Hi Nate

I would stick with the 4" foam due to the possible problems with the
distance between the seat hinges while opening the seat to access the
storage below. To get a more comfortable mattress, try a layer of "egg
crate" foam or better yet a layer of real latex foam. It's expensive,
but will last a long long time. Be especially careful of the density of
any foam you buy. Foam comes in many different densities and there is a
huge difference in the way it feels and functions. The problem I had
was getting a soft enough mattress, but a firm enough seat. All of the
foam should be the same density. I made the mistake of getting a softer
rear pad and now there is a weird transition between the 2 densities.
Test the new foam by sitting and lying on it.
That's my take on it anyway.
