Well mine is certainly stable enough.....I used a 3/4" plywood as the top because that's what I had on hand - it's heavy! (I have mine in a carpeted room) Also I covered mine with the insulbrite which has just a little bit of padding and then covered that with a cotton twill. A friend has the purchased big board & recommended not using so much padding so that it could be used with a cutting board as well. HTH
