Things to consider when purchasing an Alaskan King mattress?

Before you purchase a mattress of this size it is important to consider a few things.

FREQUENCY OF USE – How often will you be sleeping on this mattress? Will it be an every night sleeper or a fun lounge area for watching tv? This will change the type of mattress that will be required. An every night sleeper will need to be more like a standard mattress build up to support your body and pressure points while a lounge mattress could easily get away with being a standard piece of cheaper polyurethane foam, similar to a couch. 

THICKNESS – Does your mattress need to be a certain thickness to fit into the platform it will be sitting on? Many Alaskan bed platforms require a set thickness for the mattress. 

PRICE – How nice of a mattress do you want this to be? Price can vary by thousands of dollars for a mattress this big so you need to decide how important comfort is to you vs affordability.
