No, ottomans are not all the same shape, and come in a variety of different options. Large round, square, and rectangle ottomans are often used as coffee tables, with decorative trays used as accent pieces on top. Long rectangle storage ottomans serve well at the foot of a bed and can store extra blankets and act as a soft spot to rest to put shoes on. There are even wedge ottomans that tuck nicely in unused corners or front and center as a dramatic piece.
