Walmart offers the DHP Delaney Sofa Sleeper in Black or Brown for $199. Opt for in-store pickup to dodge the $37.74 shipping charge. That's the lowest price we could find by $92, although we saw it for $21 less last September. It converts to a full size bed and features a 7" foam mattress. It measures 16" x 43" x 73" when converted to a bed.
