Need advice on mattress for a morbidly obese person

I am reposting this as anew topic since i reeally could use some answers as soon as possible.

You know I am getting fed up with mattress makers,even the smaller ones who will sell anything to make a buck and not consider weight or anything. Its pure crap in my opinion. ESpecially high end mattress sellers who charge exhorbitent amounts North of the border.By the way I have mentioned your name ,Phoenix and one had some quite negative things to say about you .They dont like me because i ask so many questions before purchase and can be brutally honest ,but they certianly had somethings to say about you regarding your lack of knowledge. Now i find that inaccurate and rather rude since you recommend one of these matttress makers on your site. I stuck up for you because Gawd knows you do this to help people. And thank you for that. But this industry is riddled with people overcharging, trying to make a buck and many unwilling to work with people who have disabilities and need extra help. Laslty there are many decent people in the industry I am sure (I hope) …maybe i have only just met the greedy ones. who knows?Anyway I wont post what they said .And here is my repost. Thanks.

Ok Phoenix ,you are so helpful .We purchased the LATEX DREAM FROM DORIMER which is 10 inch bed.

Top is 24 ILD talalay latex 4 inches
Middle is a 3 lb poly foam but "cut " so as to have more give. AS Dorimer states.
bottom layer is 3 inches 2 lb firm foam.

Here is the result .My husband sunk thru the latex hit the mid foam and lost support -hence lower back pain.

To get by until we can get he mattress reconfigured,we put 4 in Dunlop wrapped in cotton and wool on TOP of the 4 inch latex and of course acheived some support but also too soft.That makes it a 14 inch bed .which is fine of adjustable but not for husband who is not in alignment. But close to comfort and much less mid back pain.

My question is this. Tomorrow Dorimer is willing to redo the bed and put in firmer foam .However i have deduced that will not help as much as using the 4 inch dunlop 28-32- ILD as a top layer. Am I correct ? Once the cotton and wool cover are removed form the dunlop 4 inch "topper " it will become a bit softer correct?

we are trying to achieve a medium or medium firm bed .As we can always make a firm bed softer but not a soft bed firmer.

he is a side sleeper.

here is my idea and please ,anyone give me a comment.

if We use the dunlop latex ,our own ,it voids my warranty --i dont care about that.

There is no way that 24 ILD talalaly alone will offer any support for my 305 lb husband. so I am asking this ?
we firm up the middle foam ,leave the boottom 3 inches as is. Use 30 3lb hd foam for middle of bed. Then have dorimer glue the dunlop 4 inch 28-32 ild latex on top .
Take the 24 ild latex ,and use it as a topper if the bed is too firm. I also have a two inch 18ILD latex for comfort if the 24 ILD tallay is too much. . I think 4 inches of comfort on top is too much latex so ask them to make it a 3 inch topper.? Does any of make sense?

so the latex dream is good for someone 200lbs and under but doesnt work for an obese (midsection heavy ) person like hubby305 lbs

we only get one shot at this using our own dunlop latex,and I read the tutorial on the site.

My only concerns are the poly foam
1- is it necessary to firm up the support layers if using the very suportive dunlop?
It is amazing he support it gives on top of 4 inches of 24 ILD latex ,that is 8 inches of latex and the support mostly comes from the dunlop .It is my understanding that these layers should be reversed. Dunlop on bottom and 24 ILd talaly on top if necessary
2- I am guessing it is necesary to firm up the middle foam layer ? to a non cut 3lb foam which still has some give for support ?This is a 30lb weight I believe ? 60 is very high and very firm ,not suitable correct?
3- The bottom 3 inches is a blue 2 lb foam ,quite firm ? not certian whether we need this firmed up or not ?
4-lastly these poly foam layers must hold up a heavier dunlop latex and a heavy 300lb hubby To create a medum to medium firm bed. So my questions are mostly about the poly foam and yes I have read the thing on poly foam.These are higher quality foams dorimer is using and should suffice.
5-last concern is in using the dunlop in place of the talalay AND FIRMING UP THE FOAM will possible create a too firm bed?

I realize that this is an experiment .And there is no going back but the talaly wont hold my hubby so it is wise to use our dunlop correct? So even if the foam were firmer ,the bed is useless to him even with firmer foams on bottom as he will go right thru the comfort talaly layer. The actual bed hte latex dream is very soft foam on bottom and bends wellon the adjustable but no suport for hubby .

if the bed comes out as too firm we can try toppers Right?

is it my understanding that latex takes on its firmness from what is underneath it? so firm foam will make the latex firmer?

Our last option is to leave the foam as is ,and not use firmer foam,remove the talaly and replace it with our dunlop .which is much firmer?

we have tried this a few years ago —
dunlop latex on an extremely firm spring bed–no go too firm. So the foam underneath it has to have some give . But as you have stated the poly is a support layer and cannot be too soft. Someone mentioned 60 foam for heavy people . I think that is to firm correct? just use 30 wihtout cuts in it (please dont ask me to explain the cuts) it makes a 30 foam softer but still holds weight.

all of this on an adjustable bed .Now the present configuation actually moves on the adjustable --that is 6 in poly and 4 in tallaly 24 ild and 4 in 28-32 ild latex . IT STILL MOVES .

Bottom line --must use our own dunlop as the talaly is too soft .
But does the support foam need to be firmer?
It would be madness to firm the poly and use the talalay as he would just sink thru .Correct?

Now we kept our tempurpedic ,so if this doesnt work just go back to it.begin agian .

although My hubby has improved stiffnes of his arthritis with the latex and is able to get out of bed just fine. HIs arthritis is MUCH improved with the latex and moving at night.However mid back pain was only improved when we added the dunlop on top of the latex dream bed.This says that the configuarion of the latex dream is too soft for heavy hubby. We would rather not return to the tempur .

So important we get this close to right .Can you help please asap ? we are taking bed to dorimer tomorow .

It is good to find a bed maker willing to work with us but once they use a customer’s material it voids the warranty .I am ok with that becasue the bed ,as is,is useless to hubby .

I wish I knew more about foams and also dunlop and how dunlop responds 1- when not wrapped in cotton and wool ?2- how dunlop reacts when paired with a firmer foam ?

The reason I ask this is that a 28-32 dunlop made in indonesia is actually a support for a bed, but for a heavier person it could be the top right?

There are a lot of variables here . Its ok we may not get it just right but anyhting is better than too soft.I should add that dorimer will replace the mid Poly foam with a firmer foam and keep the warranty .But am I right ? that wont help as hubby went right thru the tallalay to the foam undeath and that did not support him.
I am guessing we need To firm up the mid poly foam anyway .Adding the dunlop will only help with support. And a topper will help with pressure relief if necessary ?

I really hope this makes sense. And you can give general advice on how we can build this bed tomorrow morning ? uggh sorry about thislate date . but we cannot keep bed as is and no real return but can redesign .

please advise and thnak you so mch in advance.
