EarthLite Fluffy Bolster
This bolster comes close to being the most perfect. I have a private massage practice, and I also supplement my time working for a massage chain. This bolster may not be 'fluffy' like a pillow, but it is definitely not like the traditional harder bolsters. It softly supports the knees and ankles when I work on clients and has enough give that I don't feel the client is too high or too support. I don't think I would want anything softer that this. If I did, I would just need to get a feather pillow. It is easy to clean and it has lasted many years with proper care. Make sure you clean it after each use in case you get any kind of product on it. Otherwise, it will start deteriorating at the seams. The ones I use at work that multiple therapists use start to look worn after three years.
