I drooled over the Gypsy Balance Cushion for a long time but just couldn't justify the cost. I found something very similiar at either Walmart or Meijer. It is made by Danskin and it works just as well. It is a balance disk and it helps strengthen your core muscles. My sides and abs were sore for the first week that I used it but I have no problems now. It is sold in the exercise equipment area. The best part is it cost about $13-14!!!
