The Drive Medical 10257BL-1 4 Wheel Rollator Walker has a seat height of about 22 inches. According to the manufacturer's description, this walker is designed to be both comfy and functional, which makes it a popular pick for people needing reliable support for getting around. The seat is padded for extra comfort, and there's a handy storage pouch under the seat for carrying personal items during your outings.

Our research shows that this rollator is appreciated for its sturdy and stable build. Many folks have found it very helpful, especially for recovery after surgeries, including knee surgeries. It also has ergonomic handles and easy-to-use hand brakes for added safety. The handles can be adjusted between 31 and 35 inches, which works for a range of heights, but taller people might find it a bit lacking. There's a suggestion we found for adding another notch to better accommodate taller users.

While the rollator is tough and reliable, some areas might need improvement. For instance, a few people mentioned that the handles could use more padding, especially if you'll be using it for long periods. Also, some have said the frame around the seat can be a bit sharp, so a pillow might help if you plan to sit often.

Overall, if you need a rollator with a convenient seat for resting, smooth maneuverability over different surfaces, and dependable brakes, the Drive Medical 10257BL-1 is a solid option. It also folds easily, making it great for travel or storing in your car.

If you're recovering from knee surgery, you might want to consider extra padding for the handles or a cushioned cover for the seat for added comfort.
