It seems the world became obsessed with folding metal furniture. Or maybe it’s just me. Here is another beautiful example of this efficient eco concept – Recto Verso collection from Krizalid Studio. The line includes a coffee table and a bookshelf, both of which are constructed of 2 mm perforated sheet of steel. The items arrive to you flat, and you assemble them following the simple diagram. There is virtually no dounside to this design – the items are sturdy, minimalist looking, flexible (the shelf can be folded in two different ways, which allows for the tilt to the right or left), the material itself is recyclable. Recto Verso shelf received an honorable mention at the Reddot Design 2011. Both pieces are available for purchase at the SitOnDesign.
