So, I'm setting up a new apartment once I get to Japan next month. I bought some furniture from a JET in the area, which includes a single (twin) bed frame. The bed frame can be used with either futons or spring mattresses. I've slept on a futon before for about a week straight when I went to Japan last year, and it was super uncomfortable. I didn't sleep well. I wonder if it was because the futon mattress was too thin, maybe a thicker futon would be better?
Anyway, I would really prefer to get a spring (western-style) mattress, if possible. But I wonder if asking my supervisor to help me get that mattress to my apartment would be too much trouble for them? I'm not even sure if we will be able to fit it in their car. Will I be able to get the mattress delivered to my apartment same day? How much do single/twin mattress cost generally? I probably will get the cheapest mattress available.
If I do go the futon route instead, I will want to get one that is well-padded and comfortable. Something like THIS. I figure I can always layer the futon with extra futons or a memory foam mattress topper to make it softer if I need to. Does anyone know how much thick twin sized futon like this usually go for?
I realize I also have to worry about disposing of the mattress when I leave Japan. Is it easier to dispose of a futon mattress than it is to dispose of a spring mattress?
Thanks in advance
