Review on Versatile EveryMile Aerobic Stepper With Adjustable Height - Non-Slip Workout Step Platform For Exercise, Fitness And Sports, Includes 4", 6" And 8" Risers For Full Body Training by Alfred Friedrich

Although the extra risers store underneath it, you can’t have them there while you are using it because they are slightly taller than the riser and that makes it rock back and forth. I’ve only used it on the shortest height so far but it works as intended. Nice size, non slip and doesn’t hurt your palms when doing push ups on it. Would be perfect if the risers were 1/8” shorter when in the storage position.
