A convertible furniture piece is disclosed, having a bed configuration, desk configuration, and couch configuration. The furniture includes an outer frame that houses a bed frame and desk, along with the mechanism for raising and lowering the bed frame and desk. The outer frame, bed frame, and desk are interconnected such that the bed frame and desk transition together between a bed configuration, where the desk sits directly below the bed frame, and desk configuration, where the bed frame is stored vertically, while keeping the desk level with the floor. The furniture may be converted to a couch by repositioning a foldable mattress topper as a backrest against the outer frame while the bed frame is horizontal. The furniture may further comprise a bed frame extension, allowing the foldable mattress topper to be repositioned as a second mattress alongside a first mattress.

A sofa bed with three moving seat bases that transforms between a bed configuration and a sofa configuration. The sofa bed includes supporting legs and armrest. The armrest does not extend to the floor and allows the set of rails to form a notch such that the back end of the sofa bed may be installed on a raised area. Each of the seat bases, and corresponding cushions, are located between the armrests. The seat bases are interconnected with a set of slide rails that allow the seat bases to move relative to one another. The sofa bed also includes a locking mechanism to hold the sofa bed in the sofa configuration.

A bed assembly and method of use for connecting a foldable bed frame to the back support of a sofa. The assembly includes a first slotted link attached to the back support and a double slotted link affixed to the foldable bed frame. An L-shaped adjustment link defining a plurality of apertures is slidably connected to the slotted link and pivotably connected to the double slotted link whereby folding the bed frame causes the back support to displace along the first slotted link. Depending on whether the foldable bed frame is being removed from or inserted into the storage cavity within the sofa, the displacement of the back support along the slotted link causes the space between the bed frame and the back support to change.

An attachment arrangement for attaching a structural element to a supporting element of a piece of furniture operable between multiple configurations, the attachment arrangement including a longitudinal guiding arrangement for attachment to one of the structural element or the supporting element, and an engaging arrangement for attachment to the other of the structural element or the supporting element. The engaging arrangement includes a first engagement member and a second engagement member operable to, when used in the piece of furniture, engage the longitudinal guiding arrangement to provide a translation and a rotation of the structural element in relation to the supporting element between a first configuration and a second configuration of the piece of furniture.
