This is the backrest, in this picture, I already removed the cover.
Brand en type: Therapeutica Back Support.
This backrest is sold in 3 sizes. I have the largest one ( "Large"), which is too small.
With additional polyether foam I was able to make it fit my back.
It turned out that the cover was easy to remove.
But the foam felt greasy. With a warm soapy water, I tried to clean it as much as possible.
This backrest weighs about 1.9 kg.
If I go somewhere, I would like to carry the backrest like a backpack.
But it is not easy to fasten the top to something.
