Hello - I was wondering if anyone has every made their own box-springs replacement for the bed... using a torsion-box design. If so, how did it go, and did it provide a better night's rest? Just curious because I've got a nice king mattress being supported by two cheap twin box springs, and they're betting to sag a bit... leading me to wonder if they're responsible for the mattress being less than comfortable lately...
Thanks in advance, Chad
