In the world of the novel

In the world of the novel, bedding from Earth is incredibly expensive. In a regular estate, just buying a few pieces would be enough to empty the warehouse. However, that only applies to lands where leadership hasn't changed and hasn't undergone integration. In a place where the number of pioneers and civilians has significantly increased through integration, there's little that can't be obtained. Especially when it's a large community formed by the integration of more than ten territories.

While it would put a lot of financial pressure on the community, preparing bedding for everyone should still be possible—assuming taxes are collected properly. So, while others might be surprised by their wealth, it shouldn't be shocking to the point of disbelief.
