Hi Jennifer,
I do not have company that makes bed or mattress but I have helped orphanages with safe beds for older kids and cribs for babies. So I have kind of seen it all in this area. I have guy who made some strong metal based bunk beds that you can use as well but again it take time to get it ready so just not sure how much time you will have for such.  But you kind of have to know what you really want and help them understand, such as size, height/width. And the mattresses, the company that cuts the mattresses accordingly to your request both thickness and height/width normally they have the synthetic leathers there but sometime they say they are out if it only have simple cloth. You can request to be covered with such there or bring the SL from other place (Merekato) the biggest shopping center and I would by the SL there so, get the best quality, so are very thin and can tear very easily. If you have a very good local driver then it is not big deal you can go there that plus bed sheets, other stuff that you may need for the refugees. Hope this is helpful.
