I am planning to build a React app using Bootstrap-4 and reactstrap (for the React Bootstrap 4 components) but I would also like to incorporate Google's material design into my app which reactstrap does not provide. My question is: could I use Material-UI with Bootstrap 4 instead of reactstrap? This way I would get the React components and also the material design.

Update (26/05/2017): Material-UI will soon be releasing their own grid system built with Flexbox.
