All of our Motorized Blood Donor Chairs use a 24 Volt motor system that can accomodate any electrical connection worldwide to be used in 110V up to 230V systems. All Dacor Blood Donor Chairs are hand constructed, with an all-hardwood frame. Dacor Chairs are rated as fine funiture which are ergonomically designed for comfort using Sinuous spring system, a fabric liner of flexilators, which act as an insulator and stabilizer over the springs and several layers of premium foam for maximum comfort. Our chairs go above and beyond industry standards in the materials and construction we use, in-which most of the competition, only uses 3" foam glued to plywood. All components including the foam, and our top-quality, contract-grade vinyl pass California TB 117 on flammability. A wide selection of vinyl colors are available for your Blood Donor Chair, treated with an antimicrobial/antibacterial protective coating that extends the life of the vinyl and against stains, abrasions, and bacterial growth. An adjustable actuator motor or manual lever provides smooth positioning. Easy adjustable arm pads, for donor and caregiver comfort.
