We bought a 3" Serta Rest memory foam topper, it is egg crate, and was a little less expensive then the Serta Memory topper, also 3". The more expensive may not have been egg crate, but solid. Unboxed it today in the RV, to air out a bit. Feels like 3" of dough. ;-) It's gotta help with the plywood like mattress we have in the RV.
