Regarding assembly, these chairs were fairly easy to put together.  We did not have to obtain additional parts, and used what was supplied along with the chair.  They fold for easier storage, although these chairs are still big, even folded up.  But, if you're a smaller or shorter person, you might not be able to touch the ground with your feet.  I'm disappointed in that because I carefully used the measurements supplied in the product description, then compared them to the measurements that I have for some adirondack chairs I'm planning to replace with these and they were nearly identical.   These chairs have a higher rise, especially where the back of the knee land, causing my feet to not touch the ground.  I'm 5'2, so that should give you some idea of whether your feet might touch the ground.  The chair is perfect for my tall husband, but I'm uncomfortable.
