well here it is ! three talalay toppers plus a 3" piece of HD foam, with snugfleece elite on top
the height so far is 10" now that i finally took the old mattress out from underneath i can move on to final design stages and decide which if any more layers to add, because i can now test it properly.
also the bed frame seen here is of a do-it-yourself variety but it wasn’t made by me, and i won’t be using it for the final system because it isn’t heavy duty enough.
i will give you DIYers out there this advice though - if you don’t have a son or a brother or somebody to help you - may want to stick with thinner pieces of foam ! because to add just one layer as it comes in you pretty much have to take all layers off and carry them to where you can put them on other beds then carry them back, and carrying 60 x 80 inches pieces all by yourself can get pretty tiring if they’re heavy, and especially tiring if they’re firm foam and will not roll up properly. so try not to order things like 6" king size latex core unless you have somebody to help you move it !
as the toppers came in one at a time and i had to shuffle everything over and over again i am pretty sore right now. almost makes me want to not order any more layers just so i wouldn’t have to do it all over again
