A super king bed is a larger bed size that measures 72 by 78 inches (180 by 200 centimeters) in the US and 6'0" x 6'6” (180 x 200cm) in the UK
. It is considered an "oversized mattress" and requires a bedroom with dimensions of at least 12 by 12 feet to accommodate the mattress, bed frame, other furniture, and walking space
. Super king beds are custom-made and are often pricier than standard mattress sizes
. They are great for co-sleeping or couples who want more space to spread out
