After trying out the DXRacer Martian Series Gaming Chair for an extended period of time, I can say it undoubtedly has all of those bells, whistles, and more.

DXRacer Martian's backrest adjustments are fully electric like modern car seats. And it's pretty damn awesome. With the ability to find absolutely perfect recline and lumbar positions via electric adjustment, it's hard to see any downsides to such a magnificent feature.
