The problem is that the Olympic Queen Size (which is 6" wider than a regular Queen and therefore a much more comfortable for two and not as huge as a King at 72"wide) has been discontinued over the last 3 or 4 years.
The mattress will be 60 inches (same width as queen bed mattress) by 72inches (8 inches shorter than queen bed mattress).
A split queen mattress is not as common as a split king sized mattress. A box spring for a queen bed can be purchased when the area for the bed is unreachable by the queen box spring in its original size.
A Regular Queen size bed measures 60" x 80" An Olympic Queen size bed measures 66" x 80" Depending on your headboard frame, you would have an overlap because of the extra six inches in width. If you put the mattress on a pedestal, with the headboard behind it, the look would be iffy.
queen

No. Two twin size mattress will fit a king size bed frame.
King Size mattress would be 76*80 inches and sometimes would vary according to the manufacturer. The length of the king size bed is the same as queen size bed, but king size bed is 16 inches wider than queen size bed. It is great to have a king size bed if you have kids or pets.
a queen mattress is 60" wide by 80" long. you have to take into consideration the size of bed if not using bed and only metal frame then that's the dimensions
Average queen mattress is between 90 & 110 lbs
