I purchased this online and had it in my room for just under a month, but my cat didn't seem to relax in it. There are some peeling spots. The largest peeling spot was there from the beginning. Please search online for more details. There are no assembly instructions, but it's a snap-in type, so I think it'll be fine. Please refrain from purchasing if you are unsure. If you also purchase the cat-shaped bed I have for sale, I will sell both for 2800 yen.
