Took 1 person about 3 hours to assemble, the instructions are super clear and we had to restart the spring arrangement to have it align with the net poles. But aside from that it's an awesome product. I like how the net is inside preventing little feet to access the spring.
I would recommend this product, kids and parents are jumping away like crazy.

Pros: Sturdy, safe, nice padding
Cons: Instruction booklet needs to be more accurate
