Easily wheel your luggage up the stairs.
Carrying a heavy stack of boxes or luggage is not a problem if you have a dolly. Until you meet its mortal enemy, the stairs! Stairs make it so that you need to carry the dolly itself every step, since the wheels won’t work. The Tyke Supply Stair Climber Tri-wheel Dolly overcomes this obstacle by using a patented tri-wheel design that can roll across stairsteps, making the whole dolly useful even when you have to lug it on top of the stairs.
