Non-slip surface is the only such on Amazon
I had bought the Drive Medical (brand name) walker storage tray. That brand was recommended to me by a physical therapist so I thought it would work well, and I especially liked that it has storage.  I was so disappointed it did not fit! I had to return it and shop some more. This walker tray does not have storage, but it does fit over the walker's handles, and can be easily lifted off to be a lap tray. But it doesn't fit all the way down the handles to settle on the front railing so, the tray isn't flat nor stable. The non-slip surface is great. It's the only walker tray I saw on Amazon that has a non-slip surface.
