We just bought our very first travel trailer. NT 24BHS As i have been working on stocking up my camper one thing i am having trouble with is the bunk bed, the mattress is a fleece material and no removable cover. I have two young children 4.5 and 2 and do not want to ruin that. I am looking for a mattress cover I can put over those to preserve them. The bunk beds have a corner missing at the bottm where you enter the bed so regular covers dont work? Any suggestions?
