Choosing speakers for room w/ obstructing sofas

I have only one place for speakers-- on either side of a fireplace bumpout, and there are couches perpendicular to speaker locations with 32 inch high arms. Should I buy floorstanders with drivers (mids and tweeters, at least) clustered toward top of cabinet, in order to clear obstructing sofa arms, or put monitors atop stands, keeping in mind that stands would have to be at least 30 inches high, probably more. I have purchased a new cd player and integrated amp based on Audiogon feedback, but cannot finish putting new system together as I'm stumped by this speaker issue. Help!
