A walker normally has no wheels or two front wheels and is lifted or pushed with each step. A rollator has four wheels, hand brakes, and usually a seat, allowing it to move with a more natural gait.

A Nimbo positions the frame behind the user instead of in front. This design can encourage a more upright posture and is commonly used for supported gait training.

A standard rollator cannot be used as a wheelchair. Convertible models such as the Nitro Duet can change from a rollator into a caregiver-push transport chair.

A hemi walker is designed for someone who can reliably use only one hand. It provides a wider and more stable support base than a traditional cane.

Most four-wheel Drive Medical rollators, including many Nitro models, include a seat and a storage bag or basket. Features vary by model, so check the individual product specifications.

Replacement wheels, glides, trays, baskets, and other accessories are available for many Drive Medical walkers. Compatibility should be confirmed using the walker model or serial number.

Many standard Drive Medical rollators support up to 300 lbs, while heavy-duty models may offer higher capacities. Always check the specification table for the exact model.

A folding two-button walker generally collapses flatter and weighs less. A lightweight or carbon fiber rollator may be preferable when the user still needs wheels, brakes, and a seat.
