The Luna Corner Sectional has a couple of options which might fit these parameters.
Option 1 is available as a 4seat/2seat with an ottoman in front of the corner seat on the 4 seat side, and a bumper seat on the end of the 2 seat side, thereby creating the 3rd seat, but it has no back.
Option 2 is the 3 seat/5seat version, and the 5th seat is a chaise.
Please contact the sales office at 888-467-6278 for further information on these specific configurations.
