Can anyone who has a Mamas and Papas Mamu pushchair tell me if a buggy board is compatable?

My concern is because the upright parts of the frame is oval shaped as opposed to circular like most pushchairs. I wondered if the buggy board adaptors would therefore not fit?

I have looked on the Lascal site but it doesnt feature the Mamu. It does show the Pliko which has similar shaped frame I think.

Thanks
