When I was seven, my older brother and I got bunk beds for Christmas. My dad put them together. He also put together the bookshelves I got at ten, and the computer desk that Aunt Jean gave me that I used all through high school.
Freshman year, I had an entertainment center my roommate assembled for me, paid in beer. Sarah, my girlfriend senior year, bought us a rocking chair she put together while I was at class.
A couple years later when Sarah got pregnant I bought a bassinet. I built that myself while she rocked in the chair.
