There are two types of Queen-sized beds, the Standard Queen and the California Queen, and the two sizes differ from each other by about four inches in each direction. It is important to pay close attention to the differences between the two beds, especially when buying sheets and other linens.
Queen-size beds are a great choice for today's larger people.
The Standard Queen is used in softside waterbeds, innerspring, and foam beds. Standard size of the mattress is 60" X 80" but quite often manufacturers are a little off in their sizes. 76" X 80" is also a popular standard Queen size.
The California Queen is also the standard for Waterbed Queen since waterbeds were invented in California. This is 60" X 84" Why is California Queen much taller? With wood frame waterbeds it's important that it be taller so that 6 foot sleepers are not scrunched up.
When you buy linens be sure they are deep enough. Usually bargain brand sheets are made for a 6 inch mattress and this simply won't do on modern deep mattresses. Wood frame waterbeds are about 9 1/2" deep and many softsides are much deeper.
