DH is currently building his male fantasy room (model railway, scaletrix (SP?), pool table and home cinema). My input is the seating for cinema bit. Want something comfy and child resistant but its an attic and quite twisty stairs so probably couldnt get huge sofas up there. Thought about modular but all I can find is either really expensive or uncomfortable looking rattan. Other thought is 3 seater futon sofa beds, does anyone have one and is it comfortable or would children bouncing on it make the mattress slide? Thanks in advance
