How to Install Dofryna®

1. Insert on each corner

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

2. Stretch your sheets

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

3. Locate groove with fingers

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

4. Insert locking strip

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

5. Fold excess sheet and repeat on all corners

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

1. Slide under the mattress

Lift mattress if bed has side rails.

2. Lay your fitted sheet over

Not too tight, keep loose.

3. Slide the strips into each Sidelock

Slide the strips on each Sidelock

4. Tuck and finish

Ensure everything is locked in.

The Complete Sheet-Securing System

Say goodbye to loose, slipping, and bunching sheets—for good.

The Dofryna® Complete Bundle pairs Dofryna®Lock™ corner holders (4 pieces) with Dofryna®Sidelock™ (2 pieces) for true edge-to-edge coverage. Lock™ secures every corner; Sidelock™ targets the sides where sheets loosen most. Together, they keep your bed smooth, snug, and perfectly made—night after night.

Set up is effortless. Both products clip on fast with no complex fasteners, and their patented discreet design means they work invisibly beneath your bedding without compromising how your bed looks.

Built to last and gentle on sheets, this bundle is compatible with most bed setups—including adjustable and unconventional beds.

One bundle. Zero adjustments. The perfect bed, every time.
