This weekend, I thought: I'll put together Nathan's new bedroom set. A bed, a desk and a bookcase. Shouldn't be too hard. I checked IKEA's site and they said 30 minutes for the bookshelf, 90 minutes for the desk and the same for the bed. (These times are always lies since they depend on having someone who is familiar with the products.)
So I thought to myself: probably an hour for the bookcase (I've done a lot of those) and 2-4 hours each for the desk and the bed.
Actual assembly time: 1 hour for the bookcase, 8 hours for the desk and almost 10 for the bed.
I'm wiped and I have blisters on my thumbs from Allen Key overuse. But Nathan loves his new bedroom set, so that's a win.
