Single Beds for Adults

Hi All, I just got Discover University, and I'm making over dorms and things, and want some single bed Custom Content that isn't child-like or too floral-ly or quilt pattern-y solid colours are nice, and so are some patters, just not the too flamboyant or childish ones.

At the moment I am looking to have a focus on wellbeing, so some linen fabric looking beds or wood look beds or neutral but light tones are good but not essential.

Just wondering if anyone can find any or suggest some sites, thanks.
