Product Description
31.5" x 15.75" Work Surface. 27.95" to 43.70" Manual Pin-Lock Height. 88 lbs Capacity. 4 Wheels (2 Lockable). Treadmill and Walking Pad Compatible.
The JHK 31.5" Mobile Standing Desk is purpose-built for use with walking pads and under-desk treadmills. The compact 31.5" x 15.75" surface spans over a treadmill belt without obstructing movement, while the manual dual-action pin-lock adjusts height from 27.95" to 43.70" in seconds for seated-to-standing transitions. A thickened central steel beam and heavy-duty frame support up to 88 lbs with zero wobble during walking. Four wheels - two lockable casters and two swivel wheels - let you roll the desk wherever needed and lock it instantly by stepping on the lever. 27.95" wide wheelbase for stability on any floor. All tools included. Ships from United States. Available in Chocolate, White, and Black.
Note: Height adjustment is manual pin-lock (not electric). No keyboard shelf. No built-in storage.
Key Features
- Treadmill and walking pad exclusive design - The frame geometry and leg spread are specifically engineered to straddle a walking pad or under-desk treadmill belt; the desk sits over the treadmill rather than beside it, keeping your monitor and keyboard at ergonomic height while you walk; compatible with most standard walking pads and compact under-desk treadmills - verify your treadmill's width is narrower than 27.95" (the desk's wheelbase) to confirm fit
- Manual pin-lock height adjustment - 27.95" to 43.70" - 15.75" of vertical travel via dual-action pin-lock mechanism; pull the pin, slide the column to the desired height notch, release to lock - adjustment takes seconds; no electricity, no motor, no power cord; height is fixed at the selected notch position - not continuously variable between notches; suitable for users approximately 5'0" to 6'4" at standard sitting and standing heights
- 31.5" x 15.75" work surface - Fits a 14-15" laptop or a single monitor (up to 27") with a wireless keyboard in front; the narrow 15.75" depth keeps the center of gravity low while walking; not designed for dual monitor setups - the surface is optimized for focused single-screen walking pad work
- 88 lbs weight capacity - thickened steel beam - Central thickened steel beam resists lateral flex during walking; 88 lbs capacity comfortably supports a monitor (15-25 lbs), laptop (3-8 lbs), keyboard, and accessories with substantial margin; no wobble during normal walking speeds on a pad
- 4 wheels - 2 lockable casters + 2 swivel wheels - Roll freely on hard floors and most carpets; step on the lock lever to engage the two locking casters and fix the desk in place instantly; step to release and roll again; 27.95" wide wheelbase provides lateral stability when locked and during use
- Modern metal frame - compact footprint - Slim profile fits in small home offices, apartments, and shared spaces; fits over walking pads in corners and against walls; no large base footprint when not in use over a treadmill
- Quick assembly - all tools included - All hardware and tools included in the box; clear instruction guide; assembly typically completed in under 30 minutes
- 3 color finishes - Chocolate, White, Black - Chocolate: warm brown tone for natural or wood-accented spaces; White: clean bright finish for modern offices; Black: classic dark finish for contemporary or industrial setups

Frequently Asked Questions
Will this desk fit over my walking pad or treadmill?
The desk has a 27.95" wide wheelbase - the inside clearance between the legs is the critical measurement for treadmill compatibility. Most standard under-desk walking pads are 16"-22" wide (belt width), which fits within the desk's leg span. Before purchasing, measure the widest point of your walking pad including any side rails or handles at belt level and confirm it is narrower than the desk's inner leg clearance. The desk is designed for low-profile walking pads without tall side handles - tall console handles on traditional treadmills may conflict with the desk frame. The 31.5" surface width and low-profile leg design work with most Urevo, WalkingPad, LifePro, and similar walking pad brands.
How does the pin-lock height adjustment work and how many height positions are there?
The dual-action pin-lock uses a spring-loaded pin that engages holes in the vertical column at preset height intervals. To adjust: pull or squeeze the pin handle on both sides simultaneously (dual-action), slide the desktop column up or down to the desired hole position, and release - the pin snaps into the hole and locks the height. The adjustment takes 3-5 seconds. Height positions are fixed at the hole intervals - the desk does not lock at arbitrary heights between holes. The number of height notches is not specified in the product listing, but the 15.75" total travel range typically provides 6-10 positions at approximately 1.5"-2.5" intervals. If a very precise height is critical (for example, for a specific treadmill speed and ergonomic angle), note that fine-tuning between notches is not possible with this mechanism.
Can I use this desk without a treadmill as a regular standing desk?
Yes - the desk functions as a standard mobile standing desk on any hard floor or low-pile carpet without a treadmill. The four wheels with locking casters allow you to roll it to any location and lock it in place for use as a sit-stand or standing workstation. It works in home offices, bedrooms, living rooms, or shared spaces where you want a compact height-adjustable surface you can move easily. The 31.5" x 15.75" surface is on the compact side for a permanent primary desk but is well-suited for a secondary workstation, side desk, or occasional standing use. For a wider standing desk, the JHK 63x24" Electric Standing Desk with full electric adjustment is also available in this store.
Is the desk stable enough for typing while walking on a treadmill?
Yes - the thickened central steel beam and 27.95" wide wheelbase are specifically engineered to minimize desk sway during walking. At typical walking pad speeds (1.5-3.5 mph), the desk remains stable enough for comfortable typing and mouse use when locked. Stability is best on hard floors (hardwood, tile, vinyl); on thick carpet, the wheels may compress slightly and reduce rigidity - locking all four casters and ensuring the legs sit level helps. For maximum stability: lock all locking casters fully before starting the treadmill, place the heavier items (monitor) centered rather than at the edge, and walk at moderate speeds. The 88 lbs capacity means normal laptop + monitor + keyboard loads are well within the safe range.
What size monitor fits on the 31.5" x 15.75" surface?
A single monitor up to 27" fits comfortably on the 31.5" wide surface - a 27" monitor stand base is typically 8-10" wide, leaving room for a small wireless keyboard at the front. A 32" monitor is possible but its stand base may take up most of the width. A laptop (14"-16") plus a wireless keyboard fits well within the 15.75" depth. A monitor arm clamped to the back edge of the desk surface (if the desk frame allows clamping) frees up the full surface for keyboard and accessories and is the optimal setup for a monitor + walking pad configuration - it keeps the monitor at eye level and reduces surface load. The desk is not designed for dual monitors - the surface width and depth are optimized for single-screen focused use.
How do the locking wheels work and does the desk stay still when locked?
The desk has 4 wheels total: 2 swivel wheels (always free-rolling) and 2 lockable casters with a foot-operated lever. To lock: step down on the lever on each locking caster - the brake pad engages the wheel and prevents rolling. To unlock: step up on the lever to release. When both locking casters are engaged, the desk is fixed in position and does not roll during normal typing or walking use on hard floors. On carpet, locking effectiveness depends on pile height - low-pile carpet locks well; thick high-pile carpet may allow slight movement under significant lateral force. The two non-locking swivel wheels support weight but do not lock - the two locking casters provide sufficient stability for desk use when engaged.
