A major drawback in my opinion. I don't know why a lot of electric tables scrimp in size.
I haven't ever worked using a (narrow) electric table, but I have received a few on them, and it was extremely annoying! I'm average size, and my arms didn't come close to staying on the table, I didn't like feeling like I was too big for the equipment. Plus, turning over felt like a scary ordeal for me-- and my therapist. It's bad enough getting half-asleep people to turn over safely on a wide table. Not to mention frail seniors, obese clients, handicaps........you might as well have then get off the table and get back on.
Being a therapist now, and thinking about my clientele, most of them would not "fit" on the table. Also, being able to place the clients arms in different positions is necessary for their comfort and the type of work I do. You can always monkey around with making loops with hand towels to hold a clients arm in anatomical position, but do you really want to fool around with that after paying a few thousand dollars for your table?
