Sovesofa

A sovesofa, commonly referred to in English as a sofa bed, is a piece of furniture designed to function as both seating and sleeping accommodation. It features a sofa frame with an integrated or accompanying mattress that can be transformed from a seating surface into a bed. Sovesofa are widely used in small living spaces, such as studios, guest rooms, or home offices, where an additional bed is needed without dedicating a separate room.

There are several common mechanisms. The most familiar are pull-out or roll-out sleeper sofas, where a mattress and frame slide out from beneath the sofa cushions. Another type is the fold-out or click-clack sofa bed, in which the backrest folds down to create a flat sleeping surface; some models use a separate foldable mattress stored inside. In some markets, futon-style configurations are also sold as sofa beds, combining a futon-style mattress with a simple frame. Mattress thickness and construction vary by model, with examples ranging from thinner foam cores to thicker combinations of foam and springs, influencing comfort and durability.

Materials and durability vary accordingly. Frames are typically made of wood or metal, and upholstery options range from fabric to leather. Mattress options include foam, latex, and spring-based cores. When selecting a sovesofa, considerations include sleeping comfort, frame strength, weight capacity, ease of conversion, and the available space for unfolding or extending the bed.

Historically, convertible furniture combining seating and sleeping functions has existed since the 18th or 19th century in Europe, with modern sofa beds becoming widespread in the 20th century. Today, they remain a common solution for space-saving living and guest accommodations.
