Some come with washable covers, which helps keep your sofa fresh. Others, like the Milliard mattress, combine softness with firm support. For added durability, support boards such as the Meliusly Sleeper Sofa Support Board reinforce the frame beneath the mattress. Choosing the right mattress depends on size, comfort, and how often you use the sleeper sofa. This guide covers top options to help you rest better.
