Highstack and Lowstack, a cabinet and chair, respectively were designed by Bratislava-based ALLT, as complementary pieces, both derived from the concept of stacking unfinished wood planks between wooden spacers in order to facilitate air movement and drying. Unfinished wood is most malleable and best-suited to manufacturing processes when containing a relatively low moisture content. Freshly-sawed wood, often set out to dry either in open air or in artificially-heated kilns, can take weeks and months to dry out, as it contains high levels of water and sap. To facilitate this drying process, the roughly processed dimensional lumber that leaves a mill is stacked in layers, separated and elevated by thin, wooden shims. Air and heat pass through the resulting cavernous spaces, carrying away water through evaporative cooling. This industrial process has been applied to the formal expression of Highstack and Lowstack, and, when combined with a randomized technique regarding the size and texture of individual components, lends a dramatic aspect to these pieces of furniture. 

These works exemplify the variety of functions that can result from the multiplication and aggregation of constituent design elements. When a single module is used, the resulting Lowstack can be utilized as a chair. When two and three modules are literally stacked, a cabinet results.
