Abstract: 
In 2016, Garner and Schäppi gave a criterion for existence of finite biproducts in a specific class of monoidal categories. We provide an elementary proof of (a slight generalization of) their result. Also, we explain how to prove, by using the same technique, an analogous result including infinite biproducts.
