You may remember Konstantin Achkov's flat-packed plywood furniture from when we captured it as a standout at the 2012 Sofia Design Week. While he's obviously known for his breakdown-focused furniture, his Coroflot portfolio boasts a number of impressive—more recent—designs that don't skimp on complexity in lieu of its simplified flat-packed nature. Take the Electron Chair, for example. Achkov describes the shape as incorporating a "puzzle principle," and that's one description that doesn't get lost in translation with this work.

Electron is made out of beech plywood cut with a CNC router. There isn't a single screw or drop of glue used in the chair's construction—instead he chose to use pin joints—falling even more to its puzzle-like nature. This is the first time we're seeing a textile element in Achkov's work, with the bold fabric seat and back of the chair. Tip the seat on its side and you might notice a familiar shape: "The side-view of the symmetrical geometric form looks like electron symbol," Achkov says. The lace-up detail on the underside of the seat is a nice touch, too.

In addition to the Electron Chair, Achkov has also released the Series "Lese", which includes a lamp, chair and table/stool design. The trio continues the puzzle theme with jointed legs and bases that fold into each other when packed down. The only parts that are attached with a screw are the chair's legs and seat back. "In the Lese Series I combined standard tapered wood legs with simple puzzle shape," the designer says. "The transparent seat and back enhance structure of chair and stool."

According to the designer, the legs and base of the lamp incorporate magnets to keep the design upright and sturdy. And it wouldn't quite be an eye-catching design without a brightly colored contrast cord, am I right? Just picture the orange-seated Electron Chair nestled next to the similarly hued lamp cord. Details, people.

There's much more flat-pack fun where that came from. You can check out more work from Achkov on Coroflot.
