I am creating a sleeping set-up for the back of a 2011 Toyota Rav4. I have calculated that I can fit a double bed if I design the platform correctly. While most car campers use a very thin mattress, I am opting to go thicker with a 6 inch, as I believe that will be a good balance between comfort, support, and preserving head room. I am a 6-1, 200 lbs, fairly lean with broad shoudlers, and prefer a medium-firm bed. I’m a side sleeper but I sleep at a bit of an angle with my shoulder kind of rolled forward tucked under my chin. With these things in mind, what are your thoughts on this configuration?:
-base layer: 4 inch of HD-36 HQ Foam (35 ILD) from Foam Factory
-comfort layer: 2 inch soft Dunlop topper (20 ILD) from SleepOnLatex
The bed will be on a flat piece of 3/4 plywood. Thanks for your thoughts!
