Arm Rest Recommendations

Hi George. So you put it on your guitar each time you play?  I haven’t ever seen someone use a temporary one so am interested.  My last 2  have had permanent arm rests?

Thomas Viloteau (tonebase instructor) makes one called "le support" https://www.lesupport.co/en it is very secure but large and somewhat cumbersome. But if you don't mind the size it's very adjustable and very solid
