Office supply store Staples is recalling 124,000 office chairs because the legs on the base can break, causing a fall hazard.

The recall involves Staples and Quill Hazen Mesh Task Chairs. The chair has a five-wheel base, black fabric seat cushion and black mesh seat back. They have an SKU number of 1058246 and item number 26680 printed on a white label on the underside of the seat cushion.

The chairs were sold at Staples stores and online at staples.com, staplesadvantage.com and quill.com from October 2014-April 2017 for between $100 and $180.
