I purchased the exact frame not too long ago because I was finding that my body mechanics were really suffering as I was trying to hand quilt my first queen size quilt. It was just not comfortable for me to use a large quilting hoop frame in my lap with so much fabric. Now I can sit with a good supportive chair and angle the frame to the right height for me. I also like this because it's easy to move from room to room and it's easy to take a part for travel.
I chose this one also because I didn't know how much I will be hand quilting in the future (after this quilt is done...though it's going to take a really long time so I'll definitely will get my money's worth!) and this was much cheaper than so many others that I looked at. Hobby Lobby also carries these and I used a 40% off coupon for it.
