The perfect nap

I read somewhere a while ago that the perfect afternoon nap should be along the following lines;
First make yourself a cup of coffee
drink it (or course!)
Find a comfortable armchair and stool/seat to rest your feet on
Close curtains/put on some background music*
fall asleep until the caffeine hits your system (about 20 to 25 minutes)
and wakes you up.
works for me!

*Jazz or light classical i.e. eric satie.
