A frame that fits sofas with room for an extra bed, retractable at the bottom of the sofa. A comfortable and solidly made place for occasional sleeping. It has 17 elastic slats that hold the mattress. The distance between the slats is 6 cm. The maximum weight of a person using the frame is 90 kg. The size of the frame makes it easy to match a mattress from the VOX Furniture collection. For the frame we recommend foam mattresses for the lower bed 85x195 cm with a height of 8 or 12 cm of your choice. The frame has safeguards on the shorter sides to prevent the mattress from slipping off (the dimension of the safeguards: height 14,5 cm, width 43 cm). The height of the unfolded frame from the floor to the edge (frame) of the frame is 22 cm. Bottom mattresses with a height of 12 cm do not fit only to sofas and beds from the 2piR collection.
