Overview
Compact stair stepper and climber from Sunny Health & Fitness, model SF-S024035, with adjustable step height from 8.9 to 23.5 inches, 21.5 inch stride length and four handlebar height positions.
This machine has no resistance settings of its own; intensity comes entirely from bodyweight and how far the user extends the step height and stride, making it a stability and endurance tool rather than a load-adjustable trainer. It connects to the free SunnyFit app for tracking and guided sessions, including AI-generated plans based on entered body metrics, though that pairing is a software feature rather than a hardware one. The listing's own description text references a different model number with resistance bands, which does not match this bands-free SF-S024035 configuration, worth confirming before ordering.
- Step height adjusts 8.9 to 23.5 inches
- 21.5 inch stride length
- Four-level adjustable handlebars
- SunnyFit app with AI-generated training plans
Who it's for
Fits anyone wanting a compact, low-cost stepper for legs, glutes and core in a small footprint, from beginners at a shorter stride to more advanced users extending the range. Not the right pick for someone who wants built-in resistance levels rather than a bodyweight-only climb.
Pros and cons
- Wide adjustable step height range from 8.9 to 23.5 inches
- Four-level handlebars fit a range of user heights
- Free SunnyFit app adds tracked metrics and guided sessions
- No resistance settings; intensity depends on step height and stride alone
- Seller description text references a different model with resistance bands
Performance notes
Step height adjusts from 8.9 to 23.5 inches and stride reaches up to 21.5 inches, so intensity is controlled by how far each step is extended rather than by any resistance dial. The four-level handlebars adjust separately for user height, and the SunnyFit app layers metrics and guided programs over that bodyweight movement.
