FAQ / Mobility Aids

Frequently asked.

Answers to the questions clinical buyers and care teams ask most about this product category.

What's the difference between a walker and a rollator?

A standard walker has 4 fixed legs and must be lifted with each step — offering maximum stability for weak or unsteady patients. A rollator has 4 wheels, brakes, and usually a seat — better for patients who can walk steadily but need support over longer distances.

How do I choose a cane vs. a walker?

A cane provides minimal support and is appropriate for mild balance issues or unilateral weakness. A walker is indicated for moderate-to-severe balance issues, bilateral weakness, or non-weight-bearing lower extremities.

Are mobility aids covered by Medicare?

Yes — most mobility aids (walkers, rollators, wheelchairs) are covered under Medicare Part B with a qualifying diagnosis and written prescription. Coverage amounts and replacement intervals vary by device.

How do I adjust the height?

Stand upright with shoes on. The top of the handle should reach the wrist crease when arms hang relaxed. Adjust the legs to lift the device with the elbow at a comfortable 15–30° bend during use.
