King size mattress
If two people are making the bed, one person can secure the corners at the foot of the bed while the other person secures the corners of the fitted sheet at the head of the bed.
King size beds require fitted sheets as well as flat sheets for a properly made bed. Putting fitted sheets onto a king size mattress follows the same concept as putting fitted sheets on any size bed. Though the king size bed is larger and requires more effort because of the sheer size, putting fitted sheets onto the mattress is an easy project that can be mastered and accomplished in a matter of minutes. For faster fitted sheet application, find a helper to tackle the bed making.
Spread the fitted sheet on top of the mattress, making sure that the sheet fabric is facing right side up. (Raised seams should be on the bottom side.) It will not spread out flat because of the elastic.

Locate the tag and/or care label on the sheet. Usually this is sewn into a corner seam. The end of the fitted sheet with the label goes at the foot of the mattress.
Grasp the elastic edge of the left bottom corner of the fitted sheet and stretch it over the left corner at the foot of the bed. Pull the elastic edge under the mattress corner to secure.
Grasp the elastic edge of the right bottom corner of the fitted sheet and stretch it over the right corner at the foot of the mattress. Pull the elastic edge under the mattress corner.
At the head of the bed/mattress, pull the sheet toward the head of the bed, straightening the fabric if possible. Grasp the elastic edge of the right top corner of the fitted sheet and pull it over the right corner of head of the mattress. Pull the elastic edge tight and under the mattress corner.
Grasp the remaining elastic edge of the top of the left fitted sheet corner. Pull the sheet taut and tug the elastic edge of the fitted sheet corner under the left corner at the head of the mattress/bed.
