Lumpy fold out sleep sofa, dinette - how to make it comfortable to sleep on?

I'd written a long post with many questions previously and it was suggested to break it up into many individual posts. I'll start doing that here. I've decided to target mid-2000's era Winnebago Vectra / Itasca Horizon 40KD coach with a Cummins 400HP engine for purchase. All questions are related to that model.

I have it narrowed down to two individual units. I'll probably pull the trigger on one or the other after the holidays.

The 40KD floor plan that we prefer does not have a fold out sofa bed - instead it kind of jacknifes open and uses the cushions, etc to form a bed. I'm not exactly sure what the is called, but I'm sure you experienced guys know what I'm talking about.

I'm thinking that I will have to carry some sort of fairly dense foam pad cut to fit seamlessly to lay over the top of both the sofa and dinette booths and tables when they are used as sleeping beds. For you guys and ladies facing the same issue, what do you use? What are you using for sheets, as both these arrangements are not any type of standard size.

Go on eBay and search memory foam mattress toppers. They come in many thicknesses and densities. We put a 4 inch medium on the MBR mattress and it feels like a dream.

For a fold out or dinette, I'd go with a 2 inch, which rolls up tightly for storage. You may also be able to squeeze it under your MBR bed.

For the sofa, you MAY be able to leave it on when folded up as the creases pop out when opened.

Either memory foam or a blow up mattress will help.

I cut few lengths of thin wood baseboard trim and wire tied underneath the springs for a more even support..... Made a world of difference......

Adding better quality foam helped.

We use a Blow up mattress. Ours was a full size. You can get them with the electric blower to air them up-and-down pretty quickly.

X2 on a mattress topper. My setup includes an air mattress but I still have a topper for it to minimize the thermal feedback of a vinyl surface. The topper stuffs into the same space beneath/behind the couch where the air mattress goes.


There is some merit to the idea of not making the extra sleeping capacity of your coach too comfortable. You run the risk of having guests want extend or repeat their stay!

We have a queen inflatable bed we lay on top of the dinette segments to make a nice smooth sleeping surface.

We used a 3" foam topper. There was room to store the topper in the base of the sofa.
