Elevate Floorstanders to Ear Level?

My Totem Sttafs, when positioned directly on the floor, are below ear level for listening purposes. I've read that optimum results occur when the tweeter is level with the ear. Since these speakers are in my home office, and I generally sit in my desk chair, I'm wondering if there's any value to raising the speakers up one foot. That would bring the tweeter in line with ear level. Your comments and thoughts are appreciated.
