No, if there is one at the window and two in the centre - it's the beds on a 340.
Have a look at the cathaypacific.com web site and on the right there is a link to During Your Flight - choose Our Fleet.

Be warned however, that when I booked in Jan 02 the plane was a 744, and until last Monday it was a 340 with the old seats. I onlt found out when I check in at Sydney that it had changed to the beds.
