Some chairs are more suitable for some purposes than others. A Shell Chair, for example, is great as an accent chair in one spot of the living room.  It looks great to stand it by itself. 
Something very alike happens with the Barcelona Chair but in X2!. The Barcelona Chair looks really great standing by itself, but the unique “X” frame of stainless steel, plus its tufted back and seat in black leather make it great in pairs. 
To produce the pairing effect, the ideal conditions are to dispose of two Barcelona Chairs, each one facing partially the other with a 45 degrees angle.  To do that, use your Barcelona Chairs, in front of a fireplace, at the end of a hall, or close to your backyard entrance. The effect is beautiful and magnetic. This is possible due to the sleeker design of the Barcelona Chair, of clean-cut lines and sober Italian Premium leather. 
If you want to feel the pairing effect of the Barcelona Chair, Barcelona Design is your best alternative in Mid Century Modern style furniture, with great classics like the Barcelona Chair, the Barcelona Sofa and more.
