Hi Phoenix,
We are considering constructing a 100 natural Dunlop DIY mattress and we are seriously considering buying the latex slabs from sleeponlatex. Karl has the best prices I have found on 100% natural Dunlop and he even offered to give us a 5% MU discount which was very generous.
But Karl will not disclose to us what brand of Dunlop he carries. From some threads in MU it looks like he carries Dunlop from Latexco. From his website he claims his Dunlop is eco institute tested (not Oeko tec certified). Is the latex from Latexco the same quality as the other molded Dunlop brands (ex. Latex green, Arpico, etc)? Is eco institute equivalent to Oeko tec certification)?
Thanks so much for all your help and great website!
