Under-desk treadmill review: is it worth it for home office in Switzerland?

Under-desk treadmills promise a healthier workday without leaving your home office. We tested the Urevo Spacewalk 3S and examined whether walking while working actually delivers on its promise for Swiss WFH routines.

Switzerland has one of the highest rates of home office adoption in Europe. Zurich, Geneva, Basel , across Swiss cities, the morning commute has been replaced by a short walk from bedroom to desk. That shift brought unexpected consequences: more sitting, less movement, and a growing awareness that stationary work is quietly damaging. Under-desk treadmills emerged as one response. We tested the Urevo Spacewalk 3S over six weeks of genuine WFH use to find out whether they deliver on their promise.

What an under-desk treadmill actually is

An under-desk treadmill is a walking-speed belt unit that sits flat beneath a standing desk. Unlike traditional treadmills, there are no handrails, no incline adjustments for running, and no large motor. The entire design premise is a slow, sustained walking pace , typically 1 to 4 km/h , while your upper body remains still enough to type, read, or attend video calls.

The Urevo Spacewalk 3S is one of the more popular models available in Switzerland through Galaxus and Amazon.ch, priced around CHF 380 to 420. It measures 140 cm long and 51 cm wide, runs on a 2.5 HP motor, and connects to a companion app for tracking steps and distance. Noise level is its main selling point: the manufacturer claims under 45 decibels at walking speed.

One member of the SwissMastery team has used the Spacewalk 3S as their primary desk setup for six weeks in a Zurich apartment. The floor is parquet, the desk is a Flexispot E7, and the work involves writing, video calls, and spreadsheet work , a realistic Swiss knowledge-worker profile.

The productivity question

The question every potential buyer asks: can you actually work while walking?

The honest answer is yes, with conditions. The first three to four days are genuinely awkward. Typing slows, concentration splits between movement and task, and video calls require conscious effort to stay still enough that the motion isn't visible to colleagues. One early call from the treadmill produced a comment from a Geneva-based colleague: "Are you on a boat?"

By week two, the adaptation is largely complete. Walking pace settles into background awareness, and focused work , writing, reading, analysing , returns to normal quality. Tasks that require manual precision (detailed spreadsheet editing, design work with a mouse) remain slightly affected. Tasks that benefit from mild physical activation , creative writing, reviewing documents, listening to podcasts , actually improve.

"Movement and cognitive function have a well-documented relationship. Low-intensity walking increases blood flow to the prefrontal cortex in ways that stationary sitting simply doesn't replicate. The key is that the movement must be slow enough to not compete for attentional resources."

Andrea Stocker, home office user, Basel

The productivity impact, after adaptation, is genuinely positive. Daily step counts on treadmill workdays averaged 8,400 versus 2,100 on stationary days , a meaningful difference without any additional time investment.

Noise and apartment living

For Swiss apartment dwellers, noise is the critical variable. Swiss building standards and neighbourly expectations mean that equipment noise is not an abstract concern.

The Urevo Spacewalk 3S at 2 km/h produces approximately 47 decibels in real-world conditions , slightly above the marketed spec, but comparable to a quiet conversation. At 3.5 km/h, it rises to around 52 decibels. On parquet flooring without a mat, the belt-on-floor vibration adds a low-frequency hum that travels through the building structure more than the sound itself suggests.

The solution is a dense rubber mat beneath the unit. Adding a 6mm rubber gym mat (available at Migros Sport or Decathlon) reduces the perceived noise from the floor below by roughly half. This is an essential accessory for anyone in a multi-floor apartment building and should be factored into the purchase budget.

A limitation worth stating clearly: if you live above others who work from home, the vibration during extended treadmill sessions (two or more hours) will likely cause friction. In a detached house or ground-floor apartment, this is a non-issue.

Space requirements in Swiss apartments

Swiss apartments are not known for surplus space. The Spacewalk 3S requires a standing desk , a seated desk puts the working surface too low for comfortable use while walking. A standard Swiss standing desk (Flexispot, Linak, or similar) occupies roughly 120 by 60 cm of floor space. The treadmill extends the footprint to approximately 200 by 65 cm.

In a typical Swiss studio or one-bedroom apartment, this means the treadmill becomes the dominant feature of the room when in use. It folds flat (the front section folds down to reduce the footprint by about 40%) but does not disappear. Storage under a bed works if the clearance is sufficient. Most buyers end up leaving it partly deployed against a wall.

This is not a disqualifying limitation, but it is a real one. Anyone with a dedicated home office room , common in larger Swiss apartments and houses , will find the space question trivial. For Zurich city apartments under 60 square metres, the calculus is tighter.

Who should buy one

The SwissMastery verdict: this is a genuinely useful tool for a specific type of worker. You are a good candidate if you have a standing desk already or plan to buy one, you work in relative isolation (solo home office, not a shared apartment during the day), your work is cognitively moderate (reading, writing, calls) rather than precision-demanding, and you are willing to commit to the two-week adaptation period.

The Urevo Spacewalk 3S specifically is a solid choice at its price point. Build quality is adequate without being impressive , the belt surface is firm, the controls are simple, and the app works reliably on both iOS and Android. For a sustained look at how the Swiss approach daily health discipline across all areas of life, the Swiss approach to quality over quantity is worth reading.

You should skip it if you live in a ground-floor Swiss apartment with downstairs neighbours, if you lack a standing desk and are not planning to buy one, or if your work involves detailed manual input for more than two hours at a stretch.

Alternatives worth considering

Two alternatives appear regularly in Swiss retail. The WalkingPad R2 (CHF 450 to 520) is slightly wider and quieter, with a more polished app experience but a larger footprint. The Mobvoi TreadMill Home (CHF 340) is the budget option , functional but noticeably louder and with a shorter belt that some tall users find restrictive.

For most Swiss buyers, the Urevo Spacewalk 3S sits in a reasonable middle ground: not the cheapest, not the quietest, but reliable and available with fast delivery through Swiss retailers.

The Swiss WFH health case

The broader context matters here. Switzerland's home office culture is established and unlikely to reverse. The average Swiss knowledge worker now spends three to four days per week working from home. The movement deficit that comes with that pattern compounds over months and years in ways that are well-documented.

An under-desk treadmill does not replace other forms of exercise. A regular runner or cyclist who already hits 8,000 steps daily will see less marginal benefit. But for the sedentary knowledge worker who genuinely struggles to move during work hours, the Spacewalk 3S offers a low-friction way to add several kilometres of daily walking without rearranging the day. That is a meaningful health proposition, not a gadget. The design philosophy , simple, purposeful, no unnecessary features , also aligns with the broader SwissMastery view of how to build a calm, intentional living environment.
