As mentioned above, according to the present invention, when the seat is normally used as a two-tiered seat, and when it is used as a two-tiered bed,
The lower ends of both seat bags of the opposing seat devices are rotated upward and connected to the opposing seat bags to form an upper bed, while the seat cushions and sub-seat cushions of the opposing seat devices are each rotated forward. Since the lower bed is created by moving the bed to the opposing seat cushion and connecting it to the opposing seat cushion, it is easy to convert from a seat facing the seat to a bed, or from a bed to a seat facing the seat. Since there are no hanging boards or angles above to support the upper bed, overhead space is increased and comfort is improved.

Also, when setting the lower bed, fill the gap between both seat cushions of the opposing seat by moving the seat cushions forward, and fill the gap at the rear with the sub-seat cushion provided at the rear end of the seat cushion. Since the lower bed can be filled with a seat cushion, it not only has the effect of making the lower bed wider, but also allows the seat cushion to be moved forward after the seat bag is rotated upward once, and the sub seat cushion can be moved forward. After pulling out Shion,
By lowering the seat bag again, a long seat cushion is obtained, which not only allows the user to stretch out their legs and rest, but also allows the user to set only the lower bed by operating the opposite seat in the same way.

In addition, the upper bed is formed by the seat back,
If you leave the seat cushion as is and use the sub-seat cushion as a seat bag, you can use the upper row as a bed and the lower row as a regular seat. It is something that you have.
