Biss is a single bed available in two versions: a base with storage and a base with a side opening that allows for a second bed. The first version features a storage base with a side opening (either to the right or left). The second version has a lid on one side of the base, allowing for a second bed (without a headboard). This second bed has wheels for easy removal and is available in lift-up versions (using a piston mechanism) or floor-level versions (without a mechanism). Biss features a fixed-slat bed base with adjustable firmness and removable covers in fabric, leather, or eco-leather, secured with Velcro. High, low, or asymmetrical (left and right) headboards are available.
