Bedbugs

So the other day I posted a picture and y'all said it was a bedbug that I found. I moved into my living room washed everything in hot water and I threw my bed away. I'm wanting to rent a bed from Aaron's and put it in my spare room. I've checked the baseboards and I don't see anything. My room has been sealed off I've moved my clothes out and washed those as well. Do you have any suggestions on what to do next? Will this new bed be safe what should I do?,please help me I'm all alone and I don't want bugs in my place and I can't move..
