The Midmark Operator Stool is designed to be comfortable and to also help control the musculoskeletal pain issues that dental patients often struggle with. This works with a contoured seat and a raised front to make the weight in the chair move right. It also uses waterfall front edges to keep pressure on your back thighs under control. It uses many seat sizes and heights to enhance the process of using this right. It has waterfall front edges to make the patient more relaxed and uses a forward tilting feature to make it easier for the hip angle to go at an open space over 90 degrees. This keeps disc pressure from being a burden while the lower back curve is appropriately maintained. Also, the backrest can support the lower best and the adjustable armrests can handle the elbows with relatively ease to keep the lower back under control.
