I put this together on my own, my husband isn’t much for diy projects. It took me probably 3 hours because I was chasing my youngest around while trying to assemble it correctly. The saucer swing itself was so much larger than I expected which is nice, both my boys can actually lay on it comfortably. It is definitely more of a relaxing slow swing, very safe! In my opinion, it won’t ever swing high enough to need to be cemented in the ground, but if you prefer to have that done for extra safety measure, go ahead! It came with all of the tools and parts needed, I didn’t run into any missing parts or broken parts or anything. Very pleased!
