Kate,
Thank you for posting this information. I didn't like the quilt suspension system that I was using, so you inspired me to build one out of pvc today. I had to configure mine a little differently so that it would work for my space. I think that I may need to push the tubes into a few of the connectors a little more. I haven't tried it out yet, but I like the look of it.
I have a few questions please. Does your frame wobble a little when you use it? Did you use any adhesive in the joints? If so, what kind? Have you made any modifications since you first posted this?
Thank you!
Jill
