A major problem with using a walker is carrying things. You can balance certain things on the seat – but they tend to fall off. You can put certain items in you bag or basket – but not liquids in cups.
Here’s a neat solution – a tray that you add to your walker. It slots over the handles.
Feedback is generally good on this. It’s cheap and effective.
The major negative point is that it doesn’t fit all walkers. Check before you buy.
