I have a lap hoop that I love, but it's no longer made. One similar to mine would be the Grace lap hoop, which gets very good reviews:

All of the hoops -- the Quilting Thimble lady hoop and the Grace hoops -- swivel and have very little in the way of the underneath hand, so in those respects they are very comparable. The difference is that with the QT hoop, you sit with your legs on top of the stand. With the Grace lap hoops, the bottom part sits on top of your lap. I am a bit old and clumsy, partial to comfort, and didn't think I would like to have my legs sitting on top of wood. That's one of the reasons I went with the type that sits on top of the lap. As I said, I love mine. Having it sit on top of my lap is not a problem at all and both of my hands are free to quilt. I would never go back to juggling a plain hoop, and I think I prefer a lap hoop to a floor hoop. A floor hoop would always be in the way of someone or something in my house.
