Made of aluminum framing, the shipping may bend the frames as stated in other reviews, but a little coaxing makes them fit. Comes in several pieces, in a rather large box. Setup took about 3 hours. Good structure, solid. They don't exactly fall into extremely comfortable category, as the cushion angle is a bit steep for "relaxation posture", but it's really a minor gripe. We use them a lot. Would recommend.

Pros: Good structure, inexpensive
Cons: Steep back angle makes for a less comfortable experience, minor bending during shipping
