I have arthritis in both of my hips and knees, spreading to my back, and walking with a stick can be a real challenge at times so I wanted something to help me exercise and provide security against losing my balance. Although it seemed a bit large when delivered ( next day, and really friendly and helpful staff on the phones!) I'm so glad I bought it- there's minimal assembly, only takes a few minutes, and on the first use my posture improved immediately, my back straightened, my core weight felt much more natural, my walking pace was much faster and much easier! The seat easily takes my weight- I'm 150 kilos- and I feel very stable and secure walking with it? Even if you do as I do, swop between using a stick and using the rollator for exercise, it really is money well spent! As I said , it seems a bit large at first but don't worry about that, use it and enjoy a much better way yo get around safely!
