Comfortable Futon Sofa (Mattress + Frame)

I just graduated Stanford and into a house, and no longer have a need for my futon (looking to buy a sofa for my living room instead).

• Durable, black metal frame construction.
• Quickly converts from sofa to a full-size bed.
• Also comes with a black futon cover, which is removable and washable.
• The futon mattress is itself very comfortable.

Must be able to pick up in Palo Alto. Looking to sell for $150 OBO.
