The reason that this is called a 3-piece is that there is a sofa, chaise, and ottoman. The sofa and chaise actually lock together to make one piece and the dimensions are listed on the page. The ottoman is 35 in. x 24 in. x 19 in. This item will ship in three boxes and the dimensions of the largest box are 34 in x 15 in x 76 in and 100 lbs. Reversible means that you can assemble this unit with the chaise on the right or left side. Assembly is super quick and easy.
