Roundhill FurnitureRoskilde Storage Wood Office Desk, Blue

How is the back? Does this have to be placed against a wall or would it look okay in if you could see around it?

What hardware is required for assembly (screwdriver/Allen key)? Is it included?

Is this a true blue or an aqua color?

Is the main desk top really only 29.5 inches high? after looking at a measuting tape that seems very low.
