The ErgoX is the chair for people who lean back. Most budget ergonomic chairs are built for the upright, typing posture and tolerate the occasional lean. The ErgoX reverses that: its recline goes deep enough to read, take a call, or watch a render finish, and the footrest slides out from under the seat to meet your calves when you get there. Upright, it behaves like a normal mesh task chair with 3D arms and a headrest. Reclined, it becomes something the M57 and the Staples Hyken never pretend to be.
The numbers: the ErgoX listed at $299.99 at the time of writing, and FlexiSpot runs coupons on it often enough that it is worth checking the live price. The listing describes a mesh seat, 3D armrests, tilt and recline, and the footrest; FlexiSpot does not publish a CRI-style spec sheet for chairs, so we judge it by use, not by a claimed weight rating we cannot verify. If you need a chair rated for 350 lb or more, our big and tall chairs guide covers the ones that publish that number.
What it is not: a Steelcase. The recline mechanism is a spring tension knob, not a weight-activated system, and the warranty is measured in years, not a decade. At about $300 it sits squarely in the tier our office chair price index calls the value band, and within that band it is the chair to buy if the footrest matters to you. It is enrolled in Amazon's Creator Connections program, which changes nothing about the verdict.
Our Pick
The best office chair with a built-in footrest we have found under $350. The ErgoX pairs a mesh seat and back with 3D armrests, a lumbar pad that follows you as you move, and a recline deep enough to actually use the footrest. It costs about $110 more than the SIHOO M57, and the footrest and recline are the whole reason to pay it.
Buy it if you sit for eight-plus hours, take calls or read leaning back, and want to put your feet up without a separate ottoman. It also suits people who found the M57 too upright. If you never recline past a few degrees, the footrest is dead weight and the M57 is the better $190.
What we don't like
The footrest is a slide-out pad, not a padded leg rest, so it supports calves rather than cradling them. The mesh seat is firmer than a foam seat and some readers prefer foam for long sits. The headrest adjusts in height and angle but sits a little forward for taller users, and the chair weighs more than the M57, which matters on carpet.
