Best apparatus for my physical build and sure it could help anybody with just any one of these problems. I am a very large man, 5'9" and weigh 425lbs. I have osteoarthritis and my knees are shot. I have COPD. With all 3 of these issues, a regular walker helps me to get short distances, but my back hurts and I can't go very far without sitting and resting to catch my breath. With the OasisSpace I can walk much farther and I feel so much better walking straight up. I still have to stop and catch my breath, but all I have to do is set the brakes and sit down on the seat that's built in and then get back up and move along. I'm thankful for this product. It's awesome!
