Aaron’s last post reminded me of similar problems we encounter when customers try to get a mattress and foundation up a narrow flight of stairs.  King size mattresses do flex and they come with a split box instead of one.  This really helps a lot.  You can also get a split box in queen size — thus enabling the foundation to go upstairs.  WHEW!  Don’t worry that you’ll be stuck in twin beds!!! 

Oftentimes our customers ask, “What is the size of a queen size mattress vs. a king size mattress?” Here’s the scoop… Twin size is 3′3″ by 75″ long. Full size is 4′6″ by 75″ long. Queen size is 5′ by 80″ long and standard or Eastern king size is 6′6″ by 80″ long. California king, usually a special order, measures 6′ by 84″ long. I hope this helps when you are planning your bedrooms.
