This kind of bed you are talking about is a combination bed, also called an apartment bed, which has been popular in the past two years. It most appears in the dormitory of university campus. This kind of bed breaks the long-standing clutter, gives the dormitory a feeling of being tall, and also creates its own independent space for students. I have looked for this kind of bed on the internet before and compared several. I found an old brand of "apartment bed" specializing in "continuous science and education" on the Internet. The style is really good, I like it at first sight! Now we are working together.
