These are really nice.  We have the metal seat ones, too. The seat on these is slightly larger than the metal seat version.  We liked this, because it allows for the compact size, yet maximizes the seat space.  Most adults will feel the side brackets at your back Lowe hip while sitting.  If you are more well endowed, youll like feel it greatly.  However, its not terrible.  Im a fit guy, and knew the chair I was getting and was happy when this wooden seat version was slightly larger than the metal version.  So gave it 5 stars.
