We had Knox Foam make us a custom mattress for our teardrop a few years ago, and I'd like to find a similar product and service to get better foam for our Casita
cushions. Unfortunately Knox seems to have gone out of business. We use the existing cushions for our mattress (haven't given in to the full time bed idea yet) and want something a little more firm. There are lots of custom foam mattress companies on the internet to choose from. Any suggestions? We're not looking for things to put on top of our cushions, but new foam to replace the stock material.
