Seating element, back-rest and corner-rest. Trio comprises just these three simple elements, which offer an almost endless range of combinations – in just a few moves. Everything fits together so well. Not by accident, of course, but by design. Trio’s basic building block is one metre long and one metre deep, and all the other elements conform to this. It is actually quite a simple building block system – but one which is incredibly soft and comfortable, thanks to the high-quality materials, elaborate workmanship and intelligent internal construction, which also includes a proper slatted frame.
