Hi, this theme supports only right sidebar by default. But you can put sidebar to the left with some js codes.

paste this code to Theme Options / External JS box;

<script>
jQuery(document).ready(function($) {
    $('#primary').before($('#secondary'));
});
</script>

and use this custom css code to tweak it a bit;

#secondary .widget { padding: 0 2em 2.6em 0em; }
@media (min-width: 1200px) { 
	#secondary .widget { padding-right:4em; padding-left: 0; }
}
@media (min-width: 1400px) { 
	#secondary .widget { padding-right:5em; padding-left: 0; }
}
@media (min-width: 1600px) { 
	#secondary .widget { padding-right:6em; padding-left: 0; }
}
