The spring-loaded push-down brakes of these rolling walkers are weight activated to help control the walker's movement. Push-down, weight-activated brakes are preferred for users with impaired memory or hand dexterity when squeezing a hand brake is too difficult. Many of the walkers also feature adjustable handles and/or seat height to fit individual needs. However, rollators can differ greatly in size, weight, color, weight capacity, brake type, design, wheel size and basket or tote bag size.
