  Compact symmetric spaces are probably one of the most prominent class of
formal spaces, i.e. of spaces where the rational homotopy type is a formal
consequence of the rational cohomology algebra. As a generalisation, it is even
known that their isotropy action is equivariantly formal.
  In this article we show that $(\mathbb{Z}_2\oplus \mathbb{Z}_2)$-symmetric
spaces are equivariantly formal and formal in the sense of Sullivan, in
particular. Moreover, we give a short alternative proof of equivariant
formality in the case of symmetric spaces with our new approach.
