In Korean dramas, the floor is paved, and there is no cushion, so it is not embarrassing.

Koreans, like Japanese, learn from China's ancient wooden beds, which are relatively hard, and gradually develop into tatami-like beds and put them directly on the ground. Watching Korean dramas 20 10 years ago, we know that they used to sleep directly on the ground under a quilt, and they were used to it since childhood, so there is nothing wrong with it. Sleeping on a hard bed is also good for the spine. I hope it can be adopted.
