“Lumbar” support has been the bane of the ergonomic office chair market for years, with the supposed promise of a pain-free experience for hundreds of dollars. Sihoo sought out a change, and the result is an ergonomic office chair with full-body adaptive support for just under $500.

The Sihoo Doro C300 Pro V2 office chair isn’t like other chairs you might find for your office space. It comes from a company that has 15 years of experience backing it up and has expanded to selling in over 100 countries. With that and the fact that its chairs sit in over 10 million households worldwide, Shioo has learned that static seating is not only uncomfortable, but leaves lasting effects on your body.

The Sihoo Doro C300 Pro V2 is the first full-body adaptive ergonomic chair using a few proprietary designs. Unlike other chairs that offer comfortable support in one position, but lose that structure once you move – as human bodies do – the Sihoo Doro C300 Pro V2 is designed to adapt to your movement. It uses real-time gravity sensing to track body movements. Those movements translate into support that moves as you do.

For instance, sliding into a reclining position would normally create a gap between your back and the chair. With Sihoo’s “DynaCore” system, the headrest, lumbar, SyncroFlex backrest, and 8D bionic armrests all adapt as you move or recline – up to 135 degrees. Even if you adjust it by the slightest amount, the chair dynamically adjusts to ensure it retains support.
