Cockpit seats 1, 2, and 4 were retrieved, along the bodies of PF and PNF. We do not know whether both bodies were retrieved simultaneous with the seat they were sitting in. My guess is that they were, for that would facilitate recovery. Retrieval of other bodies was deferred until after the DNA testing was completed on these two bodies.
This third interim report says very little about the bodies recovered in the last phase, where they were seated in the airplane, and whether the recovered bodies were all seated and belted. The report does say that the autopsy results for the bodies recovered by Ile de Sein were consistent with the autopsy results for the bodies recovered floating.

Rather strange that none of the pilots comments on the change in heading as the plane circles back.
