Seating element, back-rest and corner-rest. Trio comprises just these three simple elements, which offer an almost endless range of combina-tions — in just a few moves.Remove the corner-rest and you have a cool recamier. Take away the corner-rest and the back-rest, and the result is a wonderfully spacious sofa-bed. Add a couple of stools and you have a comfortable reclining area, perfect for lolling around on a lazy Sunday. A laid-back seating ensemble for a cocktail party. Or an extra-long sofa, upon which even squabbling relatives can be kept a good distance apart.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. The welting is concealed internally, and this allows the removal of the seating elements.
