JackKnife couch replacement

Ok I decided to change out my Jack Knife Couch. I ordered a 62 inch double recliner and removed JK couch and OOPs. The push out floor must remain due to the all the internals that control the push out are housed in this large step. So the recliners must be mounted 6 in above the main floor on this box. It looks funny and you feet hang in mid air.
So I am back to square one,. Has anyone run into this issue? Both my Dinette and Jackknife couch are up 6in. I need a couch that almost bolts at the bottom of the seat
