What a good idea! I've just done the survey and put only 2 responses because the others aren't a problem for me. I'm not quite elderly - 68.
I see that filling and emptying the compost are together. But filling is usually a matter of taking the lid off and dumping in a bucketful or trugful, which isn't hard. Emptying can be hard because you're either trying to lift stuff out of the top at an awkward angle, and the spade/fork can't pick up much because of the length of the shaft in a narrow space, or you're bending and shovelling it out from the small door at the bottom. In theory you can lift the dalek off the compost, but I've never managed it.
My favourite would be a lidded and bottomless rectangular box with a removable front, say about 1.2m high and 1m wide, though maybe a variety of sizes to suit different requirements. Bigger would be great but not many people have room. Wood is nice but plastic is lighter and easier to move.
Hope this helps. Good luck!
