What is the method for extending the rear seats of a BMW X1?

[JulietteMarie]

Reach under the seat cushion and forcefully lift the front part upward until the front buckle is released. This action needs to be performed once on both the left and right front sections. After lifting the front part, insert your left hand under the side, push the seat cushion toward the backrest with your right hand, and lift the rear part with your left hand to remove the seat cushion. Once the seat cushion is removed, you will see four fixing points on the floor. The front two are recessed and hidden, while the rear two are protruding hook structures. Simply replace it with a larger seat cushion.
