The Kia EV9 7-seat version (2+3+2 layout) has a second-row bench seat, offering maximum practicality for families who regularly carry 5 or more people. The 6-seat version (2+2+2 layout) features two individual captain's chairs in the second row for a more luxurious and comfortable ride. There are further two 6-seat options: one with fixed captain's chairs, and one with swivel seats that can rotate 180 degrees to face the third-row passengers, a signature feature of the EV9.
Kia EV9 7 座版採用 2+3+2 佈局，中排係三座長椅，適合經常要坐 5 個人以上嘅家庭，實用性最高。6 座版係 2+2+2 佈局，中排係兩張獨立大班椅，乘坐感更豪華舒適。當中仲分為「大班椅」同「旋轉椅」兩種，後者嘅中排座椅可以向後 180 度旋轉，同第三排乘客面對面互動，係 EV9 嘅招牌功能。
