Mattress Forum

The foam industry - both visco and latex - has a golden rule they use to achieve goals such as yours - 3" is the magic number for thickness.  That's why with most visco matts you see at least 3" of visco on top of high density foam, and on latex they try to use 3" of talalay on top of the harsher denser dunlap latex.

3" may be more money but... you may want to ask around here for more expert advice...  (don't mean that in a bad way - most advice I have seen is very good!)

Hope this helps,

Leo3, are you using the 24ILD talalay latex from RMM?   How do you like it?

They could add 1" if the 2" is not enough.  Gunmann, have you done any research on whether 2 1" pieces would feel noticeably different than 1 2" piece?  That is an issue that has not been explored enough on this forum.  My assumption has been that there would not be much difference, but I have never tested it.

 

Sandman,

Every mattress factory I have worked in has glued latex layers together (using latex adheasive) so there is no shifting of layers.  if you use the same ILD two 1" layers feel like one 2" pad.  If you use different ILD's as long as you put the softer ILD on top you will get a mix.  If you put the firmer on top it will feel like the firm one!

I disagree.  I think 2 x 1" layers will feel slightly softer than 1 x 2" layer if they are not glued together.  Being separate, the top layer will have more opportunity for lateral displacement in response to the body weight whereas with a solid 2" piece, body weight will cause more downward displacement that I think could result in a slightly firmer feel.
 

Sandman, Yes I am using the 24ILD talalay from RMM, 2" layers and then got another 2" over 2 months ago I think.  Now it is soft and cushy.  My shoulders and hips are good now.  But if I add anything other than my trusty soft poly blanket it is no longer soft .  I do find though side sleeping my leg (right below the hipline) maybe sinking a bit much and it kinda feels like pushing back sometimes.  If I didn't have the heat factor I probably could sleep through it.  The room is 78 degrees, and yes if only the room was cool I wouldn't have this sauna of a mattress problem.  I can't turn the a/c down though.

 the top layer will have more opportunity for lateral displacement  can you please explain what that means.
 

The warm room is probably most of the problem.  There is no general agreement on ideal temperature, but most say somewhere in the 60-72 degree range.  For me, I tend to think high 60s, so your might have a room 10 degrees hotter than ideal.  That is hard to overcome.

Maybe you can get an a/c for just your bedroom.  That way you don't have to cool down the whole house.  The Chilipad might be worth a try if returnable.
