An ottoman is like a chair that you can put your feet on. It is usually a puffy cushion on top of a box that you can sit or rest your feet on. Ottomans are great because they help you be more comfortable when you sit on a regular chair or couch. Some ottomans can also be used as storage, so you can put toys, books, or blankets inside the box under the cushion. Think of it like a special seat for your feet and your things!
