I highly recommend the SewEZI www.seweziusa.com. We lived fulltime in a 30 ft travel trail and I used this fold up sewing table the whole time we traveled the USA. It fits right in a closet when not in use--has little wheels if you need to transport. It weighs only 23 lbs--has a large work surface 34X19. The sewing machine sits flush with the table top. The Fons and Porter May/June 11 issue has a picture of it on page 85.
We now live in a stick house and I'm still using it for my sewing machine table in our guest room. Hardly takes up any room and it is so cute! I recently bought the optional accessory tray and love it. So handy!
Wish I worked for the company I could make a bunch of money selling them. Ha!!!
