I didn't know I need a gaming chair with a wiggly backrest but now I've tried it, it makes so much sense

I can't be the only person who shifts around in their gaming chair and ignores all ergonomic advice, right? For me gaming chair backrests have never quite hit the mark because I lean and I move—I'm just generally an awkward sitter, apparently. Even the most expensive gaming chairs I've tested seem to be missing something in the backrest department, especially now I've had a chance to sit in ThunderX3's all new Core range of gaming chairs at Computex today.

Seriously, this thing has me questioning why adaptive backrests aren't already the standard for gaming chairs.

As it goes, it took about 50 years from the invention of the can for the can opener to be invented. Similarly, it's taken ThunderX3 50 years to invent the adaptive backrest, since NASA first observed Skylab astronauts and discovered neutral posture so the first ergonomic office chair could exist.

To be clear when I say adaptive backrest, I don't mean adjustable. There's no knob to push the lumbar support into your spine. Nor is there a separate cushion with adjustable straps; frankly these just don't do it for me anyway, and I'm sure I'm not alone in the fact I usually end up using them as the headrest instead. The company has dubbed it Lumbar 360, though it doesn't have 360 degrees of motion. It's more like thirty in each direction.

Instead of the many (now totally inferior) alternatives, the Core-Loft backrest actually moves around with you as you shift in your chair. Now I didn't realise this was something I needed, but now I'm feeling like all the static, and even adjustable backrests, I've tested are really pale in comparison.

I must say the chair itself isn't the most attractive thing I've ever sat in, though. The wings on either side of the headrest are
