No-Slip Bed Sheet Lock

No-Slip Bed Sheet Corner Lock

A simple and effective solution for one of the most annoying bedroom problems: fitted sheets that won't stay in place.

This 3-part corner lock securely holds your fitted sheet in position without the need for elastic bands, straps, screws, clips, or additional hardware.

Simply place the corner frame onto the mattress corner, pull the fitted sheet over it, and insert the two locking sliders. The sheet is firmly clamped and stays securely in place throughout the night.

Important

⚠️ For the best results, use 4 corner locks per mattress (one on each mattress corner).

The uploaded files contain the parts for one mattress corner only.

For a complete bed setup, print 4 sets and install one on each corner. Using all four corners provides the best sheet retention and helps prevent the fitted sheet from shifting during sleep.
