Know before you buy
It is very straightforward. The Level Function mechanism uses gas springs to assist the movement, allowing you to transition from a sofa to a king-size bed in one smooth, single motion.
The Charleston includes a 6-inch thick CertiPUR-certified foam mattress. While it is designed for high-quality comfort, it is best suited for guest use or occasional sleeping rather than as a primary nightly mattress.
Yes, when fully extended, the unit measures 89.75 inches in depth. You should ensure you have enough floor space in front of the sofa to accommodate the full length of the king-size sleeping surface.
The back cushions must be removed to reveal the sleeping area. Once the cushions are set aside, you simply lift the seat from the bottom to engage the mechanism.
The soft-close mechanism is integrated into the frame and requires no regular maintenance. It is designed to prevent the sleeper from slamming shut, ensuring a quiet and controlled operation every time.
The Charleston features a traditional rolled arm that blends into the back, giving it a transitional look. At 91 inches wide, it provides a generous seating area while maintaining a footprint that fits well in most living rooms.
