Took my husband and I 2 days to put together but we are still married...so there's that. What slowed us down was that all of the lumber was not labeled - about 25 pieces were not labeled. I would recommend organizing the pieces and putting them all in a line. It is so much faster to find what you need that way. I would do the same thing with all the hardware. Once together it's a very sturdy set that my kids love!!
