Welcome to the Q&A Forum

As others have said, that result is not, unfortunately, something you can outrank - it's not organic, and it doesn't have to compete with organic listings. Once Google determines the query requires a definition result, that one-box will be at the top. Why does Google determine this query needs a definition? Unfortunately, we're not entirely sure. It's possible you could do something to influence that decision, such as build a brand so powerful around the keyword that Google shifts the entire query to a different intent. Honestly, though, that's a tall order. So, what are some more realistic options? (1) Buy AdWords ads. Yeah, I know it's not the answer you expect from me, but the top 3 ads come above one-boxes (try a search for "assurance" to see what I mean). Sometimes, you do what you gotta do. (2) Work on mid-tail keywords surrounding that keyword. There are probably variants on "resting" that are more advantageous to rank for and will convert better. If your client isn't a household name, then people searching for "resting" probably aren't looking for them, and this isn't really that great of a keyword to obsess over. (3) Focus on "brand" signals like social accounts (especially Google+), get yourself into Freebase, and see if it's possible to get some kind of Knowledge Graph entity related to your brand. This is going to take some doing, but it's possible.
