MYNORVELLAA™ Expandable Shelf Riser - Add another usable level wherever a shelf has room to spare.
An expandable steel riser that turns unused shelf height into another storage surface. Adjust the width from approximately 13 to 22 inches, place it where another level would help, and leave the cabinet itself unchanged.
Open a kitchen cabinet and look above the mugs.
There may be six inches of empty air.
Look above a stack of bowls.
More empty air.
The bathroom cabinet does the same thing.
So does the pantry.
So does the closet.
The shelf is not necessarily too small. It is simply giving everything one horizontal surface when the cabinet has height for two.
The MYNORVELLAA Expandable Shelf Riser adds that second level without changing the cabinet.
Set the width anywhere from approximately 13 to 22 inches.
Place taller items below where the clearance makes sense.
Use the raised surface for shorter items above.
If the shelf changes later, adjust the riser or move it somewhere else.
No holes.
No shelf pins.
No adhesive.
No permanent decision about where the extra level has to stay.
One simple piece can solve several different shelves.
The cabinet already has the height. This gives you a way to use it.

One shelf becomes two working surfaces.
One shelf becomes two working surfaces.
The riser creates a raised level approximately 6.5 inches high.
That lets you use the area above shorter items instead of stacking unrelated things directly on top of each other.
The benefit is simple: two accessible surfaces within the same shelf opening.
Adjust the width instead of searching for the perfect fixed size.
Cabinets are rarely standardized enough for one exact riser width to feel right everywhere.
The sliding overlap design allows the shelf to expand from approximately 13 to 22 inches.
Use less width in a compact cabinet.
Open it farther across a broad pantry or closet shelf.
The same piece can make sense in more than one location over time.
Nothing has to be added to the cabinet itself.
The steel riser sits directly on the existing shelf with silicone contact feet underneath.
There is no permanent installation.
That makes it particularly useful when the space needs to stay flexible.

Measure the space above as well as the shelf itself.
Check the shelf width and depth, then make sure there is enough total vertical room for both the items below and anything you plan to place on top.
| Adjustable Width | 13–22" |
|---|---|
| Depth | 9.5" |
| Height | 6.5" |
| Recommended Use | Kitchen, bathroom, pantry, closet and household shelving |
Measure the space above as well as the shelf itself.
The riser adjusts from approximately 13 to 22 inches wide, measures 9.5 inches deep and stands 6.5 inches high.
Check:
- Available shelf width
- Usable shelf depth
- Total vertical clearance
- The height of items you plan to store underneath
- The height of items you plan to place on top
A riser can create another level only when the cabinet has enough vertical room for both rows.
