I’m experimenting with replacing the top layer of foam (soft density) with a 1" firm latex mattress topper.
The bottom layer of GFC foam is very hard density to prevent bottoming out, coupled with a very soft top layer for ‘comfort’.
I have a 3" medium/firm latex topper that I’ve used for 7 years down in the camper shell (lower bunk) that has been very comfortable for me as a side sleeper and wanted to reproduce that experience with the upper bunk (what I call the GFC sleeping area) without adding any extra height or replacing with an inflatable mattress.
Haven’t tested it out other than comparing the two side-by-side (the OEM GFC mattress in one cube and my half foam/half latex in the other) on the floor so can’t comment yet on what the full experience will be like, but I can already tell it’s slightly softer without bottoming out (my concern with replacing the whole GFC mattress with a 2" latex topper.
Presenting another option for how to make the GFC mattress more comfortable.
Also, FWIW, I’ve slept about 10 nights in the GFC with the standard mattress and while I thought it would be too hard for me, I slept extremely well on it - so perhaps I’m trying to fix something that isn’t broken.
I also opted not to add the latex topper under the GFC sheets (but on top of the standard mattress) because I wanted to keep the height stock so that I could keep my bedding (large down duvet) up top and still close it with ease. I just toss the pillows in the bed and use those for daytime napping while on the road.
