Sofabed by Muji, dark grey, opens to double bed (Naphill HP14)

Metal frame with wood slats. Still in good working order as it is a simple open build. Mad up of four cushion pieces - main large seating cushion that opens to form the mattress and folds over to form the seat, a back filler piece and two back rests. Two slats are fixed following a break but I have used it for years after since the break. No fire safety label.
