foam density

[phoenix]

Hi alasearwax,

(got your name right this time!)

I am replacing the foam in a daybed that also is used as a sofa, am buying the foam from foam factory. I am a bit confused what foam would work best…I would like it comfortable for sleep but it will be used more as a couch. I am not sure what my old foam stats are, I would like it to be of medium firmness, do not want to sink in deep or have it hard with no give.

You may find these two articles from the Polyurethane Foam Association (PFA) useful. Specifically, section 4.2.2 about IFDs in this article, and this article about polyfoam density. There is some discussion there about common IFDs for different cushions and sleep surfaces.

If you are considering Foam Factory (aka Foambymail or FBM and other names as well) you may wish to read this post and this post and this topic (about their polyfoam and sources) and this post (presumably from a past employee)for some commentary and information about them, and sources of their foam products.

Also, if your daybed is using a polydeck or link spring unit, you may wish to reinforce it with a plywood deck or a binkie board, or something similar, as some of those units can allow for quite a bit of sag.
