I was having the worst sciatic pain when I was pregnant and was told by my doctor to buy a round donut seat to sit on. Needless to say I couldn't find one anywhere! I looked and looked and then I went to Rick's and found 3 to choose from! They were very decently priced and I am so glad that I bought it. It helped with my back and leg problems and I will definitely go back there for any other Medical supply needs that I might have.
