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.
The DXRacer Craft gets a lot of things right: the seat is wide, deep, and comfortable, while the height range is versatile, and the head pillow is excellent.
