Sunny Health Curved Step Climber Review: Long Stride (2026)

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

Sunny Health & Fitness built the Curved Step Climber around a longer stride than the short-throw steppers that fill the low end of home cardio. It has a 71 cm (28 in) curved stride, four incline angles from 35° to 50° and a 150 kg (330 lb) weight capacity, and it carries model number SF-S023051. One caveat shapes this whole review: no independent test of this model turned up in research, so the performance picture comes from Sunny’s own specifications.

Amazon.ca lists the model at $449.99 CAD in October 2026. The Canadian detail that matters most is the warranty. Sunny’s warranty policy says it applies to the United States domestic market and covers products bought in the United States, plus orders placed on sunnyhealthfitness.com and shipped to Canada. It doesn’t say whether an Amazon.ca purchase qualifies, so Canadian buyers who want the 1-year frame and 180-day parts coverage should confirm eligibility with Sunny before ordering.

Key Specifications

Sunny Health Curved Step Climber Stride & Incline Range

The headline claim is the stride. Sunny says the curved path gives a smoother, more natural climbing motion than traditional step climbers, with glide rollers along the track. For scale, Sunny’s foldable SF-S024035 lists a 55 cm (21.5 in) stride. How the curved path actually feels is Sunny’s description alone for now.

The four incline angles are the other adjustable piece. Sunny says they target different muscle groups, naming glutes, quads, calves and core: the steeper settings shift the emphasis toward quads, calves and core, and the shallower ones help engage the glutes more. That is manufacturer framing rather than measured muscle activation, and the page lists no resistance levels, so incline is the only difficulty control advertised.

Build, Footprint & Setup

Sunny rates the frame for 150 kg (330 lb), the same rating it gives the foldable SF-S024035, and the machine has transport wheels for repositioning. It weighs 23 kg (50.8 lb), well above the 13.3 kg (29.3 lb) of Sunny’s foldable climber.

Sunny lists shipping dimensions of 123 x 25 x 42 cm (48.4 x 9.8 x 16.7 in), a long, narrow box. The page advertises no folding mechanism, unlike the foldable model, so plan on a permanent floor spot rather than closet storage. It gives no assembly time or noise rating either.

Monitor, App & Tracking

The built-in LCD shows time, steps, calories, total count and steps per minute. A Bluetooth link pairs the machine with the SunnyFit app, which Sunny says carries trainer-led workouts, scenic tours and challenges with no membership fee. Heart-rate tracking needs a wireless monitor that Sunny sells separately.

How Does It Stack Up Against the Competition?

The table sets the Curved Step Climber beside three rivals. The first is Sunny’s own foldable climber, the space-saving alternative. The second is the MaxiClimber vertical climber, which BarBend picks as its budget stair climber in its classic version; the column shows the model MaxiClimber sells now in the classic’s place. The third is the Bells of Steel Blitz Stepper, a curved-rail climber that Garage Gym Reviews tested and that costs more than four times as much on Amazon.ca in October 2026 ($1,999.99 CAD against $449.99 CAD).

Is the Sunny Health Curved Step Climber Worth It?

For Canadians who want longer, low-impact stair work at home without paying for a four-figure machine, this is worth a look. The gap to weigh is the warranty: Sunny’s text names Canada only for orders placed on its own site, so asking Sunny’s support to confirm coverage for an Amazon.ca order is a sensible step before buying.

Shoppers short on floor space are better served by Sunny’s foldable SF-S024035, which trades stride length for a folding frame. Anyone who wants 15 adjustable resistance levels and a climber that Garage Gym Reviews has tested should look at the Bells of Steel Blitz Stepper, which that outlet scored 3.86 out of 5 and lists with a lifetime frame warranty, though its tester found even the top resistance setting a little light.
