There are several types of sofa beds to choose from: Pull-out Sofa Beds: These have a fold-out mattress stored beneath the seating cushions, which can be easily pulled out when needed. Futon Sofa Beds: Futons consist of a mattress that folds down to convert into a bed. They are versatile and often have a minimalist design. Click-Clack Sofa Beds: Click-Clack sofas have a backrest that can be adjusted to different positions, allowing them to transform into a bed. Daybeds: Daybeds function as sofas during the day and can be used as a bed by simply adding bedding. Sectional Sofa Beds: These are larger sofas that have a built-in pull-out bed or a hidden sleeper section.
