Features including four wheels, hand brakes, padded seat, backrest, storage bag, and foldability make the rollator a better choice over traditional walkers. Of these features, the four-wheel set-up is the most significant advancement in upright mobility. Rollator wheels are plastic. But rubber wheels work better on smoother surfaces. Since rollators assist people with deficiencies in strength and stability, the hand brakes and locking devices are critical for controlling the walker's speed and stopping ability, particularly on ramps and downhill terrain. Unlike traditional walkers, the rollator users can sit in a built-in chair and carry more items in the storage bag. In addition, other rollator features like the Molded General Use Wheelchair Seat Cushion make the walkers more comfortable and convenient for the user.
