I've found myself feeling underneath desk tops, and even getting on my knees to see the underside of card tables. Wheeler Wilson had some cabinets that really did not look like they would house a sewing machine.
But this one, if it had the top on it and everything folded up, unless you get a good angle, you won't see those parts. The designers did a very good job making it so they hide well. I keep looking at the needlebar picture and it's very hard to tell it's a removable top, at least from the angle of the picture.
