bed sizes

this shattered alot of what i thought i knew about bed sizes:

i thought a twin bed was an even 3'x6' and every level up added one foot to the width.

the way it actually works is:

• twin: 3'3" x 6'3"
• full: 4'6" x 6'3"
• queen: 5' x 6'8"
• king: 6'6" x 6'8"
• california king: 6' x 7'  (<-- my choice :-D )
