I LOVE these chairs and I almost didn't buy them because the description said "adult assembly required".  I had visions of installing hinges and inserting slats. Boy, was I wrong. The only assembly required was to unfold them.  Thats it. They arrived fully assembled. 
The construction is very solid as well as very comfortable. I love the fact that they have armrests! I am especially pleased that they coordinate nicely with my existing (and ancient) teak furniture. I am extremely happy with them and love that they are made out of solid eucalyptus wood. They should age very gracefully as we enjoy coffee in the mornings and sunsets in the evenings from our now completed front porch.
