Mattress Forum

Through it all, one thing has consistently worked for her. The living room sofa. A modern-looking Galerkin piece with a single cushion that spans its full width.  Every time she sleeps on it she wakes up without back pain.  In fact, that's what prompted us to try a latex mattress, because we thought the latex foam would most closely resemble the feel of the sofa. But so far it doesn't seem to be working out that way.

 

Maybe we can still come up with the right combination of latex layers for the Flobed but we've already tried numerous combinations, with and without the convoluted layer, with no luck. Is there any way to scientifically measure the firmness level of our sofa cushion so we can try to match it up with a specific ILD level of latex?

 

Or...maybe we should just head on down to the one of the bulk foam stores in town with our sofa cushion, pick up a 6-inch thick piece of polyurethane furniture foam that matches it as closely as possible, throw it on top of a box spring and call it a night.  I know everyone here is negative on PU foam but if that's what works then that's all that matters.  And it's a lot cheaper than latex too.

 

My biggest questions are, why would the sofa work so much better for back pain than any mattresses?  And is there any way I can accurately measure the firmness of that sofa cushion in terms of ILD, to match it up with some latex or PU foam of the same firmness level for the mattress?
