Safety in First Class Suites?

So I have been toying with the idea of flying first class ever since seeing the introduction of private suites as on the new Emirates or Singapore Airlines A-380s. It's not that I am scared or concerned but everyone keeps talking about airplane safety and then I ask myself how safe are these new types of cabin layout?!

Especially on Singapore Airlines where you have a separate bed folded over your actual chair, which is reclined in the process. What in an emergency? Every passenger has to fold back their bed, open up the chair, sit down, buckle up, all after being drawn from a possibly deep sleep?! Not to mention how the dividing walls and sliding doors could obstruct the escape routes after a rough landing.

I just find it a bit odd considering you're sometimes not even allowed to have your jacket in your lap upon take-off or landing, seeing as in the case of suites you'd have your entire bed-ware in the way. Anyone know what safety regulations say in this regard if there even are any?!
