The Lab X Series of phlebotomy chairs for blood drawing is designed to ensure patient comfort during blood drawing. An extra measure of comfort is provided by the thick, padded, contoured seat and arched back of the chair. These are supported by an equally stable and durable steel frame made of powder coated steel. For clinicians, it is easy for them to adjust the height of the arms and for patients, it makes things more comfortable. These bariatric chairs are available in a variety of sizes, including extra tall and extra wide models that can accommodate patients weighing from 400 to 850 lbs.
