We ordered 6 of these and they came quickly and were extremely easy to put together.  We found them to be very comfortable.  We decided on the product instead of the Trex after I read online reviews.  I had seen the Trex material before and liked it so I assumed this would be comparable.  If I would have been able to see these before the purchase I would have gone with the Trex.  I don't care for the material.  They are a bit wobbly once assembled but that could be due to the fact they fold so it wasn't a huge concern.  We thought the edges on the seat were a bit sharp but used a fine sandpaper to smooth them and it worked great.  Pros: Easily assembled, comfortableCons: Material, bit wobbly
