It took three very handy guys (an engineer, mechanic, and designer) a whole day to put this thing together but they were very pleased with the instructions, the pictures, the labeling of the items, and even the hardware - which was top notch and easy to work with as opposed to cheaply made. We live in a dry sunny area so we went ahead and sealed the wood further even though it's beautifully stained, which added to the work load. This playground set is beautiful and not too massive. We look forward to many years of fun!
