Moving a Queen Size Bed

Alan and Jean are moving back to Hong Kong after college, and their bed will be temporarily stored at our place. Even though they live around 200 metres up the street, moving a queen size bed from a 4th floor apartment to my place across the road can still pose a challenge. Should we get removalists?

Not with my 1999 Nissan Pulsar though.

Thanks to Jason who came to help (and make sure the mattress does not fall out on the other side when I am cornering).
