some are more portable than others- when looking you need to do some research to see if the one you are looking at is easy to set up/tear down or not- some are made to be put together and left= some are made to set up=use & tear down.
i know a couple ladies who have ones they bring to the sewing group meeting- takes minutes to set up- it gets used during our 2-3 hours= then is back down and in the car.
check out the flynn frames too.
