I have performed mattress surgery thanks to this site a couple years ago. I'm been waking up a little sore over the last couple weeks and fell like its time for something new. My old set up was an queen innerspring with all original foam removed and 2 inches of latex on top of that. Latex was from FBM. 

 

I am thinking about getting simple PU base to put the latex on top of. Maybe some memory foam under the latex as well since it is at such a good price point at FBM. Little background. 5'10" , 155. I toss and turn all night. Always have so not sure it is the bed. Would love to wake up completely refreshed one morning. 

What is the absolute minimum amount of PU one should have as there base. How many inches before you bottom out so to speak. At first I was just going to get 3" of lux and 3" of hd36. The regular would be fine for me. I don't intent to get much more than 5 years out of this. I'm look at this as more of a cheap experiment. If i find the magic combination I could always buy the better materials when these go bad. A couple years ago people were just buying 5" of either LUX or HD36, then adding more to that. Has anyone laid on 2 or 3 inchs of LUX by itself? Does it bottom out? Is HD36 much softer. I read a post of a guy who put 1" of LUX above his springs and below of 3"s of MF and it made the bed much firmer. Makes me this this LUX is pretty firm, even 1 inch of it. 

I do know if I fold my latex over so that it is 4"s high on the floor it bottoms out. 

So what is the mnimum base one can go with bottoming out? Then from there I can add to my comfort layers to find the best fit. 

For example

5 or 6 " LUX

5 or 6" HD36

3" LUX + 3"HD36 

2"LUX +2"HD36

2" LUX + 2" HD36 +2 " supersoft PU

I understand that comfort is a hugely personal thing and what is comfortable to one is not to another. So if anyone has these PU bases if they could give me an idea of what they got and if they like them or if they would have change their order. 

Also what everyones opinion of 3 1" pieces vs 1 3" piece. Will they have the same compression and feel. I have had 3 1" pieces of latex in the past and always felt 1 3" piece would feel more solid. 

 

thanks in advance for any help/info

I really like the idea of the DIY mattress. I'm sure this happens to everyone though, the more you read, the more questions you have, the more unsure you become. I guess all you can do is try. And if you waste some money in the end it will probably be less money that it would cost for a store bought mattress that will not feel as good. 

I'm going to still try the 4 or 5 inch piece of PU HD36 foam with 3 inches of 32 ILD latex on top. I'm believe you are correct that it will be too firm but I'll give it a try for a week or two. If it does not work I'm going to give memory foam another try. I had a 2" piece about 5 years ago. It was junk from Bed Bath and Beyond. A 2 or 3 inch piece of 5 LB memory foam sounds good. I can then tweek it with the latex I have or just remove the latex and try the memory foam ontop of the PU foam. 

Do you think I'll notice any difference between 4 inches of PU hd36 foam and 5"s of HD36? This has nothing to do with cost, only a couple dollars,  I just don't want my mattress too high. Especially if I add some memory foam/latex at a later time.

On a platform bed (essentially a board) or the floor I wouldn't think you could tell a difference between 4 inches and 5 inches of PU base.  I've noticed that mattress protector manufacturers all tend to be optimistic about how big a mattress they will fit so it's wise to be mindful of your overall height.

Finally order and recieved my PU foam from FBM. This is just a little info for those interested in PU foam as a cheaper option and FBM. 

I placed my order on Nov 17th and recieved it Fed EX on Nov 23. Not a bad turn around time. Box was pretty beat up but product inside was wrapped and not damaged. Seems everyone gets beat up boxes from FBM. My order was for a twin 39*75 inch peice of HD36-R PU foam. On foambymail.com, it was $73 so I ordered something for 2 dollars to make the total $75 and get free shipping. If anyone was interested in the HD36-HQ I would suggest they order from foamdistributing.com. Same site but different prices. FBM has free shipping for 75 and over, foamdistributing has it for $100 and over.  I'm glad I got the HD36 over the LUX but maybe I should of got the HQ instead of the R for only 25 dollars more. Only time will tell with that. 

The PU foam stinks. I recived samples a week and a half ago from FBM. They smelled aweful as well. However they do not have an odor to them now. Maybe a very slight odor but nothing compared to just opening it. It needs time to air out. The piece of foam is clean. It is exactly 5"s high and 39"s accross. It is however 2"s short at 73"s. I will call to complain as see what FBM says. I'm 5'10" and 75"s is barely long enough. 

The 5 inchs has no chance of bottoming out. At 155 pounds it feels like a barely sink into it. I'm glad I did not get the LUX as this is hard enough just as SLAD said. I cant imagine LUX having any give. Especially at 5 inches. I could of easily bought 4 inches but it would of cost the same without the free shipping. Not sure if I could of gotten away with 3 inches of PU foam. 

PU foam feels nothing like latex. I sought of knew this but now that I have them next to each other they are very different. As people have metioned latex has give and bounce and some softness the foam does not. This is a temporary situation and I will definitly either use my queen springs or get a latex core when I move to my new apt. I should really sleep in this first before I make that statement but its just a feeling I have from just looking at the material. 

I'm interested to see how it sleeps. I'll update this after a week or two.

Foam must of need more time to expand. It is 75 inches long. FBM did a very good job with the foam and delivery. This is the second time I ordered from them and am very happy with their service. 

SleeplikeADog was correct. Even with the HD36-R and 3 inches of medium latex the bed is firm. Hopefully I will sleep well on it.
