This is one amazing quality and handsome looking desk. Definitely takes three hours to assemble WITH an electric power drill. Do yourself a favor and buy a power drill if you don't have one. Otherwise be prepared to spend 5 to 6 hours assembling this. There are about 100 screws :) The top panel along is about 70 lbs. Assembly instructions are very good. When you assemble the draw slides, make sure you follow the instruction graphics to put the screws in the appropriate holes, you can easily mess this up and lead to more work later or uneven drawers. For me the toughest part was that when putting the top panel on, two wooden dowels wouldn't fit in nicely so I had to remove them, which is totally fine. The desk is still as sturdy as it needs to be. This desk is easily over twice of its price sold at overstock elsewhere. Very deep and large. Take a tape out and get a sense of how big it is by reading the dimensions on the product details page.
