Description
This 2-tier clamp-on desk shelf is an above and under desk corner organizer that clamps to the desk edge, adding two levels of storage without taking any desktop space. Desk space runs out at the corners, which is also where nothing useful fits. This Calmility shelf clamps to that corner and adds two tiers of storage in air you were not using, without taking a single square inch of the surface you actually work on or needing a single hole in the desk.
Mount it above the desk for monitors, speakers, plants and reference books, or clamp it underneath for a laptop, a console, cables and things you want out of sight. Because it fixes with a clamp rather than screws, you can move it along the edge, switch it between desks, or take it with you when you move without leaving any trace behind. Because both tiers sit above or below the working surface rather than on it, the desk itself stays clear for a keyboard, a notebook and a mug, which is all most people need in front of them.
It carries up to 10kg per shelf on a rectangular frame with strong screw fixing, in a plain black finish that disappears against most desks. Check your desk edge thickness before ordering and tighten the clamp against a flat section, not a rounded lip. Free US shipping on every order, with 30 day returns and refunds.

Desk Space Without The Desk
You do not need a bigger desk, you need the air above it. Two shelves go up over the surface you already have and the workspace doubles without taking another inch of floor.
Clamps On, Stays On
The clamp grips the desk edge and tightens by hand. No screws into the wood, no drilling, and it moves to a new desk whenever you do.
Two Levels Above The Keyboard
Headphones, a plant, notebooks and chargers move up to the shelves and the space in front of you stays clear for actual work.
Frequently Asked Questions
What thickness of desk will the clamp fit?
It opens wide enough for standard desktops, including thicker solid wood tops. The pads inside protect the finish while the clamp tightens down.
Will it mark my desk?
Soft pads sit between the clamp and the surface on both sides, so veneer, laminate and finished wood all come away unmarked.
How much can the shelves hold?
Books, headphones, a monitor riser load of small gear and a plant or two. The steel frame is rated well above what most desks ever carry.
Can I put it on either side?
Yes. It clamps anywhere along a free desk edge, so left, right or centre all work depending on how you sit.
How long does it take to fit?
A minute or two. Slide the clamp over the edge, turn the knob until it is firm, and start loading the shelves.
