I have seen a permanent version but not one that folds up. And it was in use at a home improvement store and not for sale. I was looking for something similar but settled for the black plastic storage shelves which I break down and bind with an elastic cord for transport.

Thanks trianglejohn. I may have to go that route. Time is running out before our first Market.

A Flea Market vendor that welds pipe has 2,3 & 4 step welded pipe stands. For those the back support legs are held in place by wing bolts and removed for transport (sort of like folded 3-leg design). There may be someone in your area that makes canopy frames that can supply these also.

I really like the 3 step stands for plants. Three stands provide a sturdy base for an 8-10' display. You will need to purchase 1x12" boards to length for each step also. For possible shipping call the vendor: Wm. Parry: 302-659-3680

I actually can weld so may try that design.
Thanks bmoser

See the link for the table I'm going to try. I bought four.
