Sofa weight?

[2ags81]

I know it's fairly common for folks to remove the stock sleeper sofa in their RV and replace with two recliners. I am considering this modification. I have a 2015 Rockwood 2618W (Windjammer). It has the sleeper sofa with air mattress. Does anyone know the approximate weight of the stock sleeper sofa with air mattress? I would like to keep the weight on the slide close to the same as with the sofa if possible. I have found small recliners that are about 85 lbs. each.
