I bought something similar from an indie mattress maker off Amazon a couple of years ago. The construction sounds nearly the same, so I wouldn't be surprised if it was from the same source factory.<p>The quality has been surprisingly good, for a mail-order latex mattress, and a King was actually maybe a little less than what was outlined in the article--want to say it was around $800.<p>I will say that it hasn't fully held its consistent shape over the couple of years I've had it, though, and has some peaks and valleys--nothing terrible, but they're there. I generally expect 5 years or so from a mattress, so it's a little ahead of schedule.<p>I have no way to compare to a "brand" mattress of similar construction, but there may be at least a little "get what you pay for" going on.<p>Still, good to see disruption over the showroom model, if nothing else. And it was certainly neat to pop the shrinkwrap on it and see it expand!
