We have a full-size futon mattress that is a bit soft and lumpy but otherwise in good condition. It has a green canvas cover that needs to be washed (machine washable) or could be replaced. We used it as a sofa rather than a bed, and now it's a bit too soft for that purpose. I thought I would see if any one wants this before putting it in the bulk recycling. It might make a decent mat for kids to play on. If interested, please email me directly at sfussell@andrew.cmu.edu. Sue
