Now I'm curious... how do you function? Just sit on the floor?
Yes, most of the time. We have floor cushions and back rests (basically a chair with no legs) and small tables with legs about 8-10 inches in length. We sleep on the floor on a traditional bed called a 요 ("yo") that can be rolled or folded up. It's nice because it is very firm, warm in the winter (Korean homes generally have heated floors) and allows you to reclaim the floor space during the day.
We've had three apartments in Korea and none of them has had a closet. Most people buy either wardrobes or clothing racks. We have a two-level rack that reaches to the ceiling and holds all of our clothes (and my ukes) except for socks and underwear. Those are kept in a small set of drawers in a low chest. All other household storage is in plastic bins, sort of like the Rubbermaid totes you would see at Walmart.
Our current kitchen has a lot of cabinet space, but almost no counters. Any prep work you need to do is done on one of the low tables, either squatting or sitting on the floor. Like most Korean apartments, this place came equipped with a refrigerator and a range with gas burners (ours is fancy because it has 3 instead of the usual 2
) but no oven. We purchased a toaster oven, a microwave, and a shelving unit to keep them both on, making our kitchen the envy of all our expat friends.
I play my ukes while sitting cross-legged with a back rest, with my music notebook or my laptop on a table in front of me. It limits my practice time a bit, as it aggravates my sciatica and my legs tend to fall asleep. Other than that, it's a pretty comfy arrangement.
