A very simple inexpensive way is to get a folding table available anywhere, could be any length, mine is 8'. The legs on the table do not come straight down, they have a bend in them near the bottom. My husband bought some PVC pipe, cut 4 pieces the same length and I slide them over each leg of the table. He made it as high as I wanted for comfort. If I don't want the height, I simply take the PVC pipe off the legs of the table and can use it if all my family comes to dinner and I need more seating space.
