Hi littlerachet

Sorry no one responded to your post - We are usually pretty good about responding but your query just missed out.

There are a large variety of collars available and if this is the right thing to do in the case your partner, getting a really comfortable one is important as he would be wearing it a lot of the time and for a long time. Lightness but resilience, comfort with no areas of friction between the collar and the skin, good ventilation (they can get hot and sweaty) are all important points.

Here is an example of a database that includes a number of products. It is good to see a picture of it before approaching the company

AbleData: Products

Have you sought professional help over this? A neurological physio who deals with the sorts of conditions that your partner faces should be able to give you sound advice both about the collar and about appropriate exercises to improve stability of the neck/trunk. I would be reluctant to give you such advice without having fully assessed your partner's needs.
