Our house has an apartment on the lower level that was for my mother and step-dad. He's passed away three years now, and my mother lives with my sister. Their bedroom is now a guest room/my sewing room. I love it. When the family comes over not one of the kids gets into any of my stuff. They only use the tables as desks. So far so good! I have two inexpensive foldaway tables I got from Costco. They are at right angles. I think if the tables were heavier, though, I wouldn't feel vibration when I sew.
I keep the ironing board out, but when family is here I put it away.
Happy sewing!
