Buying guide · Updated October 2026
Which standing desk accessories are actually worth buying?
Most accessory lists are a list of things you can buy. This is a list of problems, in the order they will bother you — and the accessories that actually solve each one, including the ones that will not fit your desk.

What should you buy first for a standing desk?
A monitor arm, then a keyboard tray if your desk is too high for you, then input devices, then cable management. That order is not about price — it is about which problems you will actually notice. A monitor at the wrong height bothers you every hour. A cable crossing the work surface bothers you once a day.
The test we applied to everything below: does it change the ergonomics, or does it just add something to the desk? Only two accessories here pass that test properly.
The two that fix real problems
A monitor arm and an under-desk keyboard tray. These change how your body meets the desk. Everything else on this page makes an existing setup more pleasant without correcting it.
Ergotron LX Monitor Arm — buy this first
Puts the screen at eye level and gives back most of your desk depth.
The reason this one and not a cheaper gas-spring arm is the mechanism. It uses constant force rather than a gas spring, which means there is no pressure to lose over time — hence a lifetime warranty and a 10,000-cycle test rating. Most arms in this price band use gas and none of them warrant it for a decade.
It is built for sit-stand desks specifically: the arm adjusts between 5" and 22" in height, and the clamp fits edges from 0.4" to 2.4". That range covers most standing-desk tops, which is not true of every arm.
The limits matter. It is a single arm — a dual-monitor setup needs the extension and collar kit, sold separately. Grommet mounting needs a hole drilled in the desktop, so renters should use the clamp. And it caps out at 34" and 25lb, which rules out the largest displays.
Buy it if you have one monitor and a desk that moves. Skip it if you run two screens and do not want to buy the extension, or your display exceeds 34" or 25lb.
Clamp mount works without drilling; the grommet option does not.
BONTEC Under-Desk Keyboard Tray — buy this if your desk is too high
The cheapest real fix for a desk you cannot lower far enough.
If your desk bottoms out above your seated elbow height, this is the fix that costs least. It drops the keyboard to where your arms actually want to be and recovers roughly ten inches of usable desk depth at the same time. The C-clamp mount needs no drilling and will not mark the desktop, and the whole thing slides under the desk when you are standing, so nothing is permanently lost.
Three things will disqualify it. It needs 31.3" of clear width underneath, which narrower desks do not have. It will not clear a curved or bevelled front edge, or a desk with a crossbar — worth checking before ordering, because that rules out a lot of standing desks. And it is not sized for split ergonomic keyboards.
Buy it if your desk is too tall for you seated and you have the clearance. Skip it if your desk has a crossbar or a curved edge.
Rated to 35lb on a ball-bearing slide; 25.6"×11.8" platform.
Input devices: only if you have a reason
Do not replace a mouse you are happy with. Both of these solve a specific problem — scrolling volume, or wrist pain. If neither describes you, the money is better spent on the two items above.
Logitech MX Master 3S — best if you scroll more than you click
The MagSpeed wheel and three-device switching, plus genuinely quiet clicks.
The MagSpeed wheel is the reason it exists: a single flick carries you through a long document, and it switches between ratcheted and free-spinning depending on how fast you move. Switching between three devices with one button works across six operating systems, which makes it the obvious pick if you share a desk between a work laptop and a personal machine.
The clicks are around 90% quieter than a standard mouse, which sounds like a small thing until you are on a call in a shared room.
Against it: only a one-year hardware warranty, which is short for the money. It is not competitive with a trackpad if your work is gesture-driven. And the palm gets warm over long sessions.
Buy it if you type and scroll all day, or share a desk between machines. Skip it if you do everything with gestures.
8K DPI, three-device pairing, one-year warranty.
Logitech Lift Vertical Mouse — best for wrist pain
A targeted fix for forearm rotation, and cheap enough to try.
The 57° angle takes the rotation out of your forearm, which is what aggravates a lot of desk-related wrist pain — your hand rests in a handshake position instead of flat. It is designed for hands under 19cm, so small and medium hands fit properly rather than perching on a mouse shaped for someone larger.
Be realistic about two things. It takes about a week to stop feeling odd, and precision suffers during that week — do not try it the day before a deadline. It is right-hand only; the left-hand version is a separate listing. And the laser sensor will not track on glass, so you need a mat.
Buy it if a flat mouse or trackpad is aggravating your wrist. Skip it if you are left-handed or your wrist is fine.
Right-hand only — check you are buying the correct version.
The cheap ones that still help
Both of these cost less than a takeaway and solve a problem you will notice daily. Neither is glamorous and neither belongs on a wishlist, but a desk with cables sliding off it is a desk you will not enjoy using.
Anker 555 USB-C Hub — best for a one-cable desk
HDMI, Ethernet, card slots and three USB-A from a single connection.
If you dock a laptop, this is the difference between one cable and four. It carries HDMI at 4K60, gigabit Ethernet, SD and microSD, and three USB-A ports, with 100W pass-through charging so only one brick stays on the desk. It has more owner ratings than anything else in its price band, which means failures surface early.
Two honest limitations. It runs hot under full port load — owners report unplugging it between days — and pass-through is 100W in but roughly 85W out, because the remainder becomes that heat. It also outputs to a single display only.
Buy it if you dock a laptop and want one cable. Skip it if you need two external displays.
18-month warranty; single display output only.
Anker Magnetic Cable Holder — cheapest fix for cable mess
Sticks to almost any surface with no drilling, and can be moved again.
It sticks to wood, marble, metal and glass with no drilling at all, which makes it the rare cable product that suits renters. The adhesive can be washed and reapplied up to ten times, so a wrong first placement is not permanent. Six magnetic clips hold anything under 3.5mm — USB-C, Lightning, MagSafe.
Know what it will not do. It handles three or four cables, not a whole desk. It is not a substitute for routing power bricks — those need a tray. And it will not stick reliably to textured or vinyl surfaces.
Buy it if your first problem is cables crossing the work surface. Skip it if you need to hide power bricks.
Two-pack with five clips; check your surface is smooth and non-textured.
One thing accessory lists never mention
A desk that moves needs slack. Whatever you buy, leave enough cable length for the desk to travel its full range without pulling anything taut — and check it at full standing height, not seated, because that is where it binds. This is the most common reason a standing-desk setup fails after a few weeks, and no accessory on this page fixes it.
We scored all six on the same dimensions our quiz uses, from published specs and the limits each listing states. We have not hands-on tested these, and the fit caveats above come from the listings, not from our own assembly. Full detail is on our methodology page.
Frequently asked questions
What is the first accessory I should buy for a standing desk?
A monitor arm. It is the only accessory here that fixes two problems at once: it puts the screen at eye level, which is where it should be whether you are sitting or standing, and it frees up roughly half the depth of the desktop. Nothing else on this list changes the ergonomics of the desk itself.
Do I need a monitor arm on a standing desk?
You do if you use the standing position regularly. A monitor on its own stand is set for one height, so it is wrong for at least one of your two positions. An arm lets the screen move with the desk, and it returns desk depth that a monitor base otherwise occupies permanently.
Is a vertical mouse worth buying?
Only if you have wrist or forearm discomfort. A vertical mouse takes the rotation out of the forearm, which is what aggravates a lot of desk-related wrist pain, but it will feel wrong for about a week and it is right-hand specific. If your wrist is fine, a conventional mouse is the better buy.
Is an under-desk keyboard tray worth it?
It is the cheapest way to fix a desk that is too high for you, and it returns roughly ten inches of usable depth. But it needs about 31.3 inches of clear width underneath, it will not clamp to a curved or bevelled edge or to a desk with a crossbar, and it is not sized for split ergonomic keyboards.
How do you manage cables on a standing desk?
In two stages. First get the cables off the work surface with adhesive magnetic clips, which need no drilling and suit renters. Then deal with the slack, because a desk that moves needs enough length to travel its full range without pulling anything taut — that part needs a tray or sleeve, not clips.
