Summary

SIHOO's budget task chair, with a mesh or cushioned seat, flip-up arms and a three-step recline.

Best for

  • Tight budgets; it is one of SIHOO's lowest-priced ergonomic chairs.
  • Small rooms; the armrests flip up so the chair tucks under a desk.
  • Users up to 330 lb, SIHOO's stated maximum load.
  • Choosing a seat; it comes with a mesh or a cushioned seat.

Good to check first

  • The recline has three positions, up to 135°, rather than a free-floating tilt.
  • A footrest version is offered only with the mesh seat.
  • Returns need the chair unused and in its original packaging, so keep the box until you are sure.

The trade-off

A low price and a compact footprint, with simpler arms and recline than SIHOO's higher models.

What SIHOO highlights

  • Sacral support

    The back has a support aimed at the base of the spine. SIHOO says it steadies your posture from the bottom up.

  • Three-position recline

    The back reclines and locks in three positions, up to 135°.

  • Flip-up armrests

    The armrests flip up out of the way. SIHOO says this helps the chair fit smaller work setups.

  • Wide headrest

    A wide 2D headrest sits at the top of the back for leaning back.

As described by SIHOO on its official pages; not a Chairpedia assessment.
