What's the best mattress for back pain?

Hi davess,

I took the cover off today to try to align the layers better, and it turns out that they’re not lined up because they are all slightly different sizes (the upper polyfoam layer is wider than the lower layer and so hangs off both sides, etc.). Functionally this doesn’t really make much difference, but it seems strange to feel the side of the mattress and not have it be even. Is this normal?

It’s possible that one or more of the layers is either stretched or bunched and if you pick up the edge of the layers and “wave” them into position like you would a sheet (rather than pulling or pushing on the foam) then it may even out the layers.

It’s also not unusual for foam layers to have variances in their size in the range of =/- an inch but if one of them is clearly larger than the others then it’s not difficult to trim the excess off. There are some instructions for cutting foam in post #3 here and some additional posts about cutting foam with more comments and some pictures in post #19 here and post #1 here. Foam Order would also be able to trim it for you as well.
