and a collapsible frame for suspending an item above a heat source, the frame comprising a plurality of vertical sides, at least one of the vertical sides being designated as a first side having user-selectable variable construction and the sides other than the designated first side collectively constituting the remainder of the frame; wherein the first side having user-selectable variable construction is constructed of at least one panel selected by a user from among a plurality of panels available for constructing the first side and wherein the panel removably attaches to the remainder of the frame and wherein the remainder of the frame attaches to a user-selected combination of multiple ones of the available panels vertically stacked along the first side. ### Claim 2 (depends on 1) The device of claim 1 wherein the device operates in at least one user-selectable in-use configuration wherein the first side having user-selectable variable construction is constructed with fewer than all of the available panels that are able to be used on a single side concurrently and any unused panels from the plurality of available panels are entirely excluded from the construction of the first side having user-selectable variable construction. ### Claim 3 (depends on 1) The device of claim 1 wherein the at least one panel selected by the user directly supports the transverse member. ### Claim 4 (depends on 1) The device of claim 1 wherein the at least one panel selected by the user is attached to the remainder of the frame along at least two different edges of the panel when installed in the designated first side. ### Claim 5 (depends on 1) The device of claim 1 wherein the at least one panel selected by the user attaches to at least two different components of the remainder of the frame. ### Claim 6 (depends on 1) The device of claim 1 wherein a vertical position at which the at least one panel selected by the user is attached to the remainder of the frame is selectable by the user from among more than one possible such position of attachment. ### Claim 7 (depends on 6) The device of claim 6 wherein the position of attachment of the panel changes at least one of: a proportion of the first side that is substantially enclosed, which portion of the first side is substantially enclosed by the panel, or a height at which the transverse member, directly supported by at least one panel, is supported within the frame. ### Claim 8 (depends on 1) The device of claim 1 wherein the first side having user-selectable variable construction is constructed of a first quantity of panels to establish a first value of a variable attribute and alternatively constructed of a second quantity of panels to establish a second value of the variable attribute, the variable attribute being at least one of: a proportion of the first side that is substantially enclosed or a height at which a transverse member, directly supported by one of the panels, is supported within the frame. ### Claim 9 (depends on 1) The device of claim 1 wherein the first side having user-selectable variable construction is constructed to comprise a first panel and a second panel, the first and second panels having different heights, wherein, in attaching the first and second panels to the remainder of the frame, the first panel is placed above the second panel to support the transverse member at a first height and the first panel is placed below the second panel to support the transverse member at a second height different from the first height. ### Claim 10 (depends on 1) The device of claim 1 wherein the first side having user-selectable variable construction comprises first and second panels, both concurrently attached to the remainder of the frame, and the transverse member is user-selectable to either be directly supported by the first panel in accordance with a first user-selectable configuration or to be directly supported by the second panel in accordance with a second user-selectable configuration. ### Claim 11 (depends on 1) The device of claim 1 wherein the transverse member is a grill.
