Home / Antique French Beds / VINTAGE OAK FRENCH KING SIZE BED - g56 VINTAGE OAK FRENCH KING SIZE BED - g56 £195.00 Information Oak French King Size Bed. The size of this bed is 150cm wide x 210cm long inside the frame. There are old replacement fixings to the side rails. The bed has slight movement when together. However it was in every day use before we bought it so may be ok when the base is added.
