I sleep on a futon, it helps my back...but how can I make it more comfortable?

Question:I keep it up, because I need the support, but I just want to make it more comfortable?! Any suggestions?!

Answers:
you could put a better quality futon mattress on it, but the cheapest way is to go to wal-marts and buy a egg shell (its a piece of foam with ridges on it) put on mattress and then put futon cover back on. no one will know its there but you and it is comfortable, i have one on every bed in the house. trust me you will love it.
