I suggest you look up "Memory Foam" in the "Search" feature of this forum for entries written previously by other folks. Following is my posting which talks about our mattress solution for a bed that converts to a dinette in our 13' Scamp
. You can cut memory foam with a serrated knife. A long bread knife works well. If you or someone you know has basic sewing skills, this project is totally doable. If not, perhaps the people who do alterations at the cleaners would do the sewing for you. You can also look up this project on the Internet.
"We had the same concerns for our 2011 13' Scamp
. The seating cushions turned out to be so uncomfortable (like sleeping on a table) we finally splurged and purchased a 2" memory foam topper from Target for about $30. I cut the foam to the exact size of the bed then cut it into two long strips each 22 1/2" wide by 76" long. One cushion is a rectangle and the other has two curves to match the inside of the Scamp
. I covered each memory foam piece with 100% cotton knit (think T-shirt soft) as if it were a cushion, with a zipper on the end. Now we have the softest, cushiest, mattress pad! We sleep right on the pad and on top of us we place one or more comforters depending on the temperature. In warmer weather we sleep between
the two comforters; one on top and one on the bottom. This method eliminates the need for sheets. We wash the mattress cover and comforters (as needed) after each trip.
As for storage; each 1/2 mattress cover rolls into a cylinder about 22 1/2" wide by 10" high (each one is about the size of one sleeping bag). We secure the roll with luggage straps and store the rolls under the dinette bench (see photo). The bigger question is where to store the comforters! I have several solutions. #1) For when I leave the bed set up for the day. (see photo) Fold the comforter in half (mine are about 90" wide by 76" long) so they are 45" wide by 76" long. When folded this way they fit flat on top of the bed when it is set up and looks like a neatly made-up bed. #2) Fold the comforter in half and place over the dinette cushions (no photo). Put one comforter over each dinette chair and tuck in over the top, at the seat back and over the cushion front. This way the comforters add a decorative touch to the seats without requiring more storage space. #3 More recently, I roll the comforters over a cylinder (ask for an empty fabric roll from a fabric store) a little over 45" wide (2-3" diameter) and secure the roll with luggage straps (see photo). I place the roll resting between the dinette chairs spanning the leg space under the table (no photo). This way the comforters are out of the way and ready to use at a moment's notice without using precious cargo space!
I'd also like to share another bedding tip (see photos). You can see in my photos that I have two medium-weight comforters with two different designs. Depending on my decorating mood I put one or the other design on top. A big issue for my husband and me is the shifting of covers in the night. We each have different preferences for covers AND the covers tend to shift and fall
off during the night. We ruled out sleeping bags or zippers connecting the comforters as being too confining and hot. The solution we came up with is to connect the comforters with loop and button connectors. It is easy for me to unbutton one comforter layer while my husband sleeps blissfully
with two comforters!"
