DXRacer really has made a top-of-the-line chair with the Martian. The frame is firm but comfortable, not crushing you in but letting you comfortably sit. The headrest is extremely versatile to cradle your neck no matter where you're sitting, and the powered back lets you perfectly adjust for how you want to sit.

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.
