using the changing table? - diaper changing table

My son is 7 months. old, 20.9 kilograms and 28.5 inches long. It is a great guy and he loves to fight, to stretch, look around, flip, and I can do anything to not change clothes or diapers. At what age did you stop with the changing table? What's next? Flat? Cot?
