an adjustable protective platform for supporting, for example, potted plants includes a plurality of multi-legged links. Each link includes a pair of linkage legs angled with respect to each other at an acute angle. Each linkage leg includes a plurality of projections extending from the upper and lower surfaces and at least two transverse slots cut into the upper surface, extending from the outer side to the inner side, and angled at least partially towards the origin end of the opposite linkage leg. The slots in each linkage leg are symmetrical with respect to the slots in the opposite linkage leg. Therefore, the links are coupled together by arranging the links in an alternating up and down (one link facing up and the next facing down) fashion forming an outer enclosed loop, and further, by engaging a slot in a linkage leg of an upward facing link with a slot in an immediately adjacent linkage leg of an adjacent downwardly facing link. When the outermost slots of the linkage legs are engaged with each other, the size of the protective platform is maximized. Likewise, when the innermost slots of the linkage legs are engaged with each other, the size (diameter) of the assembled platform is minimized.
