BL3 is a Lampolet steel-made 3-fold metal action sofa bed mechanism, fitted with a metal or wooden slatted base. Available for 185 cm long sprung or foam, single, large single and double mattresses in a choice of widths.
The two-motion opening is effortless, operated through a patented mechanism that will do the hard job. To open it you will just have to pull the frame out from below the sofa seat cushions, then unfold the base and mattress so that the legs will fold into place.
The BL3 has a history of over 30 years. It is a heavy duty mechanism designed to withstand several openings and closings, which makes it ideal for regular use, for private homes as well as contract and hospitality settings.
