Plastic-coated steel wire, of the kind usually found in baskets sitting inside or alongside sinks, frames each shelving layer rather than an impermeable surface, though other variants exist as well (both covered and uncovered).
We are all familiar with drying mats, collapsible wood, plastic or metal dish racks and other solutions, but even hanging dish drainers exist on the shelves of stores like IKEA, but few let one bypass the interstitial step of drying then putting away dishes.
Unlike many non-appliance amenities, this (loosely translated) ‘dish drying closet’ design and many subsequent variations can be traced back to a single inventor: Maiju Gebhard, who created it as part of the Finnish Association for Work Efficiency in the mid-1940s. Since then, though, it remains an elusive fixture in many modern kitchens outside its home continent.
