Earthlite Jumbo 3/4 Round Bolster
Pay attention to the dimensions when considering this bolster. It is 'jumbo.' I wanted something bigger, and I thought with the flat size it would work well for under the ankles and knees. It does work well, but it is large. In fact, I have found it is too big to use with my 'regular' clients. I won't return it because it has a purpose. This bolster is great for clients coming in with moderate to severe back pain that need higher raised knees to alleviate the pain so I can work on them comfortably. It is really too large for ankles. The product description mentions for use on neck. I won't use it there. I couldn't imagine that being comfortable.
So the smaller bolsters are a better choice, especially the fluffy bolster. But, if you are a therapist looking for extra cushioning to supplement and support a specific client base, this is your bolster.
I also think it could be used well to sleep on your back if you need it to alleviate back pain...for non-therapists.
