I've only ever had the seat facing me (I tried to change it around once and couldn't work it out ) which means that it never 'clicks' closed, you just collapse it and then have to try not to let it pop back up while you're hauling it into the boot of the car.
I usually unclip the handlebar adjusters (so that the bar can slide right down)
put my foot on the white break bit at the back of the chassis (ie the bit nearest you when you're pushing)
press button & pull the white slidey things upwards
the buggy then starts to collapse (at which point I remember that it's much easier to do if there's nothing in the shopping basket & have to retrieve that)
I squeeze the bit on the back of the seat headrest & fold it all the way down to meet the seat
and then it seems to have collapsed
it definitely gets easier with practise - and it's well worth it - the Bee is a great buggy
