Sunny Health Folding Treadmill Desk Review (Honest Take)
Looking for an affordable, space-saving treadmill that can handle both walking and running—and still work with a standing desk? The Sunny Health & Fitness Slim Folding Treadmill (also sold under the Asuna name) checks more boxes than most compact treadmills in this price range. Below, I’ll break down how it performs, who it’s best for, and how you can realistically use it with a desk.
Quick takeaway: This is a solid, heavy-duty folding treadmill from a reputable brand. It’s easy to set up, powerful enough for real workouts, and includes a few nice extras you don’t usually see at this price point.
Sunny Health & Fitness Slim Folding Treadmill – My Experience
Most slim, fold-flat treadmills are designed for slow walking only. That’s where the Asuna folding treadmill stands out. It supports speeds from 0.6 up to 8.0 mph, making it suitable for everything from casual walking to light jogging.
The 2.5 HP motor feels noticeably stronger than what you’ll find on most under-desk treadmills, and the built-in shock absorption helps reduce joint impact—especially helpful if you plan to use it several times per week.
The upright console includes built-in speakers, a tablet holder, and a media port so you can charge or connect devices while you walk or run. It’s a small thing—but it makes longer sessions much more enjoyable.
Can You Use This Treadmill Under a Standing Desk?
Short answer: yes—but with limitations. While this model works great as a workout treadmill, it’s not a true under-desk treadmill. The arms must stay upright to operate the machine, which means it won’t slide fully under a desk the way flat walking pads do.
That said, you can make it work as a walking workstation with the right setup.
What you need: an electric standing desk that’s wide enough to straddle the treadmill and tall enough to clear the console. Being able to raise and lower the desk with a button makes it easy to start or stop the treadmill without crawling underneath.
While you won’t see your stats during work sessions, you can review distance, time, calories, and steps once you raise the desk back up.
Heads up: If you plan to walk while working every day, a remote-controlled option like the UREVO foldable treadmill is often easier to manage.
The Asuna works best as a daily fitness treadmill with occasional desk use.
Folds Flat for Easy Storage
One of the best features is how compact this treadmill becomes when folded. At just over 5 inches tall, it slides under a bed, into a closet, or against a wall without taking over your space.
If you’re setting this up on carpet, a treadmill mat is a smart add-on. It protects the belt, reduces dust intake, and helps the motor run more smoothly over time.
