My husband bought (inexpensively) this table at a one-stop-shopping (Fred Meyer) and added the top apron or skirt (I think it's called one of those) to raise the height for my purpose. I'm only 5'1" so it didn't have to go up much.
The table is 30 x 48 x 33 tall and the mat is 24 x 36. I love this size....I can walk around it if I want so I don't have to move my fabric and I can reach across it. Now and then I wish it was bigger but not often. I keep it in the center of my room and it does not take up a lot of space.
