For a queen set - if it states that 2 box springs need to be ordered - you are looking at the queen split this means one mattress ( 60" wide by 79.5" long ) and 2 foundations ( each 30" wide by 79.5" long ) placed side by side to complete the same dimensions of the mattress. Typically used for mall hallways / stairways.
Low profile refers to the height of the foundation / box spring. This is a personal preference has to how tall you want your bed ( also taking into consideration how high the actual furniture is )
Thank you for shopping at Sears. Have a great day!
