    Number of People to Sleep on the Bed

    The first thing to consider when buying an Alaskan king mattress is the occupancy. It means checking the number of people expected to sleep on the bed.

    Size of the Room

    Room size is another important factor to consider that affects the fitment of the bed. This bed requires an extremely large room with a minimum square footage of 16 feet by 16 feet. Then only you can easily place dressers and nightstands in the room and can have some space to move around in the room.

    Extent of Firmness

    Firmness preference varies from one family to another. Though, it’s difficult to find the different range of firmness options.

    Availability of the Mattress

    Also, check if the mattress is easily available at retailers. Otherwise, you may have to get it customized, which takes time. You should keep in mind the time and price factor when ordering a custom-made mattress.

This is because these materials provide better comfort and temperature regulations.
