In response to the previous reviews, it sounds like the extra components are to be used with specific bird feeders as mentioned here from another brand of this cage:
Retrofit Cage Components:
* 13-1/2"L x 12"W, 19-1/2"L x 12"W, or 25-1/2"L x 12"W cage frame with 1-1/2" openings
* Cage Bottom (ships detached) attaches to feeder base with included hardware
* Includes threaded adaptor for securing cage bottom to our Clever Clean or Droll Yankees Clever Clean Tubular Seed/Nyjer Feeders
* Includes screws for securing cage bottom to wood or recycled plastic bird feeders
Easy to put together. Clear, and clean, directions with pictures made this gift a breeze to put together. My father in law is planning on buying a second swing to go with the one we got thin for Christmas.
Beat the shipping time estimate, customer service / package tracking staff were very responsive, and the actual glider by LuxCraft is awesome.
Beautiful chairs! Assembly was a little challenging. Instructions could use a few more pictures during the process.
Exactly what I expected. Comfortable. Easy to assemble.
