Assembly was fairly easy if you are handy. My hubby (75 yr old) did it by himself. The only help I gave was helping tighten the roof nuts from underneath and help with hanging the screening  curtains.  Instructions could be improved with actual explanations for some of the steps and not just pictures. There are no maintenance instructions with regards to the privacy curtains and screens. The screens need a way to keep them from billowing in or out of the structure all the way around the bottom. We added grommets to the fabric on the corners of the screens and tied the bottom corners around each post, and also figured out a way to attach the middle sections to our wood floor to help stop them from billowing so much. We will probably do more once we see how it handles our varied weather. We live in a snow area so are hoping the structure withstands our winters as it claims to be able to do. All in all we are happy with our purchase and are looking forward to many relaxing evenings in it.
