Is a Cal King Mattress Right For Me?

Consider a California king size mattress for…
Large master bedrooms:
The recommended room size for a king bed starts at 12x12, depending on how much additional furniture you have.
Taller body types:
Need a few extra inches? A California king gives you 4 more so you can stretch out.
Extra companions:
Invite a child or pet to snooze with you, without sacrificing too much space or comfort.
