When the flatbed seats were first introduced on the 764s, there was some criticism on the design. If I remember correctly main focus was on the spring-loaded table as well as the narrowness in bed mode. I think there was even a thread saying that DL executives weren't happy with some of the details and wanted changes to be made before additional installments.

So far, I only had the flatbeds on one flight (ATL-LHR) and some of the criticism was certainly justified. Now that additional 764s are receiving lie-flat seats and 763s will soon follow, I'm wondering if any changes were made. Has anybody flown on the new versions?
