A foldable seat device, comprising, in combination:

• a flexible seat;
• a first leg means providing diagonally extending support legs along both sides of the device, and rigidly interconnected by a rear transverse upper support bar, the support legs extending from a rearward upper end to a forward downward end providing a front support leg engagement of the ground;
• a second leg means providing diagonally extending supportive upper legs along both sides of the device, and rigidly interconnected by a forward transverse upper support bar, the supportive upper legs extending from a forward upper end to a lower end, there being pivot means, at each side of the device, pivotally connecting the lower end of each respective one of the said supportive upper legs to a generally central portion of the respective support leg of the first leg means;
• and the said second leg means also providing diagonally extending supportive lower legs, along both sides of the device, the said supportive lower legs at their lower ends providing rear support leg engagement of the ground;
• there being a supportive connection connecting the upper portion of the said supportive lower legs of the said second leg means to the respective support legs of the said first leg means, said supportive connection being at a location spaced from the said pivot means;
• the respective supportive upper legs and the supportive lower legs of the second leg means being non-co-linear, and with the second leg means at each side of the device receiving force from the supportive upper legs of the second leg means by transmission of such force through a portion of the first leg means which is between the said pivot means and the said supportive connection.
