Venturing through a gauntlet of sleep solutions, from mattresses to pillows to sleep tech, Mark has pioneered unique data-driven methods for the ultimate sleep product review.


  • I've personally tested over fifty different mattresses -- and I sleep on one every night (the DreamCloud, if you're curious).
  • I also review music, movies, and TV shows for the renowned Asian American publication, the International Examiner.


I've tested a wide range of sleep products, from expensive (and floppy) latex mattresses to Oura rings to buckwheat pillows. I also developed novel testing methods to gather all sorts of data on mattresses to better inform the resulting mattress reviews. Oh, yeah, and I used to host the Sleep Foundation YouTube channel. Those videos are still up, but you're going to have to find them yourself.
