Last row Relax Seat

We offer seats that maximize space and allow you to relax even in the last row

From “Seat to sit that requires patience “ To “Seat you are willing to sit down"

conventional sheet

With conventional seats, when you try to recline the seatback too far, it hits the interior parts of the car, making it impossible to respond to customers' feelings of ``I wish the seatback could recline a little more.‘’ , which leads to the impression that the last row seat is a seat to sit with patience

Last row Relax Sheet

The seat back can be tilted down greatly with only one lever operation and the customer's weight transfer, so you can make the most of the limited space.
Also, by linking the ottoman, you can relax more.

We are developing and researching so that we can offer the comfort of the rear seat that can only be experienced in high-end grades in ordinary cars, SUVs, and mini-cars.
