a back panel linked to the seat panel along a first fold line; a support panel linked to the back panel along a second fold line; the support panel linked to one side of the back panel via a first web having a third fold line, and adapted to be linked to an opposing side of the back panel via a second web having a fourth fold line; a reinforcement panel having one end linked to the support panel along a fifth fold line and an opposite end, the reinforcement panel adapted to be positioned generally horizontally and under the seat panel in use; wherein each of the first and second webs has an extension linking the respective webs with at least part of the reinforcement panel. ### Claim 18 (depends on 17) A method of constructing a collapsible seat from a blank of claim 17, wherein: the first web includes a sixth fold line dividing the first web into two portions foldable towards each other; the second web is linked to a first joining means along a seventh fold line, the first joining means being adapted to be in registry with at least part of the back panel in use; the second web includes an eighth fold line dividing the second web into two portions foldable towards each other; and the reinforcement panel is linked to a second joining means along a ninth fold line, the second joining means being adapted to be in registry with the seat panel in use; and wherein the method comprises: (a) positioning the back panel generally vertically; (b) folding the seat panel away from the back panel until the seat panel is generally horizontal and on one side of the back panel; (c) folding the support panel towards the back panel until the support panel is superimposed on the other side of the back panel; (d) folding the first and second joining means towards the back panel; (e) connecting the first and second joining means to the back panel; and (f) pushing the first and second webs towards each other by applying pressure on the fold lines thereon; (g) folding the reinforcement panel towards an underside of the seat panel; (h) connecting the second joining means to the underside of the seat panel; and (i) pushing the extension of each of the first and second webs towards an interior of the seat by applying pressure on a respective fold line dividing the extension of each of the first and second webs into two halves foldable towards one another. ### Claim 19 (depends on 18) The method of claim 18, wherein: the second joining means or the reinforcement panel includes a tenth fold line, so positioned that the distance between the ninth and tenth fold lines corresponds to a thickness of the sheet material thereby enhancing the foldability of the seat panel when the second joining means is adhered thereon; and the reinforcement panel includes an eleventh fold line dividing the reinforcement panel into two portions foldable towards each other, the eleventh fold line being so positioned as to correspond to the sixth and the eighth fold lines; and wherein the method comprises: closing a gap between the reinforcement panel, and the first and second webs, by applying pressure on the eleventh fold line. ### Claim 20 (depends on 18) The method of claim 18, which includes the further steps of: collapsing the collapsible seat such that the back and support panels are on one side and abutting the seat panel; and folding the first portion towards the support panel resulting in a cavity defined by the first portion, the second portion and a third portion, bulging from an opposite side of the seat panel. ### Claim 21 (depends on 20) The method of claim 20 which includes a step of detachably mounting a sheet onto the collapsible seat, wherein each of the seat, back and support panels includes a cut-out, the cut-outs being adapted to correspond to one another when the seat is collapsed to form a carry handle, wherein when the collapsible seat is in a collapsed position with the back and support panels on one side and abutting the seat panel, the sheet having a tab and two tags adapted to engage the carry handle and the cavity of the collapsible seat respectively.
