CONGRATS!!!!!! I use regular queen size on the bed (also have a foam mattress topper and right now a mattress pad heater. The sheets, though, fit fine
. The couch I am not sure of. We used queen on it without a problem. Our 320 RS is currently getting some warranty work done along with the pink juice for the winter. Or I would go and measure it. Hope this helps!
