Moving and Logistics
Weight comparison
King mattresses typically weigh 10 to 20 lbs more than Cal King mattresses because of their extra width. A standard King memory foam mattress averages 90 to 130 lbs. A Cal King of the same type averages 80 to 120 lbs.
Fitting through doorways
The King's 76-inch width makes it harder to navigate through standard 30 to 36-inch doorways. The Cal King at 72 inches is slightly easier but still requires tilting and manoeuvring. Both benefit from mattress-in-a-box delivery.
Mattress-in-a-box options
Most online mattress brands (Casper, Purple, Nectar, Helix) ship both sizes compressed in a box. This eliminates the doorway problem entirely. The box for either size typically measures about 19 x 19 x 42 inches.
Will it fit in a pickup truck?
A standard 6.5-foot truck bed is 78 inches long. A Cal King at 84 inches will hang over the tailgate. A King at 80 inches will also hang over slightly. Both fit diagonally in a full-size truck bed with the tailgate down.
