Solution Summary: Kneeling Mats
Kneeling mats are used to relieve the pressure on the knee joints that result from kneeling on hard surfaces. Kneeling pads are meant to distribute body weight in kneeling over a larger surface area and protect the knee from hard surfaces.
Workers who kneel put 89% of their body weight on a small surface area. Prolonged kneeling can often lead to injury. Kneeling mats protect the knees by distributing the weight over a larger surface area and reduce the force on the knee caps. Kneeling mats come in a variety of materials.

Prolonged kneeling can cause musculoskeletal disorders (MSDs) such as prepatellar bursitis (housemaid’s knee), which is swelling on the front of the kneecap. Kneeling mats help protect the knees during prolonged kneeling by distributing body weight over a larger surface area and reducing the force passed on to the knee cap.
How Risks are Reduced:
Workers, who spend a good deal of time in the kneeling position, put 89% of their body weight on a small surface area. Prolonged kneeling can often lead to injury. The rationale for using kneeling mats is to protect the knee by distributing your weight over a larger surface area and reduce the force passed on to soft tissue.
Independent studies have shown an association between musculoskeletal disorders and awkward postures (e.g. kneeling), and contact stresses (e.g contact pressures are concentrated in a small area). Knee pads are used to protect the knee by distributing your weight over a larger surface area and reducing the force passed on to soft and hard tissue.
There have not been independent published studies measuring the effect of using kneeling mats on reducing knee-related musculoskeletal disorders. Regardless, health and safety experts believe that workers will be more comfortably and less likely to develop musculoskeletal disorders if they use kneeling mats due to reduced exposure to known risk factors.
Effects on Productivity:
Reducing discomfort associated with kneeling on hard surfaces for prolonged periods may increase productivity because workers would presumably be able to work for longer periods without standing up.
