You can use this in any position(standing, seated, table/no table), but I feel before using this in any effect seriously consider your reasoning/justification for having the case out wether on the table or in your hands and make sure it makes sense as part of the routine. There will be certain effects that you will be much better off using standard deck switch methods involving pure slight of hand. Roberto Giobbi's book "The Art of Switching Decks" is probably the best out there. It covers everything you could imagine for deck switches. But cold case has its place and after purchasing I can say it is by far, currently the most practical and useful gimmicked switch on the market!
