Mattress top for aero bed?

I have just moved and have not gotten a regular mattress yet. I am using a full size aero bed and the only problem is with the material the top is made of. My pj's stick to it making it hard to move around. If i get a fitted sheet or a mattress top will that help? It is one of the raised beds so i don't think i will have a problem with it fitting, i just don't want to waste money if it won't help. Thanks
