Hi LynnGA,
No problem at all. When you use an ampersand in a search it cuts of anything after the ampersand. If you do a forum search on Loom Leaf (you can just click the link) then all the forum posts that include both words will show up.
I would make sure that you know the density of all the foam layers in the Evosleep mattress you are looking at as well (see this article) to make sure there aren’t any lower quality/density materials or weak links in it either.
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses.
