When my dad passed away, my mom was left on her own in the nursing home. She was literally blind, couldn't walk and was totally reliant on the staff from the home.
I wanted to get her a double table that she could pull over her chair when she was seated, as the staff brougt drinks etc and put them on a table too far from her to see.
Anyway, I did some research on the sort of table she needed, but couldn't find anything that I could get off the shelf.

I stumbled across a chariity called Remap, and got in touch with them for advice. They said, "if you can't find anything suitable, we would be willing to look at your requirements and if you are correct, we would be willing to make it for you FOC". I sent the info in and they made it and installed it for my mother. They are a charity and do lots of bespoke things for people in such needs. However, if you can buy what you are looking for from a shop or dealer etc, they do not help.

Just thought it might help, if somebody needs something special to help them, have a better quality of life. Obviously they are UK based.
