Nope. You're probably abusing flexbox. This layout:

| HEADER | |Nav|Content|Sidebar| | Footer |

is more what we're talking about. You could do that, but it's not what flexbox was meant for. Try grid out. It will work easier for grid like layouts.

I know what layout you're talking about and it's trivial with flexbox. Why would you need a grid for that?

You don't _need_ grid, but it does make it simpler. You technically don't need flexbox either.

In grid you can define this layout in a single construct. Whereas with flexbox, you're defining several nested flex elements to get there.

You can think about the entire layout as a unit, rather than the horizontal parts first (sidebar/main content) then the vertical (header/footer) or vise versa.
