California King size mattresses are 12" wider than a Queen bed but they add 4" in length. This may be a better choice for taller adults. This size is sometimes known as the "Western King", and bedding may be labeled either "California King" or "Western King". A California King bed set comes with one mattress and two half-width box springs to be more manageable when moving. The approximate California king width measurement per person is 36".

Pros: A California King size mattress is roomy in width for 2 adults. Also, it is the longest standard bed available at about 84", which is ample for most taller people.

Cons: This is a very large mattress that may not fit easily up stairs or into smaller rooms. Sheets are plentiful on the West Coast but may be a bit more difficult to find in other parts of the country, so try looking for them online if you're not on the West Coast. A California king size mattress needs 3 standard pillows or 2 king pillows for this width. All bedding is most expensive for California king mattress sizes. You can also buy this size mattress as a Split Cal King, which allows for the delivery of Cal King size mattresses to  facilities where doors do not allow  one piece sets.
