Product Features:
Most office chairs are either with arms or armless. But there are some days you really need both. Like when you want to rest back while resting each arm, and those times you need to scooch close into your desk and you don’t want those armrests getting in the way. So we created, the ErgoFLIP.
Armrest or Arm-less... You Choose!
Adjustable Armrests flip up and down so you can position to your workstation or your mood. The Ergo Flip also features a full length backrest and headrest. It hugs your spine completely, aligning your back and reduscing compression and pain.
The ErgoFlip Keeps You Cool Under Pressure.
No one likes mesh chairs that leave grill marks on the body. And our breathable ElastoMesh provides optimal airflow to avoid sweating and sticking, while its softness conforms to your body, without feeling "wiry". So of course, we applied this same durable mesh technology across the entire chair.
