Height of Outpost Chair?

Does anyone know how tall the chair the payload specialists will sit in at the center of the field? I understand that there is a 4 foot wall, so I wouldn’t think any higher than a foot.

The chair is a few inches high, not much at all. It basically sits on the ground, its at a very nice angle leaned back/reclined as well.

It is essentially a stadium seat ziptied to a piece of plywood which rests on the ground.

Thanks for the info!
