Rollator

The walking frame that went to the gym and came back with wheels, brakes and a built-in seat. Push it along and it rolls smoothly, no lifting required, and when your legs need a breather, flip down the seat and take five. It's handy for anyone who needs a bit of balance and support to get around, whether recovering from surgery or simply tired of being told to "take it easy." Basically a shopping trolley with better manners and a handbrake.
