What Specs Should Product Managers Require so Users Can Safely Navigate a Single Step or Curb with Rollator?

For mobility product developers, specifying the right features isn't just a design decision—it's a safety imperative. To safely navigate a single step or curb with rollator, the rollator must be engineered with precision. This article details the essential specifications product managers should demand during design, sourcing, or vendor selection to support safe curb navigation in real-world environments.

• Front Wheel Diameter: Minimum 8” for curb clearance; larger wheels recommended for uneven urban environments.

• Rear Wheel Support: Must support 300+ lbs dynamic load, with sealed bearings to reduce friction.

• Material: Polyurethane or puncture-resistant rubber with tread patterns for curb traction.

Rollator frames should enable the user to safely navigate a single step or curb with rollator without requiring a full lift:

• Frame Angle: 5–10° tilt resistance; testing should simulate curb tilt and descent.

• Base Width: Not less than 22” to reduce tipping risk.

• Curved Support Bars: Recommended for enhanced grip and redirection of downward force.

• Brake Type: Dual hand-lever friction or drum brakes with adjustable tension.

• Brake Torque: Should withstand up to 100 lbs stopping force while on incline.

• Compliance: Certified to ISO 11199-2 or equivalent national standards.

• Curb Assist Pedal: Located near rear wheels for caregivers or users to step and tilt.

• Reflective Markings: Useful in urban and dim-light curb crossings.

• Grip Texture: Anti-slip molded rubber; must retain grip in wet conditions.

Knowing how to safely navigate a single step or curb with rollator is part user technique, part engineering. Product managers must collaborate with design and QA to specify reliable components, test for curb resistance, and validate user safety metrics in both lab and field conditions.
