A sofa cum bed is considered more comfortable than a sofa set. On factors of frame and fillings for both quality and affordability, the sofa cum bed matches your preferences. The soft bed fillings comprise foam, fiber, and plump feathers. All these materials contribute to smart looking furniture with softness and support. However, they are firmer than sofa designs and therefore it is a great idea to pick some softer cushion types. These cushions can come in fiber seat cushions and feather back cushions.
