You can also pay $70 to get both the frame and the mattress
I purchased the whole thing a year ago with $130
Price is negotiable
Really easy to convert to full size sleeper
Relatively light weight compare to most futon
Perfect for student dorm

Sturdy metal frame + Polyester mattress cover
Use as a bed or as extra seating (fit 4 people)
The only thing missing from origin package is the mattress retainer clips (but you don't need that...)
Really simple to assemble
