You mean the back cushions?

yes the back cushions, more specifically their height, and deepness of the bottom and top parts as they have this irregular shape.
EDIT: found measures: 100x32x7x23 cm
Seems you didn't notice it, but the measures are listed in the link I attached.
@mvc yes, I did not notice indeed, sorry and thank you for the help. Good to see that measurements match 😉
