Thanks for all your comments and advice. I really appreciate it. Today for the first time I took it into town with me and found it an absolute boon. I walked upright, quicker (or so it felt) even though people passed me. When I thought oh gosh I need to sit for a while I put the brakes on and sat down. It was heaven. Frances, maybe the brakes need adjusting, if you can’t do it yourself take it into a mobility shop and ask them to help you. When I applied the brakes the rollator would not move and I was able to sit down safely. The other tip I would suggest is just think of it as a supermarket trolley and walk tall. I love mine it gives me total independance and no wheelchair, the only thing I did find is that my poor legs really ached afterwards as I’ve started using muscles again that had forgotten what to do. I look forward to my next trip out.
Take care all of you and thanks once again for your replies.
