KingSmith (WalkingPad) WalkingPad C2 Mini Folding Walking Treadmill vs Sunny Health & Fitness Slim Under-Desk TreadPad (SF-T7945SMART)
Which should you buy? Our verdict on both, pulled from our full The Best Under-Desk Walking Pads: 4 Compared (and One to Skip) comparison.
The WalkingPad C2 is the best all-rounder: slim, genuinely foldable, quiet and smart enough to walk hands-free while you work. The Sunny Slim TreadPad does the same core job for less if you don't need the folding trick or auto speed.
KingSmith (WalkingPad) WalkingPad C2 Mini Folding Walking Treadmill
Buy itThe slim, fold-in-half pad that vanishes under a couch and just works, day after day.
- Folds 180 degrees in half and is only about 5 inches thick, so it slides under a bed, sofa or standing desk
- FootSense auto mode nudges speed based on where you stand, which owners say makes hands-free walking effortless
- Runs quietly enough for calls and video meetings, and needs zero assembly out of the box
- Top speed tops out around a brisk walk, so it's not for jogging
- No handrail means unsteady users have nothing to grab
Sunny Health & Fitness Slim Under-Desk TreadPad (SF-T7945SMART)
Buy itA no-drama, low-profile pad from an established brand that nails the basics for less.
- Genuinely low-profile design slides under most desks, and built-in transport wheels make it easy to reposition
- Simple LCD plus app tracking covers time, speed, steps, calories and distance without fuss
- Backed by a large, long-standing fitness brand with accessible support and parts
- Walking area is on the shorter side at about 39 by 14 inches, which taller users notice
- Walk-only speeds and a basic remote; no auto position sensing
