6 or 10 inch Gel or Memory Foam?

[usmc70_14]

Hello everyone..

I am in the planning stages of the interior of my 7x12 vnose trailer that I will be ordering this month.

I'm my build I am looking to do an office/entertainment area in the v nose portion of the trailer. Now in the back I would prefer to make some type of bench that converts to a queen bed. I am wondering what you guys are using for bedding ie Gel, memory foam etc. I have a preference for firm cool material as I live in Florida. Regular memory foam seems to get warm along with that "sinking" feeling when you lay in it for a while.

What are you guys using and what would you recommend if you could do your bed /sofa all over?
