The China Eastern Business Class Kingbed seat measures an impressive 27 inches wide with armrests lowered, and more than six feet long in lie-flat mode. A shelf between the seat and window, or between seats in the middle row, provides plenty of extra arm and item space, as does an added shelf above the seat console. There is ample working space with both AC power and USB outlets. WiFi was sluggish when it was available. I opted to use the on-demand entertainment system instead and caught up on films on the 16-inch touch screen.
