I know the memory foam is probably tempting but I would tend to stay away from it in your case simply because it has little resilience and will not help in any way with support even though it may with pressure. You are one of those "difficult" cases that has issues with both pressure and support and this is compounded with the weight. The memory foam would add softness but I I really think it's risky in your case because you have both pressure and alignment issues and the only materials that have qualities that can help with both are latex or HR poly.

The costco topper is the same ILD throughout and I believe that in your case your upper body needs something softer than your hips. The only reason I would consider the latex from Costco at this point is because you can return it ... and because you never know whether your actual experience would be different from what you might otherwise expect.

I called Costco to find out the ILD for my own information as well and they didn't know so are checking with the manufacturer and will call me back in a day or two. They did tell me that the "manufacturer" was Literielaurier (they thought they actually made the latex which of course they don't) so I called them to find out if they sell toppers to the general public and they do! The person who would know more about prices and options was busy with a customer so I left a message on his voicemail and he'll call me back. I'll post here when I get more information.

I'll wait to hear the details you'll get from the latex from Costco before going there. Too bad the 2' model is only available in twin and double.

In any case he told me that the Costco topper was 40 ILD which would probably be too firm for you. It comes from LI.

He also told me that the Quebecois also like their latex either really soft or really firm so the toppers they sell from stock are 19, 40, and 44. When I told him that the people here would likely want a greater range as there are many who build their own mattresses, he said he could get it in other ILD's as well. They do a lot of latex volume and have a good relationship with LI. He will email me tomorrow with the prices for queen in 2" and 3" so we can get an idea of how they do price wise. They will also cover it for an extra cost.

It wouldn't surprise me if your quilt was giving you as much or more "support" than memory foam just from surface tension (depending on what it is and how it lays) but every inch of "lost support" would add up in your case. An inch of memory foam and an inch of soft poly could cause too much sinking in for your back to like it even if the rest was latex. Latex in the softer ILD's will usually relieve pressure (almost) as well as memory foam. I would also really make sure that you know the ILD of what you are buying as there is such a range that the wrong ILD, especially in a thicker layer, could really aggravate the problem.

That old quilt is really worn out, a bit uneven and not tight at all. I only use it because it softens up the surface a little. I tried it without and the bed is a little harder. I put it over top of the mattress pad, which is holding the egg crate and the latex together, so it doesn't move. The pad does however tightens things up and the surface is not cushy at all, just a tightly stiched cotton. I know I need support but I'm certain that some of the pain I have (lower back and hips) comes from pressure, hence my hurry to find a fix. Even ordering today would give at least a full two weeks before delivery. Today, I had to hold myself not to rush to Walmart and get the cheap 1.5 inches Simmons (*LOL*) memory foam pad...

In other words the core can "help" the upper layers distribute downwards pressure and improve comfort and the upper layers can "help" the core to target upwards pressure and improve support.

The "progressive" resilience qualities of either the springs or the core materials along with the ability to "target" pushback through "point" compression as opposed to "broad" compression are key parts of how different mattress constructions provide support to different sleeping styles and body weight/measurement distributions.

http://www.ikea.com/ca/en/catalog/products/70163102 which felt not too soft and somewhat supportive.

150$ for the queen size. I brought it home and will try it along with the latex (took off the quilt and egg crate foam). Should I put the latex on top or under?

"As request topper Talalay latex ILD 40

Queen topper 2 inches 189.00

Queen topper 3 inches 269.00

Queen topper 2 inches with cover Bamboo quilt with wool 249.00

Queen topper 3 inches with cover Bamboo quilt with wool 329.00"

Their prices seem very reasonable indeed (especially when you consider lower shipping, no exchange, and no cross border hassles) and they would probably be the same or similar in other ILD's and similar value in other sizes. I am impressed with their cover and pricing there as well. This is one of the few times where I've seen better value in Canada than an equivalent in the US.

As far as latex on top or under the poly I'm not sure as I would need to know the ILD, density, and quality (HR, HD, or something else) of the poly and the "real" ILD of your latex to give a more "thought out" suggestion. I would "probably" try the poly under the latex first though and give it a couple of days before you switch.

Just made the bed and I set it up with the poly under. Still feels firm but a tad softer than before. Strangely enough, even though the latex foam feels softer than the poly, it seems to give more "pushback". If my arm goes numb again, I'll switch and see. I could also try the poly along with the egg crate. Hours and hours of fun....

2.2 lb foam, this should last how long?

If it really is 2.2 HR poly and made by a good manufacturer ... it should last you a long time ... meaning years. It would last longer under something else than it would on top of the mattress.

The only thing missing in the description (unless I missed it) is the ILD. This in combination with not knowing the ILD of your latex (which from foambymail is always unknown) makes it a little difficult to "theoretically predict" what layering would be best so we'll just have to go with your personal experience here. Typically though the HR denser poly that you more commonly find has a higher ILD although it is available in much softer ILD's as well ... it's just a little harder to find.

The next option I would try after a couple of nights on this one and depending on your "sleep all night" or at least your "sleep part of the night" experience would be the eggcrate over these two layers.
