thats a good question, that I have never thought of before. I guess that you could use one with only one arm. You would need to hold on, unless you were to make some additions to the swing. I suppose you could install the swing over your bed. That would make it only 1 foot or so above the surface, making the fall a safe one. And if your swing was able to spin......that would be some good times.
I have the pleasure swing. It is a high quality item. I have not had one problem with mine in the 3 years we have had it.
