We bought this sofa after extensive research online.  We had to have a sofa that would fit in the rear of our 5th wheel living room that would give us the pull out bed and yet still fit behind the double slides on the RV, which required a sofa that could pinch into a 39.5" width area.  This one fit perfect, not to mention an incredible look and a solid seating area.  No fluffing down into this sofa.  In addition to the width we also wanted a long sofa.  The area in the back of the RV could take up to 94" and we didn't want large gaps on the sides.  At 86", again it was a perfect fit leaving only 4"  on each end.  Then, to top everything off it comes unassembled ((Two main pieces and hardware and small pieces)if it were assembled it would not have fit through the door.))  Assembling it in the RV was easy and fast.  We could not have found a better looking better fitting sofa if we had tried.  Thanks Wayfair!
