Founded in 1988, Wheelchairs of Kansas (WOK) was started by Lee Frickey in Oberlin, Kansas to meet a unique bariatric need in the healthcare industry. Through hard work and dedication, not only to his craft but to patients and caregivers alike, Lee grew the business and formed Sizewise in 1996. Sizewise, working with a network of independent distributors, thrived in this niche market with WOK acting as a manufacturing arm for the company. In 1998 Sunflower Medical was formed to meet the needs of Government and VA patients nation-wide. Over the next 20 years the Sizewise Family of Companies, consisting of Sizewise, Wheelchairs of Kansas, Sunflower Medical, and American National Manufacturing, would grow to be one of the largest durable medical equipment providers in the country.
Sizewise is a privately owned, global medical equipment manufacturer with more than 20 years’ experience engineering innovative products to meet the needs of bariatric, geriatric, pediatric, and standard patient populations. Supplied through more than 65 branches nationwide, Sizewise offers a range of bed frames, support surfaces, and mobility devices that enhance patient healing and caregiver satisfaction. In September 2019 Sizewise announced the re-naming of its manufacturing plants in Hays, Ellis, and Corona under the name Sizewise Manufacturing.
