When Ordering Box Spring Encasings:  King-sized beds have 2 Long Twin box springs under the mattress rather than a King-sized box spring.  CA King-sized beds have 2 California Long Twin box springs. With this in mind, please make sure to order 2 of the appropriate Twin Long sized encasings for your CA King box spring.
