Modeling sofa, how to make it look "bulged"?



I am new in modeling but not a complete noob with 3d software, I have tried to look at many tutorials but was not able to find a solution for my problem. Maybe someone can help me, I am trying to model simple sculptural sofas and chairs for my interior project but even I can somehow make the basic model, it lacks the bulged cushions - it can have round edges but otherwise or horizontal and vertical surfaces are flat, I am not sure how to make them look real. Thanx for any help.


You need additional horizontal control cuts on the back of the sofa. You can use those to model bulges.
