Hi, I use a 6 ft., hard plastic sort of material, folding table that can be bought at sams club, costco, walmart, and Lowe's even have them...I use it for cutting, and sewing. I also have a 4 ft one, I will use for the embroidery machine.
I use a computer chair, that raises, and lowers, a cheaper one at that, and keep it at it's highest, when sewing. My back doesn't hurt any longer, since I found this by accident. My wire fox terriers play, under my feet, and they dropped my chair one day, to the lowest point. I raised it to the highest, by mistake, and liked it. Try that.
