 For simplicity we will now assume there is only one object and suppress it from the notation.

+A choice of homeomorphism $I\cup I \to I$ induces a chain map $m_2: A\otimes A\to A$.
 We now have two different homeomorphisms $I\cup I\cup I \to I$, but they are isotopic.
 Choose a specific 1-parameter family of homeomorphisms connecting them; this induces
 a degree 1 chain homotopy $m_3:A\ot A\ot A\to A$.
