Since I leave my bed made all the time I decided to order the 4" Southern Mattress with 2" memory foam. I already have 2" memory foam pad that I use on top of the Casita cushions so I asked them if I sent them my memory foam, could they use it. They stated I would have to send it to them but if they could use it they would.
They called me back and said that it will work fine. Sending them my memory foam will save me $90.00! Just thought I would pass along in case someone else was thinking about ordering the mattress and already had memory foam pad.
Southern Mattress has to make sure that the quality of memory foam is good enough. I assume because they are putting there name on it and that they would have enough material to cut and use with their foam mattress.
The Southern Mattress makes the mattress out of HR-30 foam in a 4" or 5" option. They also give you the option of adding a 2" memory foam layer on top of the base foam. This is completely covered with padding and mattress fabric materials and will look just like any other mattress except will have the curves on the back side to fit the Casita.
The Southern mattress when it is complete will be 6" to 11" thick depending on options. The finished full size bed for the 17' Casita will be 74" x 52" from Southern Mattress.
They will also make twin and king size, just give them a call and they will let you ask all the questions you want. Just be ready to be drowned in southern kindness and hospitality.
If you look at the picture that Terrance posted, you will see the 5" base foam with 2" memory option.
Received my new Southern Mattress yesterday, very, very nice! I laid it on the floor and tried it out for a while. Even thou the Casita cushions with memory foam pad that I had been using were ok, I think the new mattress will be much better and easier to make the bed up and live with. I paid $360.00 after sending them my memory foam plus shipping.
Can't wait for my next camping trip to try it out!
