Wonderful product
I purchased this product for a family member, who has to go to dialysis three times a week for approximately 5 hours at a time.  She has been on this schedule for the past 6 months and had still not become accustomed to sitting in the dialysis chair for this length of time.  I came across this cushion and saw that it had great reviews so I decided to purchase it for her in hopes that it would make a difference.  She says that it makes a big difference in her comfort level and she is able to sit there for the required five hours without the discomfort to her tailbone she had before.  The only qualm for her is that it is pretty heavy, at almost 10 lbs., but I think that's the reason it works so well. All in all, it was well worth the money.
