Should you size up to king?
If you sleep solo
Save the king premium. A Casper queen gives one sleeper 60 inches of width, which is twice what most singles use.
If you sleep with a partner and no kids or pets in bed
The king gives each person 38 inches (the width of a twin). On a queen, you each get 30 inches. The Casper premium of about $308 is typically worth it if your bedroom fits a king.
If a child or dog joins you regularly
A queen leaves only 30 inches per adult once a third occupant is in bed. The king upgrade is usually worth it for the extra 16 inches of width.
