Choose the correct mattress size and sheet size
Use deep-pocket fitted sheets for thick mattresses
Place the sheet evenly over all four corners
Pull each corner fully under the mattress
Start with the top two corners, then the bottom two corners
Smooth the sheet tightly across the mattress surface
Use sheet straps or suspenders under the mattress
Add corner grippers or elastic sheet clips
Tuck the sheet more firmly under the mattress edges
Use a mattress topper only if the sheet is sized for it
Wash and dry sheets according to care instructions to preserve elasticity
Replace worn-out fitted sheets with stretched elastic
Rotate the mattress if one side causes more slipping
Place a non-slip mattress pad underneath the sheet
Avoid oversized sheets on smaller mattresses
