My husband and brother put this swing together and I didn't keep track of time but it didn't take too long. They said it was really hard to put together because the holes in the pieces did not align correctly. The swing will definitely have to be put in the ground with the included pieces (we haven't done that yet because it was really hard to screw them in the soil)  to do so because the whole thing will tip over. My daughter is calm but I know when her friends come over something will have to hold that thing down or else they'll all be flying off of it. I would say at most you can fit 2 kids comfortably, three squeezed together or one adult and one small child. Overall, I'm happy with the purchase.
