uncomfortable travel trailer couch

I wanted to post a picture, but am not able to, anyway...as I said in my original post...the couch is one piece sewn together....the bottom cushions are not removable, they are sewn together....no zippers..the back cushions are sewn together as well....the entire couch is sewn together, can not remove cushions or lift them up to insert anything under them...they are NOT removable....so with that said....can only take them apart and resew....but wouldn't dare do that. slip covers can not be applied....all one piece...google forest river flagstaff 25ks and click on image icon under google search bar....that will take you to pics of the couch that sits in front of the murphy bed....looks like a normal couch, jack knife couch....BUT....cushions can not be removed....ALL SEWN TOGETHER AS ONE PIECE....so thanks all for the solutions...but the only thing I can do is maybe place a foam piece on top of the seat cushions and go from there. Would love to have recliners or swivel chairs but that will not work either as they have to be able to recline FLAT for wall bed to lay over them and there is storage for the trailer underneath...so they would be in a hole ...reason for jack knife couch. Hope this clears it all up...and THANKS TO ALL AGAIN, appreciate the suggestions and assistance. :)
