The InMovement Difference

What sets the Unsit® Under Desk Treadmill apart?

Unlike compact walking pads designed for occasional use, the Unsit® Treadmill is built to move with you all day. Every detail — from its wider walking surface to its whisper-quiet motor and commercial-grade frame — is crafted to help you stay active, focused, and comfortable at work.

Extra-Wide Design – Ultra Quiet – High Weight Capacity – Built to Last

Extra-Wide Walking Surface

Move Around Freely and Comfortably
The Unsit® features a 30" × 40" walking surface — roughly 55% more usable space than standard under-desk treadmills. This short-but-wide design gives you room to move naturally while staying fully centered at your desk, eliminating the “tightrope” feeling common with narrow treadmills. The result: smoother strides, better posture, and greater comfort during long work sessions.

Ultra-Quiet Motor

Zero Disruption
At just 42.9 decibels, the Unsit® operates quieter than the sound of your footsteps. Its motor is precision-tuned for walking speeds, producing a low, steady hum that fades into the background. This makes it ideal for shared environments or remote work setups where focus and clear communication are key. You can stay active throughout your day — and your coworkers won’t even notice.

Higher-Than-Average Weight Capacity

Supports up to 400 lbs
Built with a reinforced steel frame and premium internal components, the Unsit® supports users up to 400 lbs — far exceeding the capacity of most consumer treadmills. This heavy-duty construction not only improves stability but also ensures the treadmill maintains its quiet, smooth performance under continuous use. It’s strength you can feel, backed by engineering you can trust.

Built to Last

Sturdy & Reliable, With a Lifetime Frame Warranty
Durability is central to the Unsit® design — and our warranty reflects that confidence. Every treadmill comes with a lifetime frame warranty, three years on the motor, and two years on parts, ensuring long-term performance and protection. When you invest in the Unsit®, you’re investing in equipment built to support your daily movement for years to come.

"Seriously, It's That Good"

"... I’m focused all day in meetings or coding, and I can average around 25K steps each day. This thing is a champ through it all. It’s quiet and always ready to keep going. It is also the talk of nearly every meeting with a new person and we chat for five minutes about how great this thing is."

Select Your Preferred Walking Speed

The control panel sits on top of your desk and allows you to adjust your speed up and down with a single dial. The Unsit® Treadmill runs between 0.3 - 2.0 mph, the optimal range for working while walking.

What Customers Are Saying

"One of the absolute BEST purchases I've made in a long time!"

"The financial investment kept me hesitant at first, but now that I have finally purchased the desk and have been using it for 3 months I am SO HAPPY !! It is worth every penny and then some. It's rare when you feel that a single purchase has really changed your life. I'm in the software and RE sales business and I have spent decades and LONG hours in front of a computer. Now, what a difference in my work day, my mood, & my physical well being!"

Unsit® vs. The Standard "Walking Pad"

While compact walking pads are popular for light, occasional use, the Unsit® Under Desk Treadmill is engineered as a commercial-grade active workstation. If you are looking for an office solution that survives an 8-hour workday, here is why the Unsit is a good fit for you:

1. Wider, More Stable Surface Area to do Your Best Work

  • The Problem: Most walking pads offer a narrow 16–18" belt, creating a "tightrope" walking effect.

  • The Unsit Solution: Our 30-inch wide walking surface supports a natural human stride, making it the most stable non-narrow walking pad alternative for focused work.

2. Quality Certifications & Safety Features

  • The Difference: While budget pads are consumer-grade, the Unsit is certified by TÜV SÜD, one of the most demanding safety certification programs in the world.

  • Safety First: This makes Unsit the primary choice for shared office treadmill solutions and corporate wellness programs where liability and durability are non-negotiable.

3. Built for Longevity, Not Just Convenience

  • Low and Infrequent Maintenance Required: Unlike cheap alternatives that require frequent belt alignment and lubrication, the Unsit is designed as a long-lasting under desk treadmill, with a lifetime frame warranty.

  • High-Weight Capacity: With a 400-lb capacity and reinforced steel frame, it is the only heavy-duty walking pad built for 24/7 reliability.

4. Quiet Motor for Low Disruption

  • Whisper-Quiet: While cheap walking pads often exceed 50+ dB or more, the Unsit stays whisper-quiet throughout the day to ensure it meets all your professional needs – from Zoom calls to heads-down work.

  • Zero Disruption: The Unsit is one of the quietest commercial treadmill desk available, ensuring you stay active on Zoom calls without background noise.

Buy nice or buy twice

This wide design and build quality that’s made for all day use is 100% mandatory
All other treadmills on Amazon will burn out on you within the first month and I learned me lesson.
This app is so cool that it adds steps to my iPhone health app and I’ve lost a few pounds already and can drink and eat more
I work from home and get to walk 7 hours and maybe sit for 1 ranging from 2mph to 1.5 1.2 1 and 0.8 mph
Your body will adjust but make sure to get the energy stool also and do plenty of breaks to stretch your foot claves and legs
I use a massage fun for my hip flexors and have been able to average 25k steps a day since I got this up from 3k

Walking like the Amish

My personal trainer said the Amish get 27k steps in a day on average. I was just cracking 10k before getting this treadmill and now I’m consistently over 20k steps per day. An absolute game changer! I was concerned how much typing I could do but honestly once I get in a rhythm it’s pretty easy to type even while walking at top speed. The speed ranges are really good and I don’t think I could go any faster and concentrate than the top speed. That said, I am one that finds walking very therapeutic and it helps me gain mental clarity. So not only are my steps way up but so is my productivity. My brain is literally firing on all cylinders. The build of the unit is top notch and the wider dimensions is a plus. Although I have a small office, it fits well. And when I’m not walking or standing I just put my chair right on the treadmill and turn the power button off. Worth the investment!

Built like a tank

I’m about 300lb, and was worried about ordering a normal treadmill for my desk setup due to most of them not supporting my weight. This thing is incredible, and the wider belt is perfect for me, making it so I don’t have to think about where I step.

Great treadmill and desk. Need more obvious instructions...

The quality of the treadmill and desk is top notch. Not like most consumer grade products. The only issue I had was, the should be some kind of bold printed paper added to the standing desk table in large red letters instructing the person assembling the table that the center rail component that holds the legs together must be EXPANDED to accommodate the width of the treadmill. If you don't expand the center rail, it looks like the treadmill will fit, but it doesn't, and you'll chip the paint on the legs like I did. Of course, is you read the fine print in the instructions, there is a vague reference to this. But, being the typical guy, who doesn't read instructions until I hit a snag. Just something simple... Like... "EXPAND CENTER RAIL SO WIDTH OF TABLE ACCOMMODATES TREADMILL". That might save some headaches. Worse yet, when I called the company to explain the problem, all the lady could tell me is essentially "well, it does fit" which caused me to a attempt putting the treadmill between the legs, only to scratch the paint. I was not told... "Hey, just find the somewhat hidden hex bolts used to expand the center rail". Aside from that, the app is supposed to work with the treadmill is worthless and does not work. So, without a pedometer, you have no way of knowing how far your have walked. And fyi ... pedometers contained in watched don't work if you're working on the desk because your hands are resting on the desk. Your need a clip on pedometer to go on your waist. Overall, I'm satisfied because it keeps me moving and eliminates back problems. I average 30000 steps every day now. Now, getting on my mountain bike at the end of the day to get my reps and time in is no longer compulsory since I've done enough for a moderate level is fitness.

I’m way less bored at work now. XD

I’ve been walking on my Unsit for about 4 weeks now, and I absolutely LOVE it.

After purchasing, I came across some other brands which were much much cheaper, and I immediately felt a sick sense of “holy cow, did I overpay for my treadmill?” But as I dug into the reviews of that brand, I read about some… let’s just say, less-than optimal experiences. That made me feel confident in my purchase, because mine has run so wonderfully from the day I set it up!

Set up was actually quite easy. I’m young and spry. I’m not *super* fit, but I have no trouble lifting heavy things and getting on my knees with my head to the floor (this position was necessary as I worked to align the belt properly; a perfectly normal step in the set-up). The box this thing comes in is AMAZING. You can flatten out the sides, and then there are wheels on the front of the tread and a handle at the back. Just flatten the box, lift up by the handle, and wheel it to where you want it to go. Brilliant!

It’s possible others who are not in my physical condition will need help setting it up, but I personally don’t think expert set up is needed for most. I was able to do it all by myself. It was really straightforward. Just set aside some time to play with it until it’s working the way you want it to. :)

The tread itself is so pleasant to work on. I have no issues working while walking at 2 mph (the fastest speed). It’s pretty quiet. I mean, obviously you can hear it, but it’s not distracting to me. I use it when on meetings sometimes, and it hasn’t been a problem. It’s obvious you’re walking (you’re bobbing, and the other person may hear faint footsteps), but no one has cared yet. :P I personally *prefer* to stay still during meetings (to avoid that added distraction) and walk while typing, which is opposite of what most people will say.

Walking while I work definitely helps a restless person like me feel much more excited to stay at my desk all day, and kinda gives me an excuse to actually work when I’m supposed to (since I’m here, ya know?)

My only con: the app leaves a little to be desired. I love that I can keep an eye on how far I’m walking each day, because this helps me avoid walking too much. I tend to injure myself by doing too much activity. Please be careful about this when you get started. I started immediately by walking 2 mph all day, going about 8 miles a day. This was a mistake. It’ll take your feet time to adjust to walking so much so regularly, even if you’re already an active person. Start slower and for shorter periods of time. My running coach recommended 30 mins a day, moving up a few minutes every couple of days. That’s painfully slow to me, but I’m not the expert. :P This will help your body adjust and avoid foot pain from overuse.

Back to the app—you have to be sure to re-connect the app each time you turn on the tread (not hard, just flip a switch. It’s just annoying I have to do it manually each time.) And you can’t really do anything useful with the data after the day is over. Yes, it shows you generally your stats over the week/month, but I can’t go back and see yesterday’s data specifically (which is kinda annoying for a data nerd like me). It will sync my steps to Apple Health, but it doesn’t sync them to Apple Activity. However, my overall calorie burn tracked by Apple Activity has been higher since I started using the tread. So I get the feeling that the watch is just tracking my elevated heart rate despite it’s lack of showing my steps, and I’ve decided that’s good enough for me.

All in all, this was a solid purchase that I’m extremely happy with. I’m giving it 5 stars despite the app thing, because the tread itself is top notch. :) I just hope the company has the resources to update the app to be more useful to data nerds.

P.S. If you want to sit down, I recommend getting a yoga ball. It’s safe to use on the tread and much less expensive than a special stool (though I’m confident Unsit’s stool is probably excellent). This is what I use at my sit-stand desk, and it’s perfect. It still encourages me to activate my core, so no matter whether I'm sitting, standing, or walking, I'm always encouraged to be healthier than slouching in a chair.

One of the best investments of my life

I am a software engineer who spent the pandemic slowly hurting my back sitting in front of my computer for 8-10 hours per day, until about six weeks ago when I got a sciatica problem. I couldn't stand the pain, so I decided to invest in this treadmill + desk bundle instead of spending my hard-earned money on physical therapies. Today, I walk 35,000+ steps per day, have lost 10+ lbs, and have ZERO back pain. Moreover, I sleep better, and I am more productive at work. I have a better concentration level to write logic and more abstraction level to design architecture diagrams that facilitate feature implementation. If you are a software engineer and wonder whether or not it is possible to code and walk, here you have your answer ;)

Waited over two months to purchase, wish I'd bought it sooner!

Due to the high price of this treadmill I held off on making the purchase for over two months. I spent that time trying to figure out how it would fit into my life and if it would actually deliver value. Would I be able to use it while typing, pointing my cursor, clicking, etc? Would I be motivated to use it regularly to impact my health? Would it just become an expensive piece of equipment that gathers dust? Well I'm happy to report that I've been using the treadmill every day since the day it was delivered about three weeks ago. It's not because I'm especially motivated to use it, but because it was so easy to integrate into my life without thinking about it. Just like I used to sit down at my desk every morning, I now walk at my desk every morning. But let's start from the beginning, how was delivery?

It was delivered in a large cardboard box strapped to a wooden pallet. This was initially overwhelming since it was so large and extremely heavy. Requiring two people to move into the house. But once the unstrapping, unboxing, and moving was over with, I began to feel happier about the purchase.

The standing desk was delivered in two shipments. One contained the legs and was delivered about a week before the treadmill, the other contained the desktop and was delivered a few days after the treadmill. The desk's legs are made from steel so they're very heavy. This theme of 'heaviness' was worrying, since I knew I'd be a challenge relocating the desk and treadmill if I moved or if I wanted to change it's location in the house. But it became clear why these solid, heavy components were necessary.

It took a couple hours to assemble and set up the desk and treadmill. I turned it on, began walking, and noticed the treadmill belt was making jerking movements instead of moving smoothly. This caused me to lose my footing, so be careful of this when you first get on. I read the manual (probably should have done that first.) And noticed you can tighten the bolts at the end of the treadmill to fix the jerking belt problem. I tightened them, and the issue was fixed immediately.

Once I began using the treadmill with the standing desk, I was impressed by how sturdy everything was. I am a 250lb 6'0 male, when leaning on and off the desk there is hardly any shake at all. Even when the legs are extended to their highest setting. And this solid build quality is evident in the treadmill also. There is no flexing, bouncing, or even shaking to the treadmill while walking.

These qualities along with the Unsit's wide walking area makes it feel extremely natural to walk on. I don't have to keep looking down at my feet and there's no unnerving wiggle that other treadmills have. I can focus on my work and forget about my feet.

But how difficult was it to get used to? Well, I set it to the highest speed possible which is 2 MPH. So I had to adjust how I use my keyboard and mouse to accommodate for the sway of my body while walking. There will be mis-clicks due to a jumpy cursor and typing mistakes due to jumpy fingers, but these mistakes only occurred less and less as my hands became accustom to working while walking. Now I can work for hours at a time without any struggles or frustrations due to the treadmill. I write scripts, edit videos, and do animation work with the same precision and speed I had before.

My final thoughts are that this is the best desk treadmill money can buy. And you get what you pay for. I've owned a $400 desk treadmill before but didn't use it since it was too narrow, too flimsy, and too impractical. Now, I use my Unsit treadmill every day without even thinking about it. I love that the app tracks my steps and although it could use some improvement, it's nice that the functionality is there. I'm averaging 25,000-30,000 steps a day because of this treadmill and I've lost 5 pounds so far without even changing my diet. So I'm excising, working my job, and preventing health issues from sitting all at the same time. This is a huge value-add to my life and I'm so glad I bought the Unsit after weeks of uncertainty.

Best Purchase Ever

For the last 4 years I have thought about getting a treadmill desk. I researched constantly and found UnSit. I saved the link, but never pulled the trigger. The next year I would do the same. Still the UnSit came always on top. Finally, I knew that I couldn’t just save the link one more year. My only regret…why did I not do this 4 years early. This was absolutely the best decision ever.

I worked from home, long before COVID, and found myself sitting for at least 12 hours a day. Now, in the last month, I have walked over 53 hours, and 66 miles. What a difference this has made in my life. I want to be alive a long time to watch my grandkids grow-up. The UnSit is going to help me do that.

Thank you!!!!!

The Unsit treadmill desk is my unfair advantage !

I've always noticed that I do my best creative problem solving and original thinking when I am in motion, but until I got my Unsit treadmill desk, most of my best ideas got away from me. Now, I can remain in a flow state of optimum thinking as long as I want, and the back and neck problems I had from years of being a psychotherapist are a thing of the past. Unsit is a great product and it's a great company to do business with as well. I only wish I had found them sooner.

Bad back cured - Now walking 5 miles/day

My journey began six years ago. I was experiencing lower back pain when sitting for long periods of time. I upgraded my chair to an adjustable Aeron chair. My new chair was very comfortable, but my posture remained poor and pain returned to my lower back.

Around the same time, I read several articles about how “sitting was killing us” so I decided to “save myself” and with a new standing desk. Wow! What a positive difference standing made on my lower back pain, but after a while, I started feeling aches, pains and stiffness in other places. Getting up out of my chair helped but standing turned out to be only part of the solution. I was committed to working on my feet, but I needed to add some movement as standing felt static and my legs ached.

Coincidentally, my brother’s company, ActivEd had produced a new program called WalkAbouts, an active learning platform for schools. WalkAbouts was further proof of the positive physical and mental benefits of moving compared to sitting and it validated my thoughts about moving while working.

So I started researching under desk treadmills. I wanted a treadmill that was built for slow speed walking. To fit with my desk I needed a treadmill wider than a traditional treadmill and much shorter. I thought I’d never find what I needed, until I came across the UnSit. In my first week with the WALK-1 Under Desk Treadmill I averaged 5 miles a day and I can already tell how movement solves the downsides to standing. I can do everything I normally would do at my desk while walking. The iOS app is a great motivator as it tracks your progress. Rob and the entire UnSit company have been awesome to work with!

One of the absolute BEST purchases I've made in a long time!!

I have been coveting the Unsit desk ever since I saw a demo a few years ago. This desk was unique in it's size, design, philosophy, and delivery. I was so impressed with the passion & science behind the product, the local family owned business, and the attentive customer service BEFORE I ever made the purchase. They were genuinely interested in my learning everything necessary about treadmill & standing desks and there was never any pressure -- just very helpful information. I learned that the disadvantages of sitting all day are FAR more than posture and lack of exercise. Read up on some of the latest science on the impact of long hours of sitting and it's quite compelling. The financial investment kept me hesitant at first, but now that I have finally purchased the desk and have been using it for 3 months I am SO HAPPY !! It is worth every penny and then some. It's rare when you feel that a single purchase has really changed your life. I'm in the software and RE sales business and I have spent decades and LONG hours in front of a computer. Now, what a difference in my work day, my mood, & my physical well being!!
There is a mild learning curve in the first couple weeks as I type and walk (conference calls and reading emails are easy, and fantastic to be walking and talking). I am notoriously uncoordinated, but very soon I had the hang of it and it's great. Gotta love a new motor skill to add to my list :) My Unsit desk is next to a large window so I get a nice perspective when I'm walking and talking, and but then I appreciate that I can get focused on my computer in an ergonomic way. I love that I can move the desk to different heights, and the treadmill moves at different speeds. The speeds are created for walking and working, so I set the dial a bit slower when writing/typing, and move it up when talking/reading. The UnSit App helps me track my mileage during the day. Wow. I hope that this kind of desk becomes the standard of the workplace.

I've been walking while working for 3 years

I've been walking while working for 3 years and have gone through several different brands of walking pads and the Unsit has exceeded all of those in features and comfort the wider and shorter design is so much nicer. I average 20+ miles a day and some of my other walking pads stopped working in pages than a month. I'm excited to use for several years to come.

Love this tredmill

Love this tredmill. Also got the stool so I can sit once in a while, and stand, and walk. Only challenge -- The treadmill is EXTREMELY heavy, and getting upstairs in my garage was very difficult. But hopefully that means it's well made and will last for many more years.

This treadmill is something else. Super comfortable. Silent. Worth every penny. There is just no competition to this. I have been walking all day, every day while working.
