Wow! This is the first time that I'm seeing this post and I'm VERY impressed! This isn't just a great idea, it's also really great for people who need to sit while gardening, and those who are confined to wheelchairs.
Dave created a new Ideas Forum recently. If you haven't already posted an article about this, I hope you'll consider posting one there. I've read multiple posts from people asking for recommendations that work for wheelchair gardeners and this is just perfect. Hope you'll do it, or that you've done it!
