What door width do I need for a king mattress?

A king mattress (10–14" thick) on edge fits through any standard door (28"+ clear opening). The width of the mattress (76") doesn't matter because it goes through lengthwise. The limiting factor is thickness, not width.

Can I bend a mattress to fit through a door?

Innerspring and memory foam mattresses can bend gently around doorframes. Hybrid mattresses with coils are stiffer. Never fold a mattress in half — a gentle C-curve over 3–4 feet is safe for most types.
