Yes. I have very limited/cheap furniture. Almost everything I own comes from discount stores or thrifts. I don’t have an attachment to any of it. I’m debating going the Peace Corps so I don’t really want to own anything that I’ll have to pay to store.
Something that I’ve found works well for sleeping is a tatami mat and futon mattress. It’s best if you can air out the mattress and mat outside occasionally. But you can fold and roll both. You can also stack up layers of those $4 Walmart fleece blankets to adjust coverage.
That is one of the techniques I was taught in a sketching class.
