A microwave cart is one of the lightest kitchen pieces to move once you separate the appliance from the furniture. Take the microwave off first and the cart itself is barely a two-minute carry.
Pro tip: If the cart has a towel bar or spice shelf, wrap it in a second layer so the thin bar does not bend under other items.
Watch out: Never move the cart with the microwave still sitting on top; the top-heavy weight can tip the cart on an uneven floor or ramp.
