Tired of Bedsheets That Won’t Stay Put?

Do any of these sound familiar?

You wake up, and one side of the sheets has popped off

The sheet bunches up under your back while you sleep

You end up fixing the bed multiple times a week

You've tried different sheets, deeper pockets, tighter tucks, and nothing works

How to Install Zlumber®

Slide the Lock body under the mattress at each corner. No tools needed.

Pull your fitted sheet over the mattress, leaving a little slack at each corner.

Feel for the channel on top of the Lock body — that's where the strip locks in.

Press the strip firmly into the groove to secure the sheet in place.

Tuck any remaining fabric and repeat steps 2–4 on every corner.

Lift mattress if bed has side rails.

Not too tight, keep loose.

Slide the strips on each Sidelock

Ensure everything is locked in.
