Singapore_Air,
I am so surprised that you do not know your beloved airline's product - shame on you for asking others about it. This is just outrageous for someone who eats, breathes and masterb**es over SQ 24 hours, 7 days a week.
For your info, SpacePrams have a system called the "Lumbar Support" which is common on all airline seats in the premium cabins.
Conclusion: Singapore_Air, there is no need to get excited about the message feature on SpacePrams - this is nothing special only that it is a lumbar support unit.
Any money, Singapore_Air has contacted SQ's Public Relations department demanding an explanation about this feature on SpacePram and telling them that he is totally unimpressed by the lack of details available to consumers. I bet he is very unpopular with SQ. I bet they hate his guts just like others on airliners.net (namely Anzett).
