This play structure is sturdy and fun. My four year old got the hang of it quickly. It's nice that the sides have differently spaced holes/handles. Some are too far a stretch for him now, but he'll be able to conquer with a few more inches on him.

Overall, assembly was reasonably easy. I completed about 85% of it before my husband was able to help me. It took about 2-2.5 hours total. Probably the most frustrating part of assembly was sorting the hardware, as there is seemingly no rhyme or reason to what is bagged together.
