Hi DaveD,
Sleep Science is a company I wanted to like. The density of the memory foam and the quality of most of their materials seemed good (at least in some of their mattresses but not all of them because some use lower quality/density memory foam) and the only real issue I had was not knowing whether their foams were certified for harmful substances and VOS’s … so some time ago I phoned them to find out and talked to someone in production. They were particularly unhelpful and on the edge of rude. Their answer to my questions were along the lines of “we use the same chemicals as everyone else from Dow, Shell, and BASF and they are tested in China”. When I asked about who tested them or whether the testing results were available or why they weren’t being tested by CertiPur or Oeko-Tex … he ended up saying he would call me back and was busy (he didn’t even have my number) and hung up. Clearly they aren’t interested in being transparent about their foams other than the fact that they are pouring them. I wasn’t at all impressed.
So in the end … they may look good “on paper” but they are an unknown and untested foam from my perspective since what is being tested for and who is doing the testing is completely unknown. There are several Chinese foam pourers who are CertiPur certified (Sinomax and Zinus and Health Care Foam are examples) so they could easily certify their foams as well.
There is also more about mattresses that use foams that are sourced in China in post #6 here and post #2 here.
The good news is that they are available from an store with a great return policy so testing the mattress and seeing how it affects you and how suitable it is for your needs is a no risk proposition at least financially. This may be worth considering if there are no better alternatives or independent manufacturers near you where you could get similar value with more transparency and actually test the mattress before buying it but overall I would tend to avoid them until they have certified their foam.
