Very nice pop-up canopy! Included with the canopy are solid side walls, weight bags, spikes with heavy duty cording and a great carry bag with wheels for pulling (great addition because this is heavy.) Very easy to put up, we did it with two people but with a little practice I believe it can be done with just one person. The fabric top and sides are constructed well and also heavy duty. Its important to use the spikes and weight bags if you plan to have this up for an extended period of time or on a windy day. The instructions are included and in with the canopy top bag. You will need to install the included wheels on the bag, this is very simple to do. The 12x12 is a great size to cover a large outdoor dining set with a good amount of extra room. I highly recommend this canopy, I am extremely pleased.
