A kitchen cart on casters is built to roll, which makes it one of the easiest pieces in the whole house to move, as long as you clear it first and keep control of it on ramps.
Pro tip: Bungee the lower shelf items in place temporarily rather than fully unpacking them if you are only moving the cart a short distance within the house.
Watch out: Do not roll a loaded cart over gravel, thick carpet edges, or door thresholds at speed; small caster wheels can catch and tip the whole cart.
