The line is not speed, and it is not price. It is handrails and deck length. A walking pad has no handrails, which is what lets it slide under a desk; a treadmill desk keeps the frame and gains a longer, more heavily built deck.
| Under-desk walking pad | Treadmill desk | |
|---|---|---|
| Handrails | None — that is the defining feature | Usually, or an integrated console frame |
| Deck length | 39" to 47" on the pads we rank | Typically longer |
| Typical top speed | 3.7 to 4.0 mph | Often 6 mph and above |
| Fits under an existing desk | Yes | Usually sold as a desk-and-deck unit |
| Storage | Folds or rolls away | A permanent installation |
| Price | Lower | Substantially higher |
Where the MERACH sits
For most people reading this, a pad is the right purchase. The treadmill-desk case is real but narrow, and it is mostly about height and running. Our pad ranking is here.
In detail
330 lb sustained on a 41.3in deck, and it lives under the desk permanently.
Good to know At 67.7 lb it is built to stay where you put it rather than go into a closet between sessions.

Good to know Rated to 220 lb — leaving headroom above your own weight is what keeps the motor and belt healthy over years of use.

How we picked
Each product here is chosen the way a well-informed buyer would choose it: read the maker's spec sheet, manual and warranty terms; record the figures that decide whether a desk fits a body and stays still at height; confirm replacement parts are actually sold; then score it against a published rubric. The UPLIFT V2 adds something extra — it is owner-tested long-term, the desk Mike bought and works at daily.
Scores are weighted editorial judgments from that documented research, shown as a criterion-by-criterion breakdown so you can see which strengths earned each ranking. Nobody pays for placement. The rubric and the weights are on the How We Pick page.
Questions
No. The pads we rank top out at 3.7 to 4.0 mph, and none is constructed for running impact. Treat the speed ceiling as a design statement rather than a limitation to work around.
It adds movement to hours that would otherwise be sedentary, which is worth having. Whether it counts as exercise for your goals is a question for a doctor or a trainer, not a desk site — we stay inside what the evidence says.
You need a desk that goes high enough once you are standing 5 to 6 inches higher, and ideally one without a center foot bar in the way. The desk roundup covers both.

Specs come from the maker's own spec pages and manuals; health claims from named medical institutions and published research; tax mechanics from IRS material. Where a figure isn't published, we say so rather than estimating it. Read the full method.
